Function would be f(x) = 5x+85
here, x= 15
5(15)+85 = 75+85 = $160
Answer:
x = 9
Step-by-step explanation:
Perimeter = 2 * width + 2 * length
= 2*11 + 2(x + 5) = 50
2x + 10 + 22 = 50
2x = 50 - 10 - 22
2x = 18
x = 9
Answer:
The correct answer is A, Point P
Step-by-step explanation:
since the additive inverse of 2 is -2 because -2 + 2 = 0 the correct choice must be choice A, Point P.
So the first one, 1.2 >11/5. and the second one 1/3> 1/2
Answer:
f(x) = x³ - 5x² - 9x + 45
Step-by-step explanation:
Given x = a, x = b are the zeros of a polynomial, then
(x - a), (x - b) are the factors and f(x) is the product of the factors.
Here the zeros are x = - 3, x = 3 and x = 5, thus
(x + 3), (x - 3) and (x - 5) are the factors and
f(x) = (x + 3)(x - 3)(x - 5) ← expand the first pair of factors using FOIL
= (x² - 9)(x - 5) ← distribute
= x³ - 5x² - 9x + 45
