Answer:
<u>Y is the midpoint of XZ, so XY = YZ</u>
- 20x - 30 = 12x + 10
- 20x - 12x = 10 + 30
- 8x = 40
- x = 5
<u>Find XZ:</u>
- XZ = 2(XY) = 2(20*5 - 30) = 140
<u>The answer is: </u>
------------------------
<u>B is the midpoint of AC, so AB = BC</u>
- 4x + 3 = 2x + 15
- 4x - 2x = 15 - 3
- 2x = 12
- x = 6
<u>Find AC:</u>
- AC = 2(AB) = 2(4*6 + 3) = 54
<u>The answer is:</u>

Answer:
Option D 
Step-by-step explanation:
In this problem we have a exponential function of the form
where
F(x) -----> the rabbit population
x ----> the number of weeks
a is the initial value
b is the base
In this problem we have
a=150 rabbits
b=1-r
r=15%=15/100=0.15
so
b=1-0.15=0.85
substitute the values

Answer:
=35
Step-by-step explanation:
3(3) ^2 + 2(4)
= 3(9) + 8
= 35
Where you see a, substitute with 3 and where you see b, substitute with 4
Just follow the steps above.
Answer:
x=8
Step-by-step explanation:
Those angles are supplementary so:
140+5x=180
5x=40
x=8
