Step-by-step explanation:
factor out the negative signs
remove parenthesis
Answer:
x=3
Step-by-step explanation:
2x^2= 18
divide the two by 18 —- x^2=9
now x *x= 9 or the square root of 9
A: 2/1 -> 2
B: -1/1 -> -1
Gradient or slope is the change in the y value/change in the x value
Y value is up and down and x value is side to side.
Hope this helps! :)
-2x-8(-3+5)=-18
-2x+24-40=-18
-2x=-2
x=1
-2(1)-8y=-18
-2-8y=-18
-8y=-16
y=2
ANSWER:
x=1 y=2
3x^2 + 2x - 6 if x = -2
=3(-2)^2 + 2(-2) - 6
=12 - 4 - 6
= 2
5x^2 + 6x - 2 if x = -2
=5(-2)^2 + 6(-2) - 2
=20 - 12 - 2
= 6
-2x^3 + 2x^2 if x = 2
= -2(2)^3 + 2(2)^2
= -16 + 8
= -8
