Answer:
10 i think
Step-by-step explanation:
Remember that percent means parts out of 100 so
x%=x/100
the easier way is to convert fractions to percent by making the bottom number 100 so
4/5 times 20/20=80/100=80%
so the equation is really
-80%-137.5%-20%=-237.5%
F(n)=9n
f(10)=9(10)
f(10)=90
f(10)=90 means that when you work 10 hours your gross pay is $90.
Answer:
(-2, 3)
Step-by-step explanation:
In the form ...
y -k = a(x -h)^2
the vertex is (h, k).
Your equation has k = 3, a = -1, h = -2, so the vertex is ...
(h, k) = (-2, 3)
10.5
0.475 / .045 = 10.5
I hope this helped
