Answer:
A'=(3,-2) B'=(-1,-4) C'=(-5,-3)
Step-by-step explanation:
90 degrees counterclockwise uses (-y,x) so you just plug in the negative y value in the x spot and the x value in the y spot
From 10:00 am I would be 11 hours
Let's say the number is represented by x.
Five times the number is 5x.
5x - 58 = -23 (Add 58 to both sides)
5x = 35 (divide both sides by 5)
x = 7
The number is 7.
