Answer:
midpoint = (-6,2)
Step-by-step explanation:
Use the midpoint formulas.
-8 + (-4) = -12/2 = -6
-6 + 10 = 4/2 = 2
In a circle, the degree measure of an arc is the same as the measure of the central angle that intercepts it.
A full circle is 360 degrees.
Add all the measures and set equal to 360 degrees.
One angle measure is not given, but that angle has a mark and another angle has the same mark, so the angle whose measure is not give also measures -9x - 3.
-9x - 3 + x + 107 + (-6x + 8) + (-9x - 3) + (-13x - 1) = 360
-9x - 3 + x + 107 - 6x + 8 - 9x - 3 - 13x - 1 = 360
-36x + 108 = 360
-36x = 252
x = 252/(-36)
x = -7
Answer:
Step-by-step explanation:
a)
b)
Rationnel roots are divisor of -2: -1,1,-2,2
c) see picture
For the first one it would be (5,8) and for the second graph it would be (-8,8)
