Answer:
+ 1
Step-by-step explanation:
Given
x² + 2x = 9
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1² = 9 + 1²
(x + 1)² = 10
Answer: x = -3.625 or -29/8
Step-by-step explanation:
7-8x+22
1. -Set it equal to 0.
7-8x+22=0
2. Subtract 7 and 22 from both the left and right sides.
7-8x+22=0
-7 -22 -7 -22
8x = -29
4. Divide both sides by 8.
8x=-29
8 8
x= -3.625
Leave it in fraction form if decimal is unacceptable.
hope this helps.
(4+2)/(1+1)= 6/2= 3 is the slope
y + 2 = 3(x + 1)
y+2=3x+3
y= 3x+1

Answer:
it si this
Step-by-step explanation:
Simplifying
4y + -10 = 5 + -1y
Reorder the terms:
-10 + 4y = 5 + -1y
Solving
-10 + 4y = 5 + -1y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add 'y' to each side of the equation.
-10 + 4y + y = 5 + -1y + y
Combine like terms: 4y + y = 5y
-10 + 5y = 5 + -1y + y
Combine like terms: -1y + y = 0
-10 + 5y = 5 + 0
-10 + 5y = 5
Add '10' to each side of the equation.
-10 + 10 + 5y = 5 + 10
Combine like terms: -10 + 10 = 0
0 + 5y = 5 + 10
5y = 5 + 10
Combine like terms: 5 + 10 = 15
5y = 15
Divide each side by '5'.
y = 3
Simplifying
y = 3
