Answer:
(-10, 3)
Step-by-step explanation:
You can do it algebraically (substitution or elimination) or graphically. I will be using substitution to solve this.
Step 1: Rewrite 2nd equation
2y = 6
y = 3
Step 2: Plug in <em>y</em>
7x + 8(3) = -46
7x + 24 = -46
7x = -70
x = -10
Put it in coordinates and we have our final answer!
Answer:
y = 22.5x
worked 28 hours
Step-by-step explanation:
First find out what they make in 1 hour (rather than 40)
you can do this by 900 / 40 which gives you 22.5
this means for every hour worked, they get $22.50
so you can make the equation of y = 22.5x
try finding the hours worked by division
630/ 22.5 = 28
plug 28 into your equation to check
y = 22.5 ( 28 )
y = $630
hope this helps
