This question is incomplete
Complete Question
Leah would like to earn at least $120 per month. She babysits for $5 per hour and works at an ice cream shop for $10 per hour. Leah cannot work more than a total of 20 hours per month. Let x represent the number of hours Leah babysits and let y
represent the number of hours Leah works at the ice cream shop.
Answer:
The inequalities to solve this question is given as:
x + y ≤ 20
5x + 10y ≥ 120
Leah must spend: 16 hours babysitting and 4 hours working at the ice cream shop to earn at least $120
Step-by-step explanation:
Let x represent the hours she number of hours she babysits and y represent the hours she works at the ice cream shop. Leah cannot work more than a total of 20 hours per month.
Hence:
x + y ≤ 20 ...... Equation 1
Leah would like to earn at least $120 per month.
She babysits for $5 an hour and works at an ice cream shop for $10 per hour.
Hence, out Equation is given as:
x × $5 + y × $10 = $120
5x + 10y ≥ 120..... Equation 2
The inequalities to solve this question is given as:
x + y ≤ 20
5x + 10y ≥ 120
To find x and y:
x + y = 20
x = 20 - y
5x + 10y = 120
Substitute: 20 - y for x
5(20 - y) + 10y = 120
100 - 5y + 10y = 120
Collect like terms
- 5y + 10y = 120 - 100
5y = 20
y = 20/5
y = 4 hours
Note:
x = 20 - y
x = 20 - 4
x = 16 hours
Hence:
Leah must spend: 16 hours babysitting and 4 hours working at the ice cream shop to earn at least $120

L.B. Johnson Middle School held a track and field event during the school year. The chess club sold various drink and snack items for the participants and the audience. Altogether, they sold 486 items that totaled $2673. If the chess club sold each item at the same price, calculate the price of each item. Do not include units ($) in your answer.
Answer:
Price of each item = 5.50
Step-by-step explanation:
Total items sold = 486
Total price of items sold = $2,673
If the chess club sold each item at the same price,
Price of each item = Total price of items sold / Total items sold
= $2,673 / 486
= $5.50
Price of each item = $5.50
Excluding the units ($) in the answer
Price of each item = 5.50

Plzzzzz helpppppp which equation represents a line which is parallel to the y- axis A. y=x B.y=7 C.x=-8 D.x=1/2y
Answer:
C.) x=-8
Step-by-step explanation:
The y-axis is a line going up and down. You can think of it as x=0. Parallel means the two line never intersects so x=-8 is the answers because it will never intersects with x=0.
HELP I need to fine the slope-intercept form. Please it’s a timed assignment I only have two try’s and I already used one
Answer:
5. y = -1/2x + 6
6. y = 1/2x + 150
7. y = 10x + 20
8. y = 25x
Step-by-step explanation:
Look at the y-intercept and eliminate the answers you dont need.
Then find the slope of each.
please solve this equation and show work 4y−70=12y+2
Answer:
Step-by-step explanation:
Simplifying 4y + -70 = 12y + 2
Add -12y to each side of the equation. -70 + 4y + -12y = 2 + 12y + -12y
Add 70 to each side of the equation. -70 + 70 + -8y = 2 + 70
Divide each side by -8.
So y = -9 is your answer.

If F(x) = 9x, which of the following is the inverse of F(x)?
O A. F'(x) = x-9
OB. F'(x) =
C. F'(x) = x + 9
D. F1(x) = 9
Answer:
Should be x/9
Step-by-step explanation:
The inverse of the function is F' ( x ) = x/9
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as F ( x )
Now , the value of F ( x ) is
F ( x ) = 9x be equation (1)
Now , let the inverse of the function be represented as F' ( x )
where , the values of y are interchanged with x
So , the equation is
y = 9x
when x in interchanged ,
x = 9y
On solving for y , we get
Divide by 9 on both sides , we get
y = x / 9
So , the inverse of the function is F' ( x ) = x/9
Hence , the inverse of the function is F' ( x ) = x/9

Hailey's hair grows at a rate of 1/2 inch per month. How many months will it take her hair to grow a total of 8 inches?
Answer:
16 months for it to grow 8 inches
Answer:
16
Step-by-step explanation:
growth in 1 month = 1/2 inches
growth in x months = x*1/2 inches
total growth = 8 inches
thus,
8 = x*1/2
x = 8 / (1/2)
= 16

Tanya is printing a report. There are 92 sheets of paper in the printer, and the number of sheets of paper p left after t minutes of printing is given by the function p(t) = −8t + 92.
Here is the complete question I was able to find:
Tanya is printing a report. There are 92 sheets of paper in the printer, and the number of sheets of paper p left after t minutes of printing is given by the function p(t) = -8t + 92.
How many minutes would it take the printer to use all 92 sheets of paper?
Answer:
The printer needs 11.5 minutes to use all 92 sheets of paper.
Step-by-step explanation:
Given the function
p(t) = −8t + 92
We need to determine how many minutes would it take the printer to use all 92 sheets of paper?We know that putting p(t) = 0 means we will be able to determine the time when all the 92 sheets of paper will have been printed.
Because, putting p(t)=0 means there won't be any sheet left.Thus, plug in p(t) = 0 in the function and calculate the time 't'
p(t) = −8t + 92
0 = −8t + 92
adding 8t to both sides
8t = −8t + 92 + 8t
8t = 92
dividing both sides by 8
8t/8 = 92/8
t = 11.5 minutes.
Thus, the printer needs 11.5 minutes to use all 92 sheets of paper.

What is the measure of the indicated angle ?
Answer:
The measure of the indicated angle is 72°
Step-by-step explanation:
If two parallel lines intersected by a transversal, then
There are pairs of corresponding angles equal in measuresThere are pairs of alternate interior angles equal in measuresThere are pairs of alternate exterior angles equal in measuresThere are pairs of adjacent interior angles that are supplementaryIn the given figure
∵ There are two parallel lines intersected by a transversal
∵ The angle of measure 108° and the indicated angle are adjacent
interior angles
∴ They are supplementary
∵ The sum of the measures of supplementary angles is 180°
∴ 108 + indicated angle = 180
→ Subtract 108 from both sides
∴ The measure of the indicated angle = 72°
Select all that apply.
