Using the graph below, what is the best estimate of how much gas is used on a 250-mile car trip if the equation for the line of the best fit is y=0.03x+0.25

A. 7.8 gallons.

Step-by-step explanation:

We have been given the equation of line of best fit . We are asked to find the estimated amount of gas used on a 250 mile trip.

We can see that x-axis represents number of miles and y-axis represents gallons of gas used.

To find amount of gas used on a 250 mile trip, we will substitute in our given equation as:

Therefore, 7.8 gallons of gas will be used on a 250 milt trip and option A is the correct choice.

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
