The local frozen yogurt shop determines the total cost of a cup of yogurt using the formula y = 2 + 0.75x, where x represents the number of ounces. If you can spend between $2 and $5, what is the DOMAIN of this situation
Answer: 0 ≤ x ≤ 4
Step-by-step explanation:
The cost equation can be written as:
y = $2 + $0.75*x
Where x is the number of ounces that you buy.
If you can spend between $2 and $5, then we have the inequality:
$2 ≤ y ≤ $5
replacing y by the above equation:
$2 ≤ $2 + $0.75*x ≤ $5
Now let's solve this for x.
$2 - $2 ≤ ($2 + $0.75*x) - $2 ≤ $5 - $2
$0 ≤ $0.75*x ≤ $3
now we can divide bt $0.75 in the 3 sides:
$0/$0.75 ≤ ($0.75*x)/$0.75 ≤ $3/$0.75
0 ≤ x ≤ 4
Then the domain is:
D: 0 ≤ x ≤ 4
or we can also write this as:
D = x ∈ [0, 4]

Answer:
[tex]m=0[/tex]
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Step-by-step explanation:
Step 1: Define
Point (-12, 1)
Point (4, 1)
Step 2: Find slope m
Substitute [Slope Formula]: [tex]m=\frac{1-1}{4+12}[/tex]Subtract/Add: [tex]m=\frac{0}{16}[/tex]Divide: [tex]m=0[/tex]Answer:
zero; it is a horizontal line
Step-by-step explanation:
equation of slope: [tex]\frac{y1-y2}{x1-x2}[/tex] (-12, 1) (4, 1)
[tex]\frac{1-1}{-12-4}[/tex] = [tex]\frac{0}{-16}[/tex]
Because the numerator is zero, the slope of the line is zero. It is a horizontal line.
Mrs. Nally's swimming pool is 10 feet by 6 feet. She paves the area around it with a sidewalk x feet wide, using 80 square feet of a new type of non-slip concrete. How wide is the sidewalk? A. The sidewalk is 20 feet wide. B. The sidewalk is 4 feet wide. C. The sidewalk is 10 feet wide. D. The sidewalk is 2 feet wide.
Answer:
The sidewalk is 2 feet wide
Step-by-step explanation:
The area of the sidewalk is given as 80 square feet
The length and width of pool
including side walks will be;
10 + 2x and 6 + 2x
To get the area of the side walk
That will be area of total minus area of the pool
That will be ;
(10 + 2x)(6 + 2x) - 10(6) = 80
60 + 12x + 20x + 4x^2 - 60 = 80
4x^2 + 32x -80 = 0
x^2 + 8x -20
x^2 + 10x - 2x - 20 = 0
x(x + 10) -2(x + 10) = 0
(x-2)(x + 10) = 0
x = 2 or -10
since width cannot be negative;
The sidewalk is 2 feet wide

Answer:
(4, -2)
Step-by-step explanation:
if you do process of elimination you find that 'a' doesn't work out but 'b' will . . . substitute -2 for 'y' and 4 for 'x' and see if the equation is true
-2 = -3/4(4) + 1
-2 = -3 + 1
-2 = -2

What is the slope of the line passing through the point 2 comma negative 1 and the origin?
Answer:
- 1/2 or - 1.5
Step-by-step explanation:
I would suggest using a table
x y
2 -1
0 0
from -1 to 0, you add 1
from 2 to 0, u subtract 2
so y/x
1/-2
Your slope will be -1/2 or -1.5

The lines in the graph of part A don't intersect at two whole numbers on the coordinate grid. Estimate the values of the solution to the nearest one-fourth of a unit. Then substitute the x- and y-values of the approximate solution into the two equations. How close do you get to the constant numbers in each equation?
Answer:
The solution lies at approximately (4.25,6.5).
Step-by-step explanation:
The estimate is pretty close for both equations. For the first equation, the estimate results in a value that is only 0.2125 units away from the constant. For the second equation, the estimate results in a value that is only 0.25 units away from the constant.

Step-by-step explanation:
A store is having a summer sale where all prices are 25−30% off. If you want to buy a pair of shoes that costs $50.00, what could be the sale price for this pair of shoes? An 8% sales tax must be applied to the sale price. What would be the final cost of the pair of shoes, including the sales tax?
Answer:
Before Tax: $37.50 and $32.50
After-Tax: $40.50 and $35.10
Step-by-step explanation:
In order to calculate the sales price we need to turn these percentages into the proper decimals, since they are discounts we would do this by dividing each percentage by 100 and then subtracting them from 1. Then we use those decimals and multiply them by the original cost of the shoes.
25% / 100 = 0.25
1 - 0.25 = 0.75
50.00 * 0.75 = $37.50
30% / 100 = 0.35
1 - 0.35 = 0.65
50.00 * 0.65 = $32.50
Now we see that the sales price for these shoes would range between $37.50 and $32.50. Now we need to add an 8% sales tax, we do this by dividing this percentage by 100 and adding 1 to it. Then we multiply this new value by the new sales prices.
8% / 100 = 0.08
0.08 + 1 = 1.08
$37.50 * 1.08 = $40.50
$32.50 * 1.08 = $35.10

which system of inequalities is shown in the graph
Answer:
The system of inequalities shown in the graph is x ≤ 4 and y > 1 ⇒ C
Step-by-step explanation:
The equation of a vertical line is x = a, where a is the x-coordinate of any point on the lineThe equation of a horizontal line is y = b, where b is the y-coordinate of any point on the lineIn the given figure, there are 2 lines, let us find the equations of them, then write the inequalities which represent the shaded areas
∵ The purple line is a vertical line
∵ It is cross the x-axis at the point (4, 0)
→ By using the first rule above
∴ The equation of the purple line is x = 4
∵ The purple line is solid and the shaded area left the line
∴ The sign inequality is ≤
∴ The inequality of the purple area is x ≤ 4
∵ The blue line is a horizontal line
∵ It is cross the y-axis at the point (0, 1)
→ By using the second rule above
∴ The equation of the blue line is y = 1
∵ The blue line is dashed and the shaded area above the line
∴ The sign inequality is >
∴ The inequality of the blue area is y > 1
∴ The system of inequalities shown in the graph is x ≤ 4 and y > 1

Mr. Vaughn set aside $200 of his income each month for years toward home repairs. He spent 30% of the money he set aside to replace a broken water heater. How much of the money he set aside did Mr. Vaughn have left after paying for the water heater?
Answer:
The answer is that Mr. Vaughn have $140 left from the money he set aside after paying for the water heater.
Step-by-step explanation:
In order to find the answer, first you have to calculate 30% of the amount Mr. Vaughn set aside of his income each month to determine the money he spent to replace the broken water heater:
$200*30%=$60
Now, you have to subtract the amount that represents the 30% from the amount he set aside:
$200-$60=$140
According to this, the answer is that Mr. Vaughn have $140 left from the money he set aside after paying for the water heater.

Jacob combined watermelon, mangos, and blueberries to make a fruit salad. The expression 16p + 24c + 32w represents the total number of fruit in the mix. Jacob wants to divide the fruit salad into equal servings, but he does not know how many. Use factoring to write expressions that will help Jacob divide the fruit salad into 4 servings or 8 servings. So, you need TWO expressions: one expression for 4 servings and one expression for 8 servings.

Step-by-step explanation:
845/1160 = 0.728
116.5/174 = 0.669
42.25/58 = 0.728
23.4/29 = 0.806
16.9/23.2 = 0.728
25.35/34.8 = 0.728
Hence the 2nd, 4th and 5th options are correct.
