Solve for y
eliminate x
multiply firs tequation by -5 and 2nd by 3 and add them
-15x-30y=-15
<u>15x-3y=81 +</u>
0x-33y=66
-33y=66
divide both sides by -33
y=-2
the y coordinate is y=-2
Answer:
YES
Step-by-step explanation:
Most real numbers (points on the number-line) are irrational (not rational). The rational numbers are those which have repeating decimal expansions (for example 1/11=0.09090909..., and 1=1.000000...=0.999999...) . They are also those which have terminating continued fraction expansions.
P = 8 + 10 + 8 + 10
P = 36

-52
Step-by-step explanation:
-18+6=-12
-12-40=-52
Answer:
2y + 2x = 0
Step-by-step explanation:
First you have to find the slope of the line.
Parallel lines have same slope
2y = -2-2x
y=-1-1x, y=-1x-1
slope = -1
Use point slope formula
y-y=m(x-x)
y-(-9) = -1(x-9)
y+9 = -1(x-9)
y+9 = -1x+9
y = -x
y + x = 0
2y + 2x = 0
