Answer:
P' = (2, -2)
Step-by-step explanation:
You have the x-value and the y-value of the pre-image, so all you have to do is plug that into the translation statement (x + 9 , y - 3).
Since x = -7 and y = 1 that would be (-7 + 9, 1 - 3), or (2, -2).
Answer:
Now we can solve a Quadratic Equation in 5 steps: Step 1 Divide all terms by a (the coefficient of x 2). Step 2 Move the number term (c/a) to the right side of the equation. Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.
Step-by-step explanation:
Answer:
x = 
Step-by-step explanation:
Given
+ x - 
= 
Multiply through by 14 to clear the fractions
2x + 14x - 2 = 2 ( add 2 to both sides )
16x = 4 ( divide both sides by 16 )
x = 
=
3.25 + (3.25 + 5.20)
3.25 + 8.45
11.70
If you would like to find the value of x, you can do this using the following steps:
22x - y = -23 ... 22x = y - 23 ... x = (y - 23) / 22
11x + 12y = 1
___________________
11 * (y - 23) / 22 + 12y = 1
(y - 23) / 2 + 12y = 1
y - 23 + 24y = 2
25y = 2 + 23
25y = 25
y = 1
x = (y - 23) / 22 = (1 - 23<span>) / 22 = - 22 / 22 = - 1

The correct result would be: x = -1, y = 1.
