Replace f(x) with 0 and solve for x. We do this because the x intercepts always occur when y = 0. Keep in mind that y = f(x).
f(x)=x^3-9x^2+20x
0=x^3-9x^2+20x
x^3-9x^2+20x = 0
x(x^2-9x+20) = 0 .... factor out GCF x
x(x-5)(x-4) = 0 ... factor the stuff inside
x = 0 or x-5 = 0 or x-4 = 0 ... zero product property
x = 0 or x = 5 or x = 4

Answer:
q=8
Step-by-step explanation:
To solve for q, we need to get q by itself. To do this, preform the opposite of what is being done to the equation. Also, everything must be done to both sides of the equation.
8q-15=49
Add 15 to both sides, since 15 is being subtracted.
8q-15+15=49+15
8q=64
Divide both sides by 8, since 8 and x are being multiplied.
8q/8=64/8
q=8
Answer:
The correct answer is A 27.46
