Does anyone know the answer
lesya [120]
If the square translates to 7 units on the right and 6 units downwards, the following changes will be made:
 
Point S will have the coordinates of (3, -5).

Point R will have the coordinates of (-1, -5).

Point U will have the coordinates of (-1, -9).

Point  T will have the coordinates of (3, -9).

According to the only answer choices in the picture, only (-5, -3) is the only point that lies on a side of the pre-image, square RSTU.

7(x+2)=2x-1 solve for the variable
Len [333]

Answer:

x = - 3

Step-by-step explanation:

Given

7(x + 2) = 2x - 1 ← distribute parenthesis on left side

7x + 14 = 2x - 1 ( subtract 2x from both sides )

5x + 14 = - 1 ( subtract 14 from both sides )

5x = - 15 ( divide both sides by 5 )

x = - 3
