Answer:
f(x) + g(x) = (-2x + 8)+ 3x
f(x) + g(x) = -2x + 8 + 3x Combine like terms.
f(x) + g(x) = x + 8
f(x) + g(x) = (f+g)(x) = x + 8
(f + g)(-1) = -1 + 8
(f + g)(-1) = 7
Step-by-step explanation:
Answer:
y-axis is x = 0
Step-by-step explanation:
if P(x, y) is any point on AB, then x = a. Hence, the equation of a straight line parallel to the y-axis at a distance from it is x = a. The equation of the y-axis is x = 0, since, the y-axis is parallel to itself at a distance 0 from it.
