Answer:
A, B, D, F
Step-by-step explanation:
Given
f(x) = (x + 3)(x - 1)(x - 2)(x + 2)
To find the zeros let f(x) = 0, that is
(x + 3)(x - 1)(x - 2)(x + 2) = 0
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3 → B
x - 1 = 0 ⇒ x = 1 → F
x - 2 = 0 ⇒ x = 2 → D
x + 2 = 0 ⇒ x = - 2 → A
To solve this system of equations, start by plugging your equation for x wherever x appears in your second equation, giving you (y-3)+3y=13. Now, combine like terms, (y-3)+3y=13 => 4y-3=13, solve for y by adding 3, 4y-3=12 => 4y=16, divide by 4, 4y=16 => y=4. Now that you have your y value, plug it into the equation for x to get the x value, x=y-3=4-3=1. This makes your solution (1,4), answer choice A
Answer:
12
Step-by-step explanation:
plug in -7 where x is
5 - (-7) = 12
