Answer:
one solution: x = -3, y = 26
Step-by-step explanation:
3x + y = 17
x + 2y = 49
If you multiply the first equation by -2 and then add you will eliminate the 'y' term
-2(3x + y) = -2(17)
-6x - 2y = -34
<u>+ x + 2y = 49</u>
-5x = 15
x = -3
-3 + 2y = 49
2y = 52
y = 26
The answer is c.
<span>The slope formula can be used to prove a quadrilateral has parallel sides. This is made obvious when we remember that parallel lines have the same slopes.

Answer:
x=60
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
40+80+x = 180
Combine like terms
120+x =180
Subtract 120 from each side
120-120+x = 180-120
x = 60
