Step-by-step explanation:
Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
1. Change the equation to slope intercept form. Identify the slope and y- intercept of the equation. Be sure to show all your work.
2x + 3y= 1470
2x + 3y -2 = 1470 subtract 2x from both sides
3y= 1470 -2x simplify
3y/3= 1470/3 -2x/3 divide both sides by 3
y= -2/3x +490 simplify
-⅔ is the slope and 490 is the y- intercept
2. Describe how you would graph this line using the slope- intercept method. Be sure to write in full sentences.
Start at 490 on the y axis. After that you would use rise over run, down 2 units and right three. Do this until you reach the end of the graph, then go oppisite; up 2 left 3
3. Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.
I CANNOT figure out how to make the equation into notation form. Can someone please help?

Step-by-step explanation:
Kendra sold 50 boxes of cookies in 20 days. Her older sister, Alecia, sold twice as many boxes in half as many days. If the two girls continued at the same sales rates, how many total boxes would both girls have sold if they had both sold cookies for 40 days?
Answer:
Alecia would have sold 400 boxes.
Kendra would have sold 100 boxes.
Step-by-step explanation:
First we have to find the unit rate of each girl's cookie sale.
Kendra: 50 ÷ 20 = 2.5
This mean Kendra sold 2.5 cookies each day.
If Alecia sold twice as many boxes, that would be 100 boxes. And if it was in half amount of days, that would be 10 days.
Alecia sold 100 boxes in 10 days.
100 ÷ 10 = 10
She sold 10 boxes each day.
Alecia: 10 × 40 = 400
Kendra: 2.5 × 40 = 100
Answer:
in 40 days Kendra will have sold 100 boxes and her sister sold 160
Step-by-step explanation:
set up proportions for each sister
Kendra: 50/20 = b/40 cross-multiply to get 20b = 200
Alecia: 40/10 = b/40 cross-multiply to get 10b = 1600

What are the coordinates of R' after a dilation by a scale factor of 3, centered at the origin, followed by the translation (x, y) - (x, y + 3)?
A. (9, 8)
B. (12, 18)
C. (9, 18)
D. (9, 24)
9514 1404 393
Answer:
C. (9, 18)
Step-by-step explanation:
Given R(3, 5), a dilation by a factor of 3 will multiply each coordinate to give ...
(9, 15)
Then the translation up by 3 will give you the image coordinates ...
(x, y) ⇒ (x, y+3)
(9, 15) ⇒ (9, 15 +3) = (9, 18)
The coordinates of R' are (9, 18), matching choice C.
_____
Comment on multiple choice answers
As it often does, here it works to "guess" the answer that has the coordinates that are most-repeated. An x-coordinate of 9 is part of 3 answer choices; a y-coordinate of 18 is the only repeated value in the answer choices. If you were to guess, an appropriate guess would be (9, 18). That happens to be correct in this case.
Answer: C. (9,18)

The ticket sales for a concert started at 4:00 P.M. The table shows the linear relationship between the number of tickets remaining and the number of hours since 4:00 P.M.
Which function can be used to find y, the number of tickets remaining x hours since 4:00 P.M.?
a
y = 3,000x + 12,000
b
y = -3,000x + 12,000
c
y = -3,000x + 15,000
d
y = 3,000x + 15,000
Answer:d
Step-by-step explanation:
The function which represents the number of tickets remaining after x hours is b. y = -3,000x + 12,000.
What is a function?A function can be defined as the values of the inputs for which the output is defined. The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
From the given graph we can observe that every hour 3000 tickets were sold.
Assuming hours to be x and tickets remaining at any time is represented
by y and as the tickets were sold we can denote it with a negative sign.
∴ The function which represents the number of tickets remaining after x hours is,
y = -3000x + 12000.
To check whether our function is correct or not we can put any value of x from 1 to 4 in our function.

4. The length of a rectangle is eight more than
twice its width. The perimeter is 96 feet. Find
the dimensions of the rectangle.
Answer:
length = 104/3 ft
width = 40/3 ft
Step-by-step explanation:
Variables:
L = length
w = width
Set up equations:
L = 8 + 2w2L + 2w = 96Substitute L with the first bullet point equation:
2L + 2w = 96
2(8 + 2w) + 2w = 96
16 + 4w + 2w = 96
16 + 6w = 96
6w = 80
w = 40/3 ft
Find L now that you have the value of the width:
L = 8 + 2w
L = 8 + 2(40/3)
L = 8 + 80/3
L = 104/3 ft
Final Values:
length = 104/3 ft
width = 40/3 ft
