Answer:
a=6, b=-5
a=12, b=-5
Step-by-step explanation:
We have the equation
we will try to resolve for in terms of and
Then
Note that if the denominator is 0, then the division is undefined and therefore there would be no solution for x.
Then, the denominator is 0 if
.
Then, for the pairs
a=6, b=-5 and a=12, b=-5, there is no solution for x.
The distance between the 2 points is 10
The answers is A because the dice rolls on the same lane as A
Answer: The correct selling price is $29.97.
Step-by-step explanation:
