Answer:

y = 90

Step-by-step explanation:

A direct variation is

y = kx where k is a constant

30 = k(-3) from the first set of points

30/-3 = -3k/-3

-10 = k

The equation is y = -10x

Let x = -0

y = -10 * -9

y = 90

If mAD=85 degrees and mBC=31 degrees find the value

Eddi Din [679]

Answer: x = 11

To start, we know that a whole circle equals 360 degrees. If we subtract the 2 arcs we know, 85 and 31, we have 244 degrees left for the 2 congruent arcs. Dividing that by 2 gives us 122 for each arc.

Now, write the equation: 122 = 13x - 21

Solve this, to find the x = 11.
