Use substitution to determine whether the value for x is a solution for the equation. 3x + 10 = 25 x = 5 5x − 10 = 25 x = 6 6x − 18 = 6 x = 4 4x + 12 = 40 x = 7 8x + 12 = 28 x = 3

3x + 10 = 25   x = 5

4x + 12 = 40  x =7

Step-by-step explanation:

5x − 10 = 25 x =7

8x + 12 = 28  x = 2

the co-ordinates of the transformed rectangle are:

d. (0, 0), (0, 3), (-3, 3), (-3, 0)

step-by-step explanation:

from the columns of the given matrix, the co-ordinates of the rectangle before transformation are:

(0, 0), (0, 3), (3, 3), (3, 0)

r =

transformed matrix can be obtained by multiplying the given matrix by r:

columns of the transformed matrix are:

0   0   -3   -3

0   3     3     0

from the columns of the resulted matrix, we can see that the vertices of the transformed triangle are:

(0, 0), (0, 3), (-3, 3), (-3, 0)

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
