Answer:
a). -6x³ - 12x² b). -12 c). 12
Step-by-step explanation:
a). (g x f)(x) can also equal f(g(x))
= f (2x +4)
= -3x² (2x+4)
= -6x³ - 12x²
b). f(g(-1))
g(-1) = 2(-1) + 4
= -2 + 4
= 2
f(2) = -3x²
= -3(2)²
= -12
c). g(h(3))
h(3) = 3x-1/2
= 3(3) - 1 / 2
= 4
g(4) = 2x + 4
= 2(4) + 4
= 12
Answer:
x = - 2, x = 10
Step-by-step explanation:
Given
x² - 8x - 20 = 0
Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (- 8)
The factors are - 10 and + 2 , since
- 10 × 2 = - 20 and - 10 + 2 = - 8 , then
(x - 10)(x + 2) = 0
Equate each factor to zero and soilve for x
x + 2 = 0 ⇒ x = - 2
x - 10 = 0 ⇒ x = 10
26 paychecks. Because 12 divided by 6 is 2 so you would divide 52 by 2 and get 26.
