Eric purchased a transit card to commute to his job at an electronics store. The
function y=-2.50x + 60 models the
amount of credit, y, on Eric's card. x
represents the number of times Eric rides
the local train.
Part A: What does the slope of the
function's graph represent? What does
the y-intercept of the function's graph
represent? Explain your reasoning.
Part B: Eric refills his transit card when he
has $30 or less on it. How many times
does Eric ride the train before he refills
his card? Explain your reasoning.

the equation is not included but the answer is (1.50, 2.00, 2.75)

step-by-step explanation:

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
