Henry: 2.50r + 90 = Earnings
Yolanda: 5.25r + 75 = Earnings
Where r is the number of repairs performed.
H=-16t^2+49
find where h=0
0=49-16t^2
0=7^2-(4t)^2
difference of 2 perfect square
0=(7-4t)(7+4t)
set to zero
7-4t=0
7=4t
7/4=t
7+4t=0
4t=-7
t=-7/4
faslse, this is before the person jumps
answer is 7/4 seconds

Answer:
F. x ≤ -5
Step-by-step explanation:
Translating the diagram to more conventional symbols, we have ...
4x +12 ≤ -8
4x ≤ -20 . . . . . . . subtract 12 from both sides
x ≤ -5 . . . . . . . . . divide both sides by 5
Answer: Third degree polynomials are also known as cubic polynomials. Cubics have these characteristics: One to three roots. Two or zero extrema.
