Answer:
(2, -4)
Step-by-step explanation:
1/2 x + 3/4 y = -2
2/3 x + 5/6 y = -2
4 (1/2 x + 3/4 y = -2 ) = -2(2x + 3y = -8) Multiply by -2 to eliminate the x's
6 (2/3 x + 5/6 y = -2) = (4x + 5y = -12)
<u> -4x - 6y = 16 </u> combine with the 2nd equation
-1y = 4
y = -4
plug -4 in for y to find x in either equation
1/2x + 3/4 (-4) =-2
1/2x - 3 = -2
1/2x = 1
x = 2
(2, -4)
<h2>
Answer: d.) <u><em>
y=4x+16</em></u></h2>
Step-by-step explanation: <em>Let's solve for y.</em>
<em>−4x+y=16</em>
<em>Step 1: Add 4x to both sides.</em>
<em>−4x+y+4x=16+4x</em>
<em>y=4x+16</em>
You have a lot of questions here, I can help you with a few of them.
When you simplify the polynomials, you put together all of the terms that have the same degree. That means the variables have the same exponents. The number of terms are the items separated by plus and minus signs.
