Let's say the function for the discount is f and the function for the coupon is g
f(x)= 0.1x
g(x)= x-150
If you want to the the discount then the coupon, your composition function would look like this:
f(g(x))=0.1(x-150)

4 |x = 5| = 20
First, divide both sides by 4. / Your problem should look like:
Second, simplify

to 5. / Your problem should look like:
Third, break the problem into 2 equations. / x + 5 = 5 and -(x + 5) = 5
Fourth, solve x + 5 = 5. /
Cancel 5 on both sides. /
Fifth, solve -(x + 5) = 5 /
Simplify brackets /

Add 5 to both sides /

Add 5 + 5 /

Multiply both sides by -1 /

x = -10
Sixth, collect the solutions to the problems. / Your problem should look like:

Answer:
x = -10, 0
Answer:
Insert equation into desmos (free online graphing calculator)
the two x intercepts are -0.33333 and 1.5
1.83333 is the answer

Answer:
Step-by-step explanation:
a) (2,350),(5,530)
b) (530-350)/(5-2)=60
c) y=60x+b, using point (2,350)
350=60(2)+b
b=230
w=60t+230
c) w(7)=60(7)+230
w(7)=$650
