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

Part A number of combinations of 8 from 10 = 10C8 = 10C2
= 10*9 / 2 = 45
Part B Number combinations = 10C4 = (10*9*8*7)/ (4*3*2) = 210
Total number of ways = 45 * 210 = 9450 (answer)

Step-by-step explanation: 144*20=2880 calories.
Given two numbers 0.67 and 0.6, the difference between the two is 0.07.
This implies that 0.67 > 0.6
Answer:
(x,y ) = ( - 2,3)
