Answer:
x^2 -10x+25
Step-by-step explanation:
(x − 5)^2
(x-5)(x-5)
FOIL
first x*x = x^2
Outer -5 *x = -5x
inner -5*x = -5x
last -5*-5 =25
Add them together x^2 -5x-5x+25
Combine like terms x^2 -10x+25
13
Step-by-step explanation:
5000(1+.07)^2
5000(1.07)^2
5000(1.14)
5,700
Your final answer should be 5,700$. If you wanna double check you would use the equation fv=bv(1+r/m)^mt
Hello from MrBillDoesMath!
Answer:
(x-8)^(1/3) +2
Discussion:
To find the inverse of a function swap the values of x and y in the original equation y = (x-2)^3 +8 and solve for y.
y = (x-2)^3 +8 => original function. swap x and y values
x = (y-2)^3 + 8 => subtract 8 from both sides
x - 8 = (y -2)^3 => take cube root of both sides
(x-8)^(1/3) = y - 2 => add 2 to both sides
(x-8)^(1/3) +2 = y => y is the inverse
Thank you,
