Answer:
3+(-4) i think is the answer.
Step-by-step explanation:
since the bottom line is faceing toward the positve numbers that number its representing will be a positve, and since all the answers start with 3, three will be the first number. Same thing with the bottom line, its facing toward the negative numbers so itll be negative, just count the lines under it and theres the second number in the equation.
hope this helps.
Your scaling in the x direction is OK, but you didn't scale in the y direction properly. Hint. Scale each vertex of the original rectangle independently to construct the scaled rectangle.
I see the original points and their scaling by 2 as
(2,2) - Scales to (2*2, 2*2) = (4,4) OK in your drawing.
(-2,2) - Scales to (-2*2, 2*2) = (-4,4) OK in your drawing.
(2,5) - Scales to (2*2, 5*2) = (4,10) Error in your drawing.
(-2,5) - Scales to (-2*2, 5*2) = (-4,10) Error in your drawing.
A 2x -7 sorry about the other person I reported their answer
