First replace y with 15.
1/5x-10=30
Then just solve from there.
x=200
H=number of hours
m=total salary
m=15.50h+50
put 400 in for m
400=15.50h+50
now solve for h
400=15.50h+50
-50. -50
350=15.50h
Divide 350 by 15.50to get your final answer
you get a long decimal so I rounded it.
22.6 hours
In y=x-4 your slope is 4.
In 2x+4=5 = 0.5
It’s the second option
sin(45)=13/x
8 x 6 = 42 add two zeros so 4200
