Answer:
x=(0.45,-4.45)
Step-by-step explanation:
x²+4x=2
x²+4x+(2)²=2+(2)²
x²+(2)²=2+4
(x+2)²=6
√(x+2)²√6
x+2=√6
x=-2±√6
x=-2±2.45
x=(0.45,-4.45)

Answer:
y=9-7x
If x= -1, y=16
If x= 0, y=9
If x=2, y= -5
Step-by-step explanation:
Because you are solving the equation for y, you want to have y by itself on one side. The only way to do that in this problem is by subtracting the 7x on both sides.
y+7x=9
-7x -7x ---> y=9-7x
The next part of the question says to find the value of Y for each value of X. Using the given X values, we plug them into the equation we just got in order to find Y.
y=9-7(-1) ----> y=16
y=9-7(0) ----> y=9
y=9-7(2) ----> y=-5
Answer: y=2/5x-8.7777....
