Plug in - 5 where X is.
f(- 5) = (- 5)^2 - ( - 5).
(- 5)( - 5) = 25 so now we have 25 - (- 5). Because there are two negatives back to back, the number becomes a positive so the equation becomes 25 + 5 = 30.
f(- 5) = 30.
Answer:
x = 
Step-by-step explanation:
Given
=
( cross- multiply )
25 × 2x = 5 × 4
50x = 20 ( divide both sides by 50 )
x =
= 
64 divided by 8 = 8
So you're answer would be 8

Answer:
x=133
Step-by-step explanation:
Given: m║n
This means that 147 and x+14 are <em>alternate exterior angles</em>. This also means that they are equivalent. We can use this information to set up an equation:
x+14=147
Subtract 14 from both sides to isolate x
x=133
