Suppose a van gets 22 mi/gal. The distance traveled D(g) is a function of the gallons of gas used
babymother [125]

Answer:

a) Table and graph showed

b) The distance will be 231 miles

c) Yes

Step-by-step explanation:

We know the van gets 22 mi/gal, so the distance D in miles traveled by the van can be expressed as  

D(g)=22g, being g the number of gallons of gas used

a) The graph of the function D and its corresponding table of values is shown below.  

b) If the van used g=10.5 gallons of gas, the distance would be:

D(10.5)=22 x 10.5 = 231 miles

c) The values of g are real in nature because they represent the amount of gas consumed by the van and it can be any real positive number. Being D a linear function of g, it also happens to take positive real values. Then it makes sense to connect the points with lines.

25 Points for answer
Luden [163]

Answer: 2

Step-by-step explanation:

First you have to plug in the value for x which is -18 so then you're equation then get y by itself and solve for y. This becomes

-3(-18) -y = 56

54 - y = 56

-54 -54

Y=2

You can check your work by plugging in 18 for x and 2 for y and when you solve the equation your answer should equal 56.
