Answer:
(7, 0) and (-5, 0)
Step-by-step explanation:
<u>Vertex form</u>
(where (h, k) is the vertex)
Given:

Given:



Therefore:

The x-intercepts are when y = 0






Therefore, the x-intercepts are (7, 0) and (-5, 0)
Answer:
0.53
Step-by-step explanation:
What does x equal? In order to find the relationship between x and y we need to know both values at a given instance. For example, if x = 10 while y = 20/3, then we know that you = 20x/30 or 2x/3.
All but c are correct so the answer is a b and d
Answer:
-2
Step-by-step explanation:
Put the given value in the equation and solve for x.
f(x) = 12
f(x) = 2(x +8)
12 = 2(x +8) . . . . . use 12 for f(x)
6 = x +8 . . . . . . . . divide by 2
-2 = x . . . . . . . . . . subtract 8
