Answer:
yes
Step-by-step explanation:
Substitute x = - 3 and y = 2 into the left side of the inequality and compare the value obtained with the right side.
- 3 - 5(2) = - 3 - 10 = - 13 < 7
Thus (- 3, 2) is a solution of the inequality
Y=x² +14x +48
y-48 = x² +14x
y-48+7² = x² +2*7*x +7²
y-48+49 = (x+7)²
y+1= (x+7)²
y=(x+7)² - 1
Vertex of the function is (-7,-1). Minimum value of this function is a vertex value , because parabola directed up.
Joe is at most 20 and Bill would be at most 27 because it has to be less than 49 combined
