Answer:
-2x² + 15
Step-by-step explanation:
Step 1: Add like terms
4x² - 6x² = -2x²
-10x + 10x = 0
3 + 12 = 15
Step 2: Rewrite
-2x² + 15
Y=x-4
x=y+4
y=-3(y+4)
y=-3y-12
4y=-12
y=-3
x=1
11/2 / 3 = 11/6 pounds per friend
divide 11/2 pounds by 3 in order to get answer
If we're talking in whole numbers, the only multiplication of whole numbers that equals two is
2 * 1
or
-2 * -1
Here's y
y=<span><span><span><span>−<span>8x</span></span>+29
</span><span><span>−x</span>+<span>3
Hope this helps:)
