Answer: The correct answer is the third option, (-3,-4).
Step-by-step explanation: You plug in 2x + 2 for y, given that y = 2x + 2.
2x+2 = x - 1
x = -3
Now, you plug in -3 for x in an equation.
y = -3 - 1
y = -4.
(-3, -4)
Ugh can I see the fulll question
Setup Fee= $5,500Per CD Charge= $1.00Desired Cost Per CD= $3.50
x= number of CDs
Desired Cost Per CD= Cost per CD + Setup Fee
($3.50 * x)= ($1.00 * x) + $5,500multiply inside parentheses
$3.50x= $1.00x + $5,500subtract $1.00x from both sides
$2.50x= $5,500divide both sides by $2.50
x= 2,200 CDs
ANSWER: x= 2,200 CDs
Hope this helps! :)

No, 50 is not a perfect square. A perfect square is any number that can be divided by any number to get the quotient as the same number AND the quotient must be rational. When you divide 50 so that the quotient equals the divisor, you will get an irrational number. Therefore, 50 is not a perfect square.
