Question 1)
Given
f(x) = -2x+17
g(x) = -5x-10
To determine
h(x) = f(x) – g(x)
Using the equation
h(x) = f(x) – g(x)
substitute f(x) = -2x+17 and g(x) = -5x-10
= -2x+17 - (-5x-10)
= -2x+17 + 5x + 10
= 3x + 27
Thus,
h(x) = 3x + 27
Question 2)
Given
f(x) = 7x+6
g(x) = 6x+8
To determine
j(x) = f(x) + g(x)
Using the equation
j(x) = f(x) + g(x)
substitute f(x) = 7x+6 and g(x) = 6x+8
j(x) = 7x+6 + 6x+8
j(x) = 13x + 14
Thus,
j(x) = 13x + 14
