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.
2. Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences.
3. Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.
4. Graph the function. On the graph, make sure to label the intercepts. You may graph your equation by hand on a piece of paper and scan your work or you may use graphing technology.
5. Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.
6. Below is a graph that represents the total profits for a third month. Write the equation of the line that represents this graph. Show your work or explain how you determined the equations.

B. 18
C. 36
D. 72
Answer:
The answer is 6 (A)
Step-by-step explanation:
The exact answer is 5.73, but I think in the question they are rounding to the nearest whole number, so the rounded answer is 6.
My work:
C = 2πr
r = C
2π = 36
2·π = 5.72958

Write the equation of a line that is perpendicular to y=-x-6 and that passes through the point (-9,-4).
Answer:
y = x + 5
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes, so the line will have a slope of 1.
Then, plug in the slope and given point into y = mx + b to solve for b:
y = mx + b
-4 = 1(-9) + b
-4 = -9 + b
5 = b
Plug in the slope and b into y = mx + b:
y = 1x + 5
y = x + 5
So, the equation of the line is y = x + 5
Solve these equations as a ordered pair
Y= 2x-3
Y= -x

Find the unknown side of the triangle below (round to the nearest tenth).
A.) 210.5 cm
B.) 5.4 cm
C.) 16 cm
D.) 20.5 cm
Answer:
the answer is D, 20.5cm
Step-by-step explanation:
x is hypotenuse
hypotenuse formula:
[tex]hypotenuse = \sqrt{ {a}^{2} + {b}^{2} } [/tex]
let 15cm = a
let 14cm = b
[tex]x = \sqrt{15 {}^{2} + {14}^{2} } [/tex]
[tex]x = \sqrt{225 + 196} [/tex]
[tex]x = \sqrt{421} [/tex]
[tex]x = 20.5cm[/tex]

f(x) = x + 2
g(x) = 3x^2 - 5
Find (f•g)(x).
Step-by-step explanation:
(f o g)(x)
= f(3x² - 5)
= (3x² - 5) + 2
= 3x² - 3.
(f.g)(x) = 3x^2 - 3
f(x) = x + 2
g(x) = 3x^2 - 5
equation is the relationship between variable and represented as is example of polynomial equation.
f(x) = x + 2
g(x) = 3x^2 - 5
now putting the x = g(x)
in f(x) = x + 2
Thus,
f(g(x)) = 3x^2 - 5 + 2
f(g(x)) = 3x^2 - 3
Thus, (f.g)(x) = 3x^2 - 3
