Looks to Be answer A have a great day!
Differentiate both sides wrt 
:
By the chain rule, we get
Solve for 
:
That answer is x≤−8
Inequality:
8x−8≤−72
Step number 1: You have to Add 8 to both sides.
8x−8+8≤−72+8
8x≤−64
Step number 2: You have to Divide both sides by 8.
8x
/8 ≤ −64
/ 8
Ur Answer:
x≤−8
Hope this helps :)
Answer:
80x
Step-by-step explanation:
If you pay 80 a month then to find the total you have paid after any number of months you would multiply amount times time which in this case is 80
a constant is the a number on its own so in this case there would be none
a coefficient is the number in front of a variable. Since the equation is 80x the coefficient is 80
