In the mail, you receive a coupon for $5 off for a pair of jeans, which is represented by the function j(x)=x−5. When you arrive at the store, you find that all jeans are 25% off, which is represented by the function s(x)=0.75x. Which of the functions below represents how much you would pay for a pair of jeans, C(x)=s(j(x)) , if you use the coupon first followed by applying the discount from the store? (Do not consider tax.) A .C(x)=0.75x−5
B .C(x)=0.75(x−5)
C .C(x)=0.75x−x−5
D .C(x)=x−5−0.75

B

Step-by-step explanation: The function C(x) = s(j(x)) shows you how to solve it.

First in the parenthesis j(x) so you have to substitute since they told you

j(x) = x-5

Next s(x-5) and s(x-5) = 0.75(x-5) through substitution  

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
