Alternate interior angles means the angles across from another are equal. If you follow the line up 85 is directly across from 2x+1
then you can say
85 = 2x +1
85 -1 = 2x
84 = 2x
84/2 = x
42 = x
supplementary angles make a straight line so they must add to equal 180 degrees.
That means the other angle 3y+5 = 180-85
3y +5 = 95
3y = 95-5
3y = 90
y = 90/3
y = 30
Answer:
8.
<u>9y-3y=6</u>
-4x-(-5x)=1
the slope is 6
9.
you start at the 0 axis and go up 3 on the y.Once you did that you want to go up 2 on the y axis then 3 to the right on the x axis,then go up 2 then 3 to the right.

Answer:
1 and 11/20
Step-by-step explanation:
3/4 + 4/5
= 15/20 + 16/20
= 31/20
= 1 and 11/20
Hope this helped!
Answer:
Step-by-step explanation:
%change=100(final-initial)/(initial)
%change=100(26-20)/20
%change=30%
Since this is positive the number of dogs increased by 30%
Answer:
In general you can choose the vertices at any arbitrary points but for easier computations and calculations we can choose 1 vertex at origin with co-ordinates and it's adjacent vertex either on x-axis with co-ordinates or on y-axis with ordinates
Thus the coordinates of vertices become
