The expression is equivalent to r^(m-n)
Answer:
14
Step-by-step explanation:
From the given information:
suppose, Y is the number of times a coin is being flipped.
If the coin is flipped for the first time and we get H, then we have:
TTT = 
Afterward, if we get H, then we waste two times plus the probability of this event
.
Therefore, we have : 
Afterward, if we get H, then we waste three times plus the probability of this event
.
Therefore, we have : 
If we got T at the third time, then;
T = 
Thus, average number of headsthat you’ll see until gettingTTT can be expressed as:

= 14
Answer:
The length of BC is 17
Step-by-step explanation:
When we construct a triangle with the data, we will end up a isosceles triangle.
In a isosceles triangle , we know that tow angles and two sides are equal
The questions states that

Then sides AC and AB are also equal
On equation their values
2X - 8 = X+9
2X = X + 9 +8
2X = X + 17
2X - X = 17
X = 17
The length of BC = X = 17
Written in slope intercept form y=mx+b.......m is the slope.......b is the y intercept or where the line crosses the y axis
y=-2/3x - 4
Answer:
A
