X = rate of mechanic who worked 5 hours
y = rate of mechanic who worked 15 hours
x + y = 200
5x + 15y = 1950
you find the first variable in one of the equations, then subsitute the result into the other equation. your answer would be:
the mechanic who worked for 5 hours charged $105 per hour, the one who worked 15 hours charged $95 per hour.

Answer:
h(-4) =101
Step-by-step explanation:
H(x) = 6x ^2 +5
We have to find when h=4, putting it into function
h(-4) = 6(-4) ^2 +5
h(-4) = 6(16) +5
h(-4) = 96 +5
h(-4) =101
23 or 23/1 or 23.0
