Answer:
1. {5,-9}
2.{4}
3.{9/2}
Step-by-step explanation:
The equation 
can be solved as follows:
Then, the solutions of the equation are 
.
Now, if 
, we can solve the equation 
as follows:
So, the unique solution of this last equation is 
The last equation is 
, where 
. To solve this equation we can proceed as follows:
But, x=11/4 is not a solution of this equation. So the unique solution is x=9/2.
Answer:
Step-by-step explanation:
To find the quotient, convert the mixed number to an improper fraction first
Find the quotient now
Simplify
Divide by 
both numerator and denominator
Convert to a mixed number
Answer: 84 = 8p - 1 (or $84 = $8p - $1, but it is usually put together like the first equation)
Step-by-step explanation: $84 is the break even point, so the equation must be able to come out to at least $84 if it is correct.
$84 in equation is break even
8p/$8p is the price per painting
-1/-$1 is the addition from the canvas
Point slope form, y-y1 = m(x-x1)
Here, y1 = -1, x1 = 4, m=8
so, it would be: (y+1) = 8(x-4)
