<u>Answer:</u>
Second option
<u>Explanation:</u>
The inverse of a graph is its reflection on the line y = x.
This means it is the graph that you get by reflecting the original graph on a line with the equation y = x.
In the picture below, you can see a function (red graph), its inverse (blue graph) and the line (green) that the two graphs are reflected on.
Multiply 340 by 20%
first change 20% into a decimal which is 0.2
340*0.2 = 68
so it decreased by 68.
Answer:
15 metres
Step-by-step explanation:
perimeter of rectangle = 2(base + height)
=2(8+h) = 46
= 16 + 2h = 46
= 2h = 46 - 16
= 2h = 30
= h = 15
15 metres is the height of rectangle

Answers:
- Part A) There is one pair of parallel sides
- Part B) (-3, -5/2) and (-1/2, 5/2)
====================================================
Explanation:
Part A
By definition, a trapezoid has exactly one pair of parallel sides. The other opposite sides aren't parallel. In this case, we'd need to prove that PQ is parallel to RS by seeing if the slopes are the same or not. Parallel lines have equal slopes.
------------------------
Part B
The midsegment has both endpoints as the midpoints of the non-parallel sides.
The midpoint of segment PS is found by adding the corresponding coordinates and dividing by 2.
x coord = (x1+x2)/2 = (-4+(-2))/2 = -6/2 = -3
y coord = (y1+y2)/2 = (-1+(-4))/2 = -5/2
The midpoint of segment PS is (-3, -5/2)
Repeat those steps to find the midpoint of QR
x coord = (x1+x2)/2 = (-2+1)/2 = -1/2
y coord = (x1+x2)/2 = (3+2)/2 = 5/2
The midpoint of QR is (-1/2, 5/2)
Join these midpoints up to form the midsegment. The midsegment is parallel to PQ and RS.
