A cyclist is riding on a straight trail that is 30 miles long. She starts at mile marker 9. She stops for lunch at the midpoint of the trail. She gets a flat tire midway between
where she stopped for lunch and the end of the trail.
At what mile marker did she get the flat tire?

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

the square root of 16 is 4.

4*4 = 16

answer-

a. the total cost of a taxi ride includes an initial charge of approximately $3.30

solution-

in the graph,

x axis represents the distance traveled and

y axis represents the total fare

the best fit line intersects the y axis approximately at 3.30 or y-intercept is 3.30. at x=0, i.e when the taxi is still, the value of y or the cost of the fare is 3.30. that means $3.30 is the fixed charge which will be levied along with the other fare.

the slope of the line represent the cost per mile. as the best fit line is straight line, so the price per mile is constant.
