Answer:
see below
Step-by-step explanation:
A. Reflection across the y-axis replaces each x coordinate with its opposite.
B. Rotation 90° CW does the transformation (x, y) ⇒ (y, -x)
C. This is a translation left 2 units.
D. Rotation 90° CCW does the transformation (x, y) ⇒ (-y, x)
E. This is a translation left 7 and down 2.

In the attached graphs, we have identified a point that is a corresponding point on each figure. This is so you can see how the various transformations move it and the rest of the figure in relation to it. 90° arcs are shown so you can see the rotations more easily.
The figures are labeled and color coded in accordance with the problem statement.
X = 3
y = -3
You will see this using any graphing tool at your disposal.
Answer:
A) -4x + 9y = 9
B) x -3y = -6
We multiply B) by 3
B) 3x -9y = -18 Then add it to A)
A) -4x + 9y = 9
-x = -9
x = 9
9 -3y = -6
3y = 15
y = 5

Answer: 1 13/30 hrs left
Step-by-step explanation:
his class lasts 2 5/6 hrs...and he has already been in there for 1 2/5 hr
so the time he has left can be found by subtracting the time he has been there from the total time of the class
2 5/6 - 1 2/5....
(2 - 1) = 1 : (5/6 - 2/5 = 25/30 - 12/30 = 13/30)
so he has 1 13/30 hrs left
Its an isosceles triangle because there are two sides that are the same length
