The angles of a parallelogram add up to 360°
and the opposite angles are equal
so you make the equation: 150+150+5x+5x=360
you solve for x
10x=60
x=6
8 more that is 8+
four times a number is 4*X
is -12: =-12
8+4*X=-12
to solve this equation subtract 8 from both sides.
8+4*X=-12
-8 -8
4*X=-20
divide by 4 on both sides.
X=-5
Answer:
because in the bottom eqution it shows us x-3=y therefor we could re-write the top equation as x+x-3=11
Answer:
yes it is a function it passes the vertical line test
