(the answer is A I just need an explanation to why in order to show my work)
Based on the graphs of the functions f(x) = 2x + 1, and g(x) = 2(x + 3) + 1, a statement which correctly compares the graphs include the following: A. The graph of g is the graph of f translated 3 units left.
What is a translation?In Mathematics, the translation of a geometric figure to the left simply means subtracting a digit from the value on the x-coordinate (x-axis) of the pre-image of a function.
On the other hand, a geometric figure that is translated up simply means adding a digit to the value on the y-coordinate (y-axis) of the pre-image or parent function.
Mathematically, a horizontal translation to the left is modeled by this mathematical expression g(x) = f(x + N) while a vertical translation to the positive y-direction (upward) is modeled by this mathematical expression g(x) = f(x) + N.
Where:
N represents an integer.g(x) and f(x) represent a function.Translating the graph of function f, we have:
g(x) = f(x + N)
g(x) = 2(x + 3) + 1

How do you find the base value?
The base value of a numeral system can be founded by counting the number of unique digits or symbols used in the system.
FIND THE BASE VALUEThe base value of a numeral system can be determined by counting the number of unique digits or symbols used in the system. For example, in the base 10 numeral system, which is commonly used in everyday life, the base value is 10 because it uses the digits 0 through 9. In the base 2 numeral system, which is also known as binary, the base value is 2 because it only uses the digits 0 and 1.
Another way to find the base value is to look at the exponent of the highest power of the base in the numeral system. For example, in the number 42 in base 10, the highest power of 10 is 10¹, which is 10. Therefore, the base value is 10. Similarly, in the number 1010 in binary, the highest power of 2 is 2³, which is 8. Therefore, the base value is 2.
It's important to note that when working with different numeral systems, it is essential to know the base value in order to understand the value of the number being represented.

Step-by-step explanation:
Is X² and 2x like terms?
Answer: No, x^2 and 2x are not like terms. Like terms are terms that have the same variable raised to the same exponent. In this case, x^2 and 2x have the same variable, but they are raised to different exponents, so they are not like terms.
Terms can be added or subtracted together, but terms that are not like terms cannot be combined.
For example:
5x^2 and 2x^2 are like terms, so they can be added together (5x^2 + 2x^2 = 7x^2)
5x and 2x are like terms, so they can be added together (5x + 2x = 7x)
On the other hand:
5x^2 and 2x are not like terms, so they cannot be added together.

Rashon has $780 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
He buys a new bicycle for $481.28.
He buys 3 bicycle reflectors for $10.78 each and a pair of bike gloves for $32.64.
He plans to spend some or all of the money he has left to buy new biking outfits for $44.95 each.
Write and solve an inequality which can be used to determine oo, the number of outfits Rashon can purchase while staying within his budget.
The inequality is x ≤ 5.09, where x is the number of outfits. Rashon can buy at most 5 outfits while staying within his budget.
To determine the number of biking outfits Rashon can buy while staying within his budget, you can set up an inequality using the information provided.
First, calculate the total cost of the reflectors and gloves:
3 reflectors × $10.78 + $32.64 = $38.34 + $32.64 = $71
Then, subtract the cost of the bicycle, reflectors, and gloves from Rashon's budget: $780 - $481.28 - $71 = $227.72
Now, you can use this remaining amount to determine the number of biking outfits Rashon can buy.
Let x be the number of outfits he can buy
You can set up an inequality as follows:
44.95x ≤ $227.72
Dividing both sides by 44.95:
x ≤ 5.09
However, since the number of outfits is an integer, he can only buy 5 outfits at most.

Aaron's car gets an average of 15 miles to the gallon in the city, and he pays an average of $1.09 per gallon of gas. He drives 10.5 miles round-trip 22 days a month for work. Aaron pays $79 per month to park his car in an underground garage. If you include his monthly gasoline cost, what is his average daily cost (22 days per month) of driving his car to work?
The average daily cost of Aaron of driving his car to work is $5.1169.
What is Average Cost?Average cost is calculated by dividing the total cost by the total output quantity.
Miles for a round trip for 1 day = 10.5 miles
Since it is round trip, total miles for 1 day = 10.5 × 2 = 21 miles
Miles for a round trip for 22 days = 21 × 22 = 462 miles
Gallons for 15 miles = 1 gallon
Gallons for 1 mile = 1/15 gallons
Gallons for 462 miles = 30.8 gallons
Cost per gallon = $1.09
Cost for 30.8 gallons = 30.8 × 1.09 = $33.572
Payment for car parking = $79
Total cost per month = $33.572 + $79 = $112.572
Average daily cost = $112.572 / 22 = $5.1169
Hence the average cost per day is $5.1169.

What is the formula of the slope when given two coordinates of two points?
The formula for the slope (also known as the "rise over run" or "gradient") of a line when given the coordinates of two points is:
m = (y2 - y1) / (x2 - x1)
Where (x1, y1) and (x2, y2) are the coordinates of the two points, and m is the slope of the line.
Note that the coordinates must be in a Cartesian coordinate system, and the points must be distinct, otherwise, the denominator (x2 - x1) will be zero and the division by zero is not defined.
For example, if you have two points (2, 4) and (6, 8), you can use the slope formula to find the slope of the line:
m = (8-4) / (6-2) = 4/4 = 1
The slope of the line is 1

Two triangles are congruent if and only if they have the same shape and size.
What is triangle ?
A triangle in which it is having three sides , three angles and the sum of three angles is always 180 degrees.
So, there are several ways to find out if two triangles are congruent, so we will study the triangles above to find the answers:
Case a. (AAS - Angle, Angle, Side)
AAS stands for "angle, angle, side" and means that we have two triangles where we know two angles and the non-included side are equal. So, for the figure above it is true that:
∠B = ∠E
∠A = ∠D
Case b. We don't have any information about this case that allows us to get a conclusion about congruence. Recall that for congruent triangles you need to compare three elements two by two.
Case c. (SSS - Side, Side, Side)
SSS stands for "side, side, side" and means that we have two triangles with all three sides equal. So, for the figure:
Case d. We only have two equal elements, but it is necessary to have three elements for comparing them doing the comparison two by two. There is not enough information for getting a conclusion.

