Answer:
Step-by-step explanation:
f(x) = -5x + 5
g(x) = 8 + 2x
a) (f + g)(x) = f(x) + g(x)
= (- 5x + 5) + ( 8 + 2x )
= - 5x + 2x + 5 + 8
= - 3x + 13
b) (f - g)(x) = f(x) - g(x)
= ( -5x + 5 ) - ( 8 + 2x)
= - 5x + 5 - 8 - 2x
= - 7x - 3
c) (f + g)( 4 )
(f + g)( x ) = - 3x + 13
(f + g) ( 4 ) = - 3 ( 4 ) + 13
= - 12 + 13
= 1
d)(f - g)(- 3)
(f - g) ( x ) = - 7x - 3
(f - g) ( - 3 ) = - 7 ( - 3 ) - 3
= 21 - 3
= 18

Hi there!
Angles that are complementary add up to 90. We know that in order to find the value of x, we'll need to create an equation. This equation would be (x + 15) + 48 = 90. This is because, together, the two angles must add up to 90.
ANSWER:
D - (x + 15) + 48 = 90
Hope this helps!! :)

Answer:
x = 129
Step-by-step explanation:
x and 51 are same- side exterior angles and supplementary, thus
x = 180 - 51 = 129
