Question

Can you guys plz help me?

Answer 1

F(x) = 13x + 52

14) games leon must play to score fewer than 182 points

182 > 13x + 52
-52            - 52
130 > 13x
÷13     ÷13
  10 > x  *leon must play 9 games or less to score fewer than 182 points.

to check: x = 9 ; 182 > 13(9) + 52 ⇒ 182 > 117 + 52 ⇒ 182 > 169

15) games leon must play to score more than 143 points
143 < 13x + 52
 -52           - 52
91   < 13x
÷13    ÷13
   7  < x     * leon should play 8 games or more to score more than 143 points.

to check: x = 8 ; 143 < 13(8) + 52 ⇒ 143 < 104 + 52 ⇒ 143 < 156