The pair in the solution of the equation -2x + 3y = 6 is (0,2).
Solution of equationThe set of all values that, when substituted for unknowns, make an equation true is known as the solution.
Solution of linear equation in two variablesA specific location on the graph is the solution of a linear equation in two variables, where ax+by = c, meaning that when the x-coordinate is multiplied by a and the y-coordinate is multiplied by b, the sum of these two values equals c. There are essentially an endless number of solutions to a linear equation with two variables.
Now in the question,
To find the pair of solutions of the equation -2x + 3y = 6, we satisfy all the pairs one by one in the given equation
1. Putting the value of (x, y) as (-3,4) in the equation we get-
-2*-3 +3*4 = 6 ⇒ 18 = 6
Therefore LHS ≠ RHS
Hence it is not the solution to the equation.
2. Putting the value of (x, y) as (3,-4) in the equation we get-
-2*3 + 3*-4 = 6 ⇒ -18 = 6
Therefore LHS ≠ RHS
Hence it is not the solution to the equation.
3. Putting the value of (x, y) as (0,2) in the equation we get-
-2*0 + 3*2 = 6 ⇒ 6 = 6
Therefore LHS = RHS
Hence it is the solution to the equation.
4. Putting the value of (x, y) as (3,0) in the equation we get-
-2*3 + 3*0 = 6 ⇒ -6 =6
Therefore LHS ≠ RHS
Hence it is not the solution to the equation.
Thus (0,2) is the solution of the equation.

227 18-inch cubes can fit inside the rectangular prism.
How is this determined?You may calculate how many 18-inch cubes can fit within a rectangular prism by dividing the rectangular prism's overall volume by the volume of a single 18-inch cube.
A rectangular prism's volume can be calculated using the formula length x width x height. In this instance, the dimensions are 312 inches long, 212 inches wide, and 3 inches high. As a result, the rectangular prism has a volume of 1,326,720 cubic inches (312 x 212 x 3).
A single 18-inch cube has a volume of 18 x 18 x 18 = 5832 cubic inches.
We divide the volume of the rectangular prism by the volume of a single 18-inch cube to get the number of 18-inch cubes that can fit inside: 1,326,720 / 5832 = 227.
Therefore, the rectangular prism can accommodate 227 18-inch cubes.

One of the triangles' base length, b, is 3 cm. Thus, the correct answer is A.
Two congruent triangles and a rectangle were formed from the trapezoid. The two triangles are 12 cm in height. The rectangle is 12 cm in height, 14 cm in width and the base side is 20 cm. It's worth noting that a congruent triangle has the same three sides and three angles.
The triangle's base length may be calculated as follows:
Triangle area : 1/2 × base × heightThe sides of the triangle may be calculated using the area of the trapezoid:
Trapezoid area : 1/2 × (a + b)hWhere:
a : the top sideb : base sideh : heightHence:
Trapezoid area : 1/2 × (a + b)hTrapezoid area : 1/2 × (14 + 20)12Trapezoid area : 1/2 × 34 × 12Trapezoid area : 34 × 6Trapezoid area : 204 cm²We know that the height of the triangles is 12 cm and the area of the trapezoid is 204 cm². The area of the rectangle is also given as 14 cm x 12 cm = 168 cm². This information may be used to construct the equation:
204 = 2(1/2bh) + (14 x 12)Solving for b, we get:
204 = 12b + 16812b = 36b = 36/12 b = 3 cmTherefore, the base length of the triangle is 3 cm, and the correct answer is A.

If b = 3 in. And h = 8 in. , what i the area of the triangle?
So, the area of the triangle is 12 square inches.
In a two-dimensional plane, the area of a triangle is the region enclosed by it. A triangle, as we all know, is a closed form with three sides and three vertices. Thus, the area of a triangle is the total space filled by the triangle's three sides. The typical formula for calculating the area of a triangle is half of the product of its base and height.
The area of a triangle can be found using the formula: (1/2) * b * h
Given that b = 3 in. and h = 8 in., the area of the triangle would be:
(1/2) * 3 * 8 = (1/2) * 24 = 12 square inches.

What is meant by equation of line?A line is a straight, thickness-free, one-dimensional object in geometry that extends indefinitely in both directions.
An object that extends without end in both directions is referred to as a line. Arrowheads are typically used to depict it to demonstrate how it never ends. A line segment is an area within a line that has two end points. Half of a line with one end point makes up a ray. Angle is formed by two rays that have the same terminal point.
Let A(0, 3) this point is the y-intercept of the line B(2,6)
The equation of the line into slope intercept form is equal to y = mx + b
where, m is the slope
b is the y-coordinate of the y-intercept = 3
Find the slope of the line m
The formula to calculate the slope between two points is equal to [tex]$m=\frac{y_ 2-y_ 1}{x _2-x _1}$[/tex]
substitute the values
m = (6 - 3)/(2 - 0)
simplifying the equation, we get
m = 3/2
m = 1.5
The equation of the line is y = 1.5x + 3.
