The fuel efficiency of one type of car is recorded in a scatterplot where the amount of gas used, x (in gallons), is paired with

sukhopar [10]

Answer:

The y-intercept is 0, which represents the amount of gas used when 0 miles are traveled. The slope is 28, which represents the miles that can be traveled with 1 gallon of gas

Step-by-step explanation:

Let

x----> the amount of gas used in gallons

y ---> the distance traveled in miles

we have

$y=28x$

This linear equation represent a direct variation

The y-intercept is the value of y when the value of x is equal to zero

For x=0, y=0

That means ----> The y-intercept is 0, which represents the amount of gas used when 0 miles are traveled

The slope is $m=28\ \frac{miles}{gallon}$

That means ----> The slope is 28, which represents the miles that can be traveled with 1 gallon of gas

Bob is hiking down a 12-mile country trail. He could hike at 3 mph for the first two hours and then go the rest of the way at 5

Volgvan

Answer:

The first option will take a total of 3.2 hours while the second option will take just 3 hours

This shows that the second option is faster

Step-by-step explanation:

Here, we want to compare two hiking options and see the one which is faster.

At any point in time;

Distance = speed * time

In the first option, he could hike at 3 mph for two hours.

Total distance covered would be 3 * 2 = 6 miles

Distance left = 12 miles - 6 miles = 6 miles

Time taken to hike 6 miles at 5 mph will be ; 6/5 = 1.2 hours

Total time for the first type hiking = 1.2 hours + 2 hours = 3.2 hours

For the second option;

Time = distance/speed = 12 miles/4 mph = 3 hours

We can see that the second option is faster
