3.45- 1.23= 2.22
2.22-.85=1.37
molly walked 1.37 miles farther
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

Step-by-step explanation:
Let r represent the number of rabbits the farmer has. Then 45-r is the number of chickens. The total number of legs is then ...
4r +2(45-r) = 140
r +45 = 70 . . . . . . . . divide by 2 and simplify
r = 25 . . . . . . . . . the number of rabbits
45 -r = 20 . . . . . the number of chickens
The farmer has 20 chickens, and 25 rabbits.
Answer:
H = cg The number of calories to melt one gram is the constant of proportionality. Heat = calories(mass) Write as y = kx, where k is the constant of proportionality → H = cg → c is the constant of proportionality
