Solve y=f(x) for x. Then find the input when the output is −3. f(x)=−7x−2 x= The input is when the output is −3.

the answer is a.

step-by-step explanation:

in three games of golf, alex shot two under par four times.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
