Answer:
- 9 r (-8 5r + 4)
Step-by-step explanation:
Midpoint formula is (y2-y1/2 , x2-x1/2)
(1--7/2 , -2-4/2)
(8/2 , -6/2)
(4, -3)
Okay so three outfits of shirt and shorts would be 3 shirts and 3 shorts.
each shirt is $10 so 3 x 10 is 30
64.50-30 is 34.5
divide that by 3 (the 3 shorts)
34.50 / 3 = 11.5
each pair of shorts costs $11.50
hope this helps! give me brain lists please :)
Answer:
61 is the rate at which the population changes every year
Step-by-step explanation:
Given
![2000 - 61k = 48](https://tex.z-dn.net/?f=2000%20-%2061k%20%3D%2048)
Required
Interpret 61
A linear equation has the form:
![y = mk + b](https://tex.z-dn.net/?f=y%20%3D%20mk%20%2B%20b)
or
![b + mk = y](https://tex.z-dn.net/?f=b%20%2B%20mk%20%3D%20y)
Where m is the rate
By comparison:
![mk = -61k](https://tex.z-dn.net/?f=mk%20%3D%20-61k)
![m = -61](https://tex.z-dn.net/?f=m%20%3D%20-61)
Hence, 61 represents the rate at which the population changes yearly.
<em>The negative sign implies that the populatiin reduces</em>
