Question

If f(x)= 10 – 2x and g(x) = 6x - 5, then (f+g)(x) =

Answer 1

( f + g )( x ) = 4 x + 5

Explanation:

f ( x ) = 10 - 2 x

g ( x ) = 6 x - 5

( f + g )( x) = ( (10 - 2 x ) + (6 x -5) )

= 10 - 2x + 6 x - 5

combine like terms

= 2 x + 6 x + 10 - 5

= 4 x + 5

Answer 2

4x +5

Explanation:

f(x)= 10 – 2x

g(x) = 6x - 5

(f+g)(x) =10 – 2x + 6x - 5

Combine like terms

= 4x +5
