Which ordered pairs in the form (x, y) are solutions to the equation
Ann [662]

Answer:

A, D

Step-by-step explanation:

Sub the x and y values into the equation. The x value is the first number in the coordinate, and the y value is the second number.

If the left side is equal to the right side, it is a solution.

Example:

4x-5y=24

4(-9)-5(-12)=24

-36+60=24

24=24

Remember: if the left side does not equal the right side, it is not a solution.

I need help please on all

1. B. The retail price would be the purchase price plus the markup.
So p+.40p = 1.40 p = 1.4 p. (p is really 1 p)
C. You would multiply: 1.4(56) = $78,40
D. You could multiply .4p = .4(56). OR subtract: 78.40-56 = $22.40

2. Done
3. 10(.35) = $3.50 —— 10+3.50=$13.50
4. 40(.25) = $10 ———- 40+10=$50
5 Done
6. $30.50/30% markdown 30.50(.30) = $9.15; 30.50-9.15= $21.35
7. $105/75% markdown 105(.75) = 78.75; 105-78.75= $26.25
8. $325/15% markdown 325(.15) = 48.75; 325-48.75= $276.25
9. C/40%markup Total retail:.40c + c = 1.40C
