ABD = ABC + CBD
So 6x + 27 + 7x - 9 = 96
Now we need to isolate x
13x + 18 = 96
13x = 88
x = 6
And then apply x to the angle we need to find ( CBD )
CBD = 6x + 27
CBD = 6(6) + 27
CBD = 36 + 27 = 63
Angle CBD = 63°
The pricing scheme of the function is (a) The first two hours cost $2, between two hours and six hours cost $2 per hour, and all hours after that cost $1.
<h3>How to determine the pricing scheme?</h3>
The points are given as:
- Constant = (0,2) to (2, 2)
- Another = (2,2) to (6,10)
- Another = (6,10) to (7,11)
The constant interval implies that the first two hours cost $2
Next, we calculate the slope/rate of the other points.
This is done using
m = (y2 - y1)/(x2 - x1)
So, we have:
m1 = (10 - 2)/(6 - 2) = 2
m2 = (11 - 10)/(7 - 6) = 1
This means that:
- The next 4 hours are charged for $2 per hour
- All hours after that cost $1
Hence, the pricing scheme of the function is (a)

Answer:
K = 4/3 or 1 1/3
Step-by-step explanation:
4/3 or 1 1/3 - 2 is 2/3
2/3 times 9 is 6
Hope this helps ;)
Answer:
Option 2
Step-by-step explanation:
Answer:
Julio's number is 40.
Step-by-step explanation:
Solve:
(x - 19) * (-7) = -147
-7x + 133 = -147
-7x = -280
x = 40
Check:
40 - 19 = 21
21 * (-7) = -147
