Answer:

Andy went as furthest as possible with a gallon of gasoline

Step-by-step explanation:

Let

m ----> the distance in miles

g ----> the number of gallons of gas

step 1

<u><em>Kelley's Mileage</em></u>

Find the slope of the linear function of Kelley's Mileage

we have the points

(0,0) and (20,50)

slope=(50-0)/(20-0)\\slope=2.5\ miles/gallon

the linear equation is

m=2.5g

step 2

<u><em>Andy's Mileage</em></u>

Find the slope of the linear function of Andy's Mileage

we have the points

(15,78.75) and (30,157.5)

slope=(157.5-78.75)/(30-15)\\slope=5.25\ miles/gallon

the linear equation is

m=5.25g

step 3

Rick's Mileage

we have

m=4.8g

therefore

the slope is 4.8\ miles/gallon

step 4

Compare the slopes

5.25\ miles/gallon > 4.8\ miles/gallon > 2.5\ miles/gallon

therefore

Andy went as furthest as possible with a gallon of gasoline

Caculate the slope between the points <br> (9, 12) and (4, 17)
Scilla [17]
To calculate the slope you need to do (y2-y1)/(x2-x1). So you would get:
(17-12)/(4-9)
5/-5
=-1
Hope this helps.

The owner of an office building is expanding the length and width of a parking lot by the same amount. The lot currently measure
nasty-shy [4]

Present area = 120 * 80 = 9600 ft^2 so the new area will be 9600 + 4400 = 14000

So if increase in length = x we have

(x + 120)(x + 80) = 14,000

x^2 + 200x + 9600 - 14000 = 0

x^2 + 200x - 4400 = 0

x = 20 feet answer
