The coordinate A(-1, 1) reflected over y-axis is (1, 1) is the coordinate of E, hence the two figures are congruent
- The given figures are quadrilaterals, in order to determine whether they are similar, we need to check if they are reflections of each other.
- For the Quadrilateral ABCD, the coordinate of A is at A(-1, 1) and for the Quadrilateral DEFG, the coordinate of E is at E(1, 1).
- Note that if an object is reflected over the y-axis the transformation is (x, y)->(-x, y)
- We need to check whether if we reflect the coordinate A over the y-axis we will get coordinate E
Since the coordinate A(-1, 1) reflected over y-axis is (1, 1) is the coordinate of E, hence the two figures are congruent

Answer:
120
equation: 40+8(10)=120
Step-by-step explanation:
The math for this is $40 initial plus $8x the 10 weeks which equals 80 so
40+80=120
Quadrant 2.
This is because the x-value is negative, and therefore is on the left side of the axis; and the y-value is positive, and therefore is on the top side of the axis. Putting this together, we find that (-2.7) is in Quadrant 2.
3x ≤ 5y - 10
3x - 5y ≤ 5y - 5y - 10
3x - 3x - 5y ≤ -3x - 10
-5y ≤ -3x - 10

y ≥ ³/₅x + 2
2x - 4y < -6
