Answer:
ABCD→ Reflection across the x- and y-axis in any order; WXYZ→Translation 3 units left and 3 units down; OPQR→Translation 2 units right and 3 units down; EFGH→Translation 3 units left and 2 units up.
Explanation:
Comparing ABCD to JKLM, we see that the coordinates are negated. This means that, since both have been negated, there has been a reflection through the x-axis, which negates the y-coordinate, and through the y-axis, which negates the x-coordinate.
Comparing WXYZ to JKLM, we see that the x-coordinate is 3 less in JKLM and the y-coordinate is 3 less in JKLM. This means it is a translation 3 units left and 3 units down.
Comparing OPQR to JKLM, we see that the x-coordinate is 2 greater in JKLM and the y-coordinate is 3 less in JKLM. This means it is a translation 2 units left and 3 units down.
Comparing EFGH to JKLM, we see that the x-coordinate is 3 units less in JKLM and the y-coordinate is 2 greater in JKLM. This means that it is a translation 3 units left and 2 units up.
Answer:
x=KY
as x is directly proportional to y
2,3 I think that’s the answer

Answer:
18: x=98 y=38
19: x=20 y=50
Step-by-step explanation:
To figure out figure 18 you would first figure out x and a triangle equals 180 so 180- (36+46) which is 180-82= 98 and then there are vertical angles between the right and left side so x is equal to one of the angles on the right so 98+44= 142 and 180-142= 38
Then to figure out figure 19 you would first find y by adding 39 and 91 to get 130 and 180-130=50 and then 180-91 (for the angle in the bottom right for the left triangle) is 89 so 89+71=160 and 180-160 is 20.
