After trying to do it the hard way, i remembered the easy way.
substitution:
because x = 6 and 6 is in the range of -6 < x < 9, we only need the equation 6x^(2) + 2
f(x) = 6x^(2) + 2
f(6) = 6(6)^(2) + 2
f(6) = 6(36) + 2
f(6) = 216 + 2
f(6) = 218
Answer:
187
Step-by-step explanation:
Were gonna start by writing an equation (139+184+x)/3=170 because were adding a 3rd value to the average and x is going to be our value that were looking for. If you solve that, you get 187. Hope this helps.
