Answer:
negative
Step-by-step explanation:
Answer:
2 hours.
Step-by-step explanation:
Money earned for 14 hours of life-guarding = 14*18 = $252. If he worked another 5 hours to make the maximum of 19 he would earn 252 + 5*9
= $297 but he wants to work a minimum of hours for a minimum of 270.
Thus we have the inequality:
252 + 9x ≤ 270
9x ≤ 18
x ≤ 2.
So the number of hours he must do clearing tables = 2.
If x=-4, that means that since we have x² at x≤-4, it encompasses -4 (due to the line at the bottom). (-4)²=16. For 4, since 4>1 and it's √x if x is over 1, √4=2
