Answer:
Translate ABCD down 1, then reflect it over the y-axis
and
Reflect ABCD over the y-axis, then translate down 1
Step-by-step explanation:
First of all, the two steps are the same, just in a different order
Second, if you look at the instructions you can see what would happen to the quadrilateral. Reflecting over the y-axis would make the shape flip horizontally (left to right), as shown in the image. This means the points on the left move to the right, and the points on the right move to the left. Top and bottom points stay the same. And the "translation" just means to slide. In both the answers, it says "translate 1 unit down", which just means "move 1 unit down", which is exactly what happens in the image
Answer
-4y+5
Explanation
You add -2y and -2y which equals -4y, then you add 12 and -7 which equals 5, then just put them in order as they appear in the equation.

Answer:
the missing value is 44
Step-by-step explanation:
let the missing value be x
we can solve this by expressing both ratios as rational expressions
11:4 = x:16
(cross multiply the denominators to eliminate them)
(11)(16) = (4)(x)
4x = 176
x = 176 / 4
x = 44
hence the ration is
11:4 = 44 : 16
