How can you tell how many solutions a linear equation will have by looking at the equation?

The car can go 44.25 miles on one gallon of gas

Xavier's car used 1 1/3 gallons to travel for 59 miles

The number of miles travelled on one gallon of gas can be calculated as follows

1 1/3 gallons= 59 miles

1 gallon= x

Cross multiply both sides

4/3x= 59

4x= 177

x= 177/4

x= 44.25

Hence Xavier's car can travel 44.25 miles on one gallon of gas

Lets set the cost of the cost as the y-axis and the amount of fish as the x-axis. 12.50, a constant and the y-intercept, is the price when you don't have any fish.

0.2 is the slope and in this case, the amount of 1 fish.

0.2x + 12.5 is the total amount as every fish added adds 20 cents. 12.5 is the fishtank which you need to get before getting any fish.

Find the whole amount of what you're looking for to get a percentage of.

To calculate the percentage, divide the number.

Add 100 to the value.

A % is a quantity or ratio that, in mathematics, represents a portion of one hundred. It's frequently represented by the sign "%" or just "percent" or "pct." For instance, 35% is equal to the fraction 0.35 or the decimal 0.35.

The value of the number out of 100 is the proportion of the number. For instance, there are 26 females and 24 boys in a class. As a result, 52 out of 100 students in the class are females, or 52% of the class.

The Latin word "per centum," which meaning "by the hundred," was the source of the English word "percentage." Percentages.

Identify the asset's cost. Get the asset's total depreciable value by deducting the projected salvage value from the asset's purchase price. Determine the asset's useful life. The annual depreciation amount is obtained by dividing the sum of steps (2) and (3) by the figure determined in steps (3).

Depreciation is the practice of deducting the cost of a company asset over a number of years as opposed to just one. There are four primary ways to depreciate assets: linear, twofold declining, sum of the years' digits, and manufacturing units.

As it is given, 1% of left tree is decaying every year.

Number of tree left after 8 years.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

You mix 1/2 quart of blue paint for every 1/3 quart of red paint to make 5 quarts of purple paint.

Let 'x' be the amount of blue paint and 'y' be the amount of red paint. Then the equations are given as,

x / y = (1/2) / (1/3)

x / y = 3/2                        ...1

x + y = 5                          ...2

From equations 1 and 2, then we have

(3/2) y + y = 5

(5/2) y = 5

y = 2 quart

Then the value of 'x' is given as

x + 2 = 5

x = 3 quart

The expression 3(x-2) is equivalent to 3x - 6.

When you distribute the 3 to the term inside the parentheses, you multiply 3 by x and by -2, resulting in 3x - 6.

This is because the distributive property states that for any real numbers a, b, and c, the expression a(b+c) is equivalent to ab + ac. In this case, we have a = 3, b = x, and c = -2, so we can apply the distributive property and get 3x - 6.

You can also think of it as 3 multiplied by (x-2)

3x - 32 = 3x - 6

The one-sided limit that does not exist is given as follows:

lim x -> -6^- f(x).

A one sided limit will not exist when it is outside the domain of the function.

The domain of a function is composed by the set of all the input values of the function, hence on the graph it is given by the values of x.

For this problem, the domain is then given as follows:

-6 ≤ x ≤ 8.

To the left of -6, the function is not defined, hence the one-sided limit that does not exist is given as follows:

The volume of the solid is 4π([tex]\frac{19}{6}[/tex]) and the integral of the f(x) , the line 2y=x, and x=2 is 3([tex]e^{4}[/tex] -1).

What is integral ?

An integral is a mathematical concept that is used to calculate the area under a curve or the total amount of change in a variable over a certain interval.

1)The first step is to find the intersection of the lines 2y=x and x=2. They will intersect at (2,1).

The second step is to find the intersection of the lines 2y=x and x=0. They will intersect at (0,0).

The third step is to find the integral over the region.

∫∫ (6e^(x^2))dxdy = ∫[0,2] (6e^(x^2))dx ∫[0,x/2] dy = ∫[0,2] (6e^(x^2))dx (x/2) = [3e^(x^2)] at [0,2] = 3e^(4) - 3e^(0) = 3(e^4 -1).

2)To find the volume of this solid, we can use the method of cylindrical shells.

we can find the function of the surface (1/3)x+(1/2)y+(1/4)z=1

by using cylindrical coordinates:

x = rcosθ , y = rsinθ , z = z

and substitute them in the equation (1/3)x+(1/2)y+(1/4)z=1

(1/3)rcosθ+(1/2)rsinθ+(1/4)z=1

(1/3)r(cosθ+2sinθ)+(1/4)z=1

z = 4(1-(1/3)r(cosθ+2sinθ))

V = ∫∫∫ 4(1-(1/3)r(cosθ+2sinθ)) rdrdθdz = 4π ∫[0,3] (1-(1/3)r(cosθ+2sinθ)) r^2 dr = 4π ∫[0,3] (1-r+(2/3)r^2) dr = 4π(3 - (3/2) + (2/3)) = 4π(19/6).

Hence , The volume of the solid is 4π([tex]\frac{19}{6}[/tex]) and the integral of the f(x) , the line 2y=x, and x=2 is 3([tex]e^{4}[/tex] -1).

All the points (and only those points) which lie on the graph of the function satisfy its equation.

Thus, if a point lies on the graph of a function, then it must also satisfy the function.

The value of a and b for the given quadrilateral to be a parallelogram is a = 16 and b = 4.

A quadrilateral having two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side. 360 degrees is the sum of all interior angles.

A parallelepiped is a three-dimensional shape with parallelogram-shaped faces.

We know that the opposite sides of a parallelogram are equal in length so we can equate the two sides as follows:

For a:

2a + 6 = 3a -10

Isolate the value of a by moving all the values having a to one side:

2a + 6 = 3a -10

3a - 2a = 6 + 10

a = 16

For b:

6b - 3 = 5b + 1

Isolate the value of b by moving all the values having b to one side:

6b - 3 = 5b + 1

6b - 5b = 1 + 3

b = 4

Hence, the value of a and b for the given quadrilateral to be a parallelogram is a = 16 and b = 4.
