Answer:

f(-3) = 21

g(3) = 69

Step-by-step explanation:

We have been given the following functions;

f(x) = –6x + 3

g(x) = 3x + 21x–3.

To find f(-3) , we simply substitute x = -3 in the function of f(x);

f(-3) = -6(-3) + 3

      = 21

To find g(3) , substitute x = 3 in the function of g(x);

g(3) = 3(3) +21(3) - 3

      = 69

A tennis racket at at sport city costs $180 and is discounted 15% the same model racket costs$200 at tennis world and is on sale
MaRussiya [10]
Mate, stop repeating questions, wait until your question has been answered.


15% of 180 is (180 * 0.15) = 27.

180 - 27 = $153 paid.


20% of 200 = (200 * 0.2) = 40.

200 - 40 = $160 paid.


Therefore Sport City offered the better deal.
