A van travels from Town A to Town B. It uses 1 gallon of gas for every 24 miles traveled. A) How many gallons of gas does the va
Setler79 [48]

Answer:

A)  \frac{x}{8} gallons

B)  Distance between Town A and Town B is 48y  miles


Step-by-step explanation:

A)

We know, number of gallons = \frac{DistanceTravelled}{MilesPerGallon}

if miles per gallon (mpg) is given as 24 & total distance travelled is 3x miles, then, using formula we have:

Number of Gallons = \frac{DistanceTravelled}{MilesPerGallon}=\frac{3x}{24}=\frac{x}{8}


B)

Now, given is number of gallons = 2y & we know mpg is 24; <em>so what is the distance?</em>

We use the same formula and solve for distance (let distance between A and B be "D"):

NumberOfGallons=\frac{DistanceTravelled}{MilesPerGallon}\\2y=\frac{D}{24}\\D=2y*24\\D=48y

Find an equation of the line passing through the given points. Use function notation to write the equation. ​(3​,8​) and ​(4​,13
Olegator [25]

Answer:

f(x)=5x-7

Step-by-step explanation:

The given line passes through the points;

(x_1,y_1)=(3,8)

and

(x_2,y_2)=(4,13)

Let us find the slope using;

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{13-8}{4-3}

m=\frac{5}{1}=5

The equation is given by;

y-y_1=m(x-x_1)

We substitute the values into the formula to obtain;

y-8=5(x-3)

y=5x-15+8

y=5x-7

There the equation of the line is

f(x)=5x-7
