I need help with please
Tcecarenko [31]

Answer:

x - 2

Step-by-step explanation:

2x - 1 + 4x - 11

First, you want to combine like terms.

We can see that the one and eleven can go together, so add them together.

2x + 4x - 12

The reason that we made one, and eleven, negative twelve, is because they are both being subtracted from the numbers before that.

6x - 12

We added the 2x, and the 4x together to make 6x.

Another way to write this would be x - 2, because you can simplify it by dividing it by 6.

The polygon Q(3, 2), R(6,5), S(6, 2)
ycow [4]

Answer:

Q' (12,8) , R'( 24,20) and S' (24,8)

Step-by-step explanation:

Here, we want to get the coordinates of the image after dilating the pre-image by a scale factor of 4

What we have to do here is to multiply each of the coordinate on the pre-image by 4

We have this as;

Q' = (4*3, 2 * 4) = (12,8)

R' = (4*6, 4*5) = (24,20)

s' = (4*6, 4*2) = (24,8)
