m cm3
n= cm2df
Step-by-step explanation:
1. y= -x + 3
2. y = x - 3

Answer:
$3.97
Step-by-step explanation:
Three containers @$2.98 = 3 × 2.98 = $8.94
Less $1 = <u>-1.00
</u>
7.94
Less 50% paid my mom = ½ × 7.94 = <u>-3.97
</u>
Paid by Theresa = $3.97
[(3 × 2.98) - 1] ÷ 2 = (8.94 - 1) ÷ 2 = 7.94 ÷ 2 = 3.97
Multiply the first equation by 2
4x-6y=16
Then add the equations to eliminate x
4x-6y=16
-4x+5y=-10
-y=6
y-=6
Plug the y value in
2x-3(-6)=8
2x+18=8
2x=-10
x=-5
Final answer: (-5,-6)
