The diagram shows that
AB = 5
AC = AB+BC = 5+2 = 7
DE = 7
DF = DE+EF = 7+x
So,
AB/AC = DE/DF
5/7 = 7/(7+x)
5(7+x) = 7*7
5(7+x) = 49
35+5x = 49
5x = 49-35
5x = 14
x = 14/5
So EF = 14/5 in fraction form
In decimal form, EF = 2.8 (since 14/5 = 2.8)
No.f(-2) = -114, not zero.
(x-4) is the only rational factor of f(x).
Hello there! :)
Answer:
<em><u>*THE ANSWER MUST HAVE A POSITIVE SIGN!*</u></em>
Step-by-step explanation:
First, you subtract by 8 from both sides of an equation.
Then, you subtract by the numbers from left/right.

So just switch x and y to get:
and solve for x.
so f(-1) = x = 2y -10
