The midpoint formula is x1+x2 over 2 and y1+y2 over 2. When you use it to find the midpoint of (0,-8) and (-4,10), you get (-2,1).

Slope formula is y2-y1 over x2-x1, which will give you -6.

Vinil7 [7]

Answer:

The number sold at $12.50 is  25

The number sold at $9.50 is 62

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations:

x 12.50 + y 9.50=901.50

x+y= 87

Where

x= number of pottery pieces sold

y= number of pottery pieces sold at a decreased price  

Multiplying the second equation by 9.50, and subtracting the second equation to the first equation:

12.50 x + 9.50y = 901.50

-

9.50 x+ 9.50 y= 826.5

__________________

3 x = 75

Solving for x

x =75/3

x = 25

Replacing x=25 on any equation:

x+y= 87

25+y =87

y=87-25

y= 62

23, 24, 25, 26, and 27
Debora [2.8K]
23. Option A: 4p + 175 = 375

24. $50 per monthly payment if the down payment is $175

25. Option C: 28x + 64 = 456

26. $14 for a haircut

27. 
a. See the diagram attached. It was drawn on Google Drawing so obviously not to scale but you get the gist. 

b. 

Not quite sure what a verbal model is but with the diagram you should be able to describe it.

 4 bookshelves, 2 on each side, in an entertainment center and a middle section of 30 inches wide all add up in its entirety to equal 90 inches.

c. 

4x + 30 = 90

d. 

4x = 60
x = 15

The bookcases are each 15 inches wide
