Answer:
3
Step-by-step explanation:
Inverse functions "undo" each other. f(g(3)) = 3, the number you start with.
To see this in the context of this problem...
g(3) = 3/5, f(g(3)) = f( 3/5 ) = 5(3/5) = 15/5 = 3.
g changes the input 3 to its output 3/5. f changes input 3/5 back to the original value 3

Answer:
14.28 < h < 15
She can and would need to work 14.28 hours.
Step-by-step explanation:
To find how many hours she needs to work to earn $100, we need to know how much she is paid per hour. This amount is x because it is unknown. So 12 hours at x rate equals 84. This is 12x=84 so x=$7 per hour.
To earn a 100, she will earn $7 a hour but not work more than 15 hours. So we write the equation 100=7h where h is number of hours. Solve and h = 14.28. So Sylvia must work 14.28 < h < 15 to earn 100.
Answer:
(z-9)(z+2)
Step-by-step explanation:
U have to find numbers which when u multiply u get -18 and subtract u get -7
-18= -9×+2,2-9=-7
Z²+2z-9z-18
Z(z+2)-9(z+2)
(Z-9)(z+2)
