Let H = number of hours worked.
He gets $15 for every hour worked, so you need to multiply 15 by h which is written as 15h
You then need to add that to the $200 he gets for showing up.
Total pay = 15h + 200
Question a:
f(6) = (6)² + 2(6) + 8
f(6) = 36 + 12 + 8
f(6) = 56
Question b:
f(x+4) = (x+4)² + 2(x+4) + 8
f(x+4) = x² + 8x + 16 + 2x + 8 + 8
f(x+4) = x² + 10x + 32
Question c:
f(-x) = (-x)² + 2(-x) + 8
f(-x) = x - 2x + 8
Since each basket in basketball is 2 points, then 2 * 5 = 10. If Cathy makes 6 more points from free throws, which are each one point, then you would have to do 10 + 6, which equals 16. So in total, Cathy scored a total of 16 points.
2/7 = x/10
cross multiply:
10 * 2 = 20
7 * x = 7x
7x = 20
x = 2.857
