8x + 42 = 90
8x = 90 - 42 = 48
x = 48/8 = 6 answer
Answer:
For 100 calls the monthly cost = 10.95 + 0.95(100) = $ 22.95
120 calls = 10.95 + 0.95(120) = $ 25.35
140 calls = 10.95 + 0.95(140) = $ 27.75
160 calls = 10.95 + 0.95(160) = $ 30.15
Therefore it is constant
The answer is B. Yes, the average rate of change is constant

Factors of -8 that add up to 2: 4 & -2
(x + 4)(x - 2)
Set x to 0 for both and solve
x = -4
x = 2
Answer:
Measure of angle O is 56 degrees.
Step-by-step explanation:
We can see from diagram that NQ is minor arc and NRQ is major arc. Our angle R (inscribed angle) and O (central angle) are corresponding to minor arc NQ. We will use inscribed angle theorem which states that measure of inscribed angle is one-half the measure of central angle.
We are given that measure of inscribed angle R is 28 degrees. To find measure of our central angle O we will multiply 28 by 2.

Therefore, measure of angle O will be 56 degrees.
