Given f (x) = 10 minus 2 x, find f(7).

f(7) = - 4

Step-by-step explanation:

To evaluate f(7) substitute x = 7 into f(x)

f(7) = 10 - 2(7) = 10 - 14 = - 4

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°

i think it might be a but you might want a second opinion
