Answer:

4

Step-by-step explanation:

p=120 -5Q

when p = 80

80 = 120 -5Q

Q=8

and when p= 60

60 = 120 -5Q

Q=12

so, change in consumer surplus = 12-8

= 4

Find the slope of the line that passes through (10, 8) and (1, 1).
Nana76 [90]

Answer:

2/3

Step-by-step explanation:

the formula to find slope is y1-y2/x1-x2.

The ordered pairs are (10,8) and (1,1)

                                     (x, y).        (x, y)

So it would be: 8-1 OVER 10-1

=6/9 which simplifies to 2/3

so your slope would be 2/3

A rectangle's width is twice as long as its length. If the perimeter is 36 in., what is the length?
Bumek [7]
Okay here: 

Let L be the length and W the width of the rectangle. 

1. w=2•L
2. 2L+2W=36

Substitute eq. 1 into eq. 2, 

2L+2•(2•L)=36

2L+4L=36

6L=36

L=9

Not done yet, then from eq. 1, 
 
W=2•L
W=2•9
W=18 <------- Your answer. :)
