[what is 3x]=9because I really dint know can you help me

X=3

Step-by-step explanation:

9 divided by 3 (which comes from 3x) equals 3

X= 3

x=3

Step-by-step explanation:

To isolate x, just divide 3 on both sides. The 3's will cancel out, so your left with 9/3 on the right. 9 divided by 3 is 3.

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)
