If f(x) = 7x - 5, what is the value of f(5) and (f8)?
If f(x) = x^2, find the value of [f(a+h)-f(a)]/h.
If f(x+3 ) = f(x) + f(3), show that i) f(0) = 0 ii) f(-3) = -f(3)
If f(4x) = f(4) + f(x), show that i) f(4) = 0 ii) f(16) = 0

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

the correct answer is 1: 2

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
