did you get it ?
Step-by-step explanation:
Answer:
Step-by-step explanation:
average of x-coordinates = (-4+2)/2 = -1
average of y-coordinates = (11+3)/2 = 7
midpoint of AB = (-1,7)
Answer:
D. 4
Step-by-step explanation:
Without actually solving the equation, recall that for 
, there are two cases:
In the given equation 
, there are two pairs of absolute value symbols.
Since each has two cases, there must be a total of 
different equations created.
All four cases are:
Exponents differ, hence clearly there are four possible solutions to this equation.
You can solve for all four values of 
by taking the log of both sides and using a bit of algebra to verify you have four solutions.
The answer would be 60 miles per hour
305 × 4 = 1220
215 × 2 = 430
1220 - 430 = 790
The change in the altitude of the balloon is 790 feet.
