Y = total amount
x = number of months
Equation : y = 20 + 10x
-------------------------------------
Ans: y = 20 + 10x
-------------------------------------
Answer:
y=5x-7
-3x-2y=-12
Step-by-step explanation:
-3x-2(5x-7)=-12
-3x-10x+14=-12
-13x+14=-12
-13x=-26
y=5x-7+5x2-7=10-7=3
Answer:
87.92
Step-by-step explanation:

c= Circumference
d= Diameter

Answer: f(x) and g(x) are inverses of each other
<u>Step-by-step explanation:</u>
To find the inverse of a function, swap the x's and y's and then solve for "y"
f(x) = 5x + 2
y = 5x + 2
Swap:
x = 5y + 2
<u> -2 </u> <u> - 2 </u>
x - 2 = 5y
<u>÷5 </u> <u>÷5 </u>
