suppose you ca work a total of no more than 20 hours per week at your 2 jobs. babysitting $5 per hour, and your cashier job pays $6 per hour. you need to earn at least $90 per week to cover your expences. question : write a system of inequalities that showas the various numbers of hours you can work at each job. Graph the result. how do you do this??

Ax+By=C
A=5,
B=6,
C=90,
So, put in the numbers to variables:
5x+6y=90.
6y=905x
y=15*5over6*x
and then graph the line...
Hope I helped! :) good luck
