I think I might be wrong but try 25% (but like I said probably wrong)
80 / 100 = 1.25
100 - 80 = 20
So, 1.25 x 20 = 25%
Answer:
k = ½
Equation => 
Step-by-step explanation:
Constant of proportionality (k) = y/x
Using a point on the graph, (6, 3),
k = y/x = 3/6 = ½
k = ½
Equation of the line:
Plug in the value of k into
(slope-intercept form of equation for proportional relationship)
Thus:

Answer: Choice D
Explanation:
I'll use the point-slope form to get the following

You should find that plugging x = -4 into equation D will lead to y = 1 as a way to confirm the answer.
Answer:
B
Step-by-step explanation:
The triangle UVW is similar (or congruent) to the triangle XZY.
U angle of the triangle UVW = 36 degrees
X angle = 180 - 72 - 72 = 36 degrees
Therefore:
V angle = Z angle = 72 degrees
W angle = Y angle = 72 degrees
Triangle UVW is a isosceles triangle at angle U.
=> UV = UW = 5.7 cm
=> the perimeter of triangle UVW = the perimeter of triangle XZY = 5.7 x 2 + 3.7 = 15.1 cm
Answer: A) y = -4
<u>Step-by-step explanation:</u>
The midline is usually at y = 0. In the given equation, the graph is shifted down 4 units so the new midline is at -4.
