Answer:
Commutative Property of Addition
y = -2x - 3
Step-by-step explanation:
-solve for y: y = 1/2x + 2
-perpendicular equals opposite slope: -2
-plug in the point: (1) = -2(-2) + b
1 = 4 + b
b = -3
put it all together: y = -2x - 3
Answer:5
ok
Question 1 Answer : x^2 - 2y^2
Question 2 Answer: x^2 - 36
x=0
combine like terms on both sides of the equal sign
-9+x= x-7
move similar terms to the same side
-2=0x
divide both sides by x
