An image point has coordinates B'(7, -4). Find the coordinates of its pre-image if the translation used was (x + 4, y + 5).

Vera_Pavlovna [14]

Answer:

Step-by-step explanation:

B'(7, -4)

Let the pre-image coordinates be (x,y)

Consider x-coordinate,

x + 4 = 7

x = 3

Consider y-coordinates,

y + 5 = -4

y = -9

pre-image coordinates is (3, -9)

8(3)-3y=12 <br> What is y in this equation

iVinArrow [24]

8(3) - 3y = 12

First, multiply 8 × 3 to get 24.
$24 - 3y = 12$
Second, subtract '24' from both sides.
$-3y = 12 - 24$
Third, subtract '12 - 24' to get '-12'.
$-3y = -12$
Fourth, divide both sides by '-3'.
$y = \frac{-12}{-3}$
Fifth, change the whole fraction to a negative.
$y = \frac{12}{3}$
Sixth, 12 ÷ 3 = 4. Simplify your fraction to 4.
$y = 4$

Answer: y = 4
