1. If f(x) = 5x – 8 and g(x) = 2x +4, which of the following represents the simplified form of (f + g)(x)? a. (f + g)(x) = 3x - 4
b. (f+g)(x) = 7x + 4
c. (f+g)(x) = 7x - 4
d. (f + g)(x) = 3x + 4

-6 is the correct option from the above given options

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
