Answer:
I could do 1 and 3
1) 2x-3y=-2 ....1
-
2x+y=14......2
=-4y=-16
y=4
<u>Substitute</u><u> </u><u>(</u><u>y</u><u>=</u><u>4</u><u>)</u><u> </u><u>into</u><u> </u><u>equation</u><u> </u><u>1</u>
2x-3 (4)=-2
2x-12=-2
2x=-2+12
2x=10
×=5
3) 5x+5y=20....1
-
-3x+5y=4......2
=8x=16
x=2
<u>S</u><u>ubstitute</u><u> </u><u>(</u><u>x</u><u>=</u><u>2</u><u>)</u><u> </u><u>into</u><u> </u><u>equation</u><u> </u><u>1</u>
<u>5</u><u> </u><u>(</u><u>2</u><u>)</u><u>+</u><u>5y</u><u>=</u><u>20</u>
<u>10</u><u>+</u><u>5y</u><u>=</u><u>20</u>
<u>5y</u><u>=</u><u>20-10</u>
<u>5y</u><u>=</u><u>10</u>
<u>y</u><u>=</u><u>2</u>

Answer:
(x,y)=(2,12).
Step-by-step explanation:
Let's find the answer using the given equations:
y1=5x+2
y2=-3x+18
Using the intersection method:
y1=y2 so:
5x+2=-3x+18
5x+3x=18-2
x=16/8=2
Using x=2 in the first equation we have:
y1=5*(2)+2=12
So, the answer is (x,y)=(2,12).
Let's check our answer:
y1=5x+2
12=5*(2)+2
12=12
y2=-3x+18
12=-3*(2)+18
12=12
A.2 but it could also be 4 but its not one of the answers...
I would say linear because it fits those requirements. An example of a linear equation could be y= x +1 and the variable is raised to the first power so it is its own self, it's variable is not in the denominator, absolute value symbol, nor a square root symbol.
