Kyle and Melissa compare their walking rates. Kyle walks 4 feet per second and Melissa walks 2.5 feet per second. A)Which equation represents the distance, d in feet that Kyle walks in t seconds?
B)Which equation represents the distance, d in feet that Melissa walks in t seconds?
C)How many feet can Melissa walk in 45 seconds?
D)How long will it take Kyle to walk 80 feet?
E)Which point tells you that Kyle can walk 28 feet in 7 seconds?
PLEASE HELP QUICKLY

(a) d = 4t

(b) d = 2.5t

(c) 45 = 2.5(x) x = 18

(d) d = 4(80) d = 320

(e) If Kyle walks 4 feet per second, then after 7 seconds he will walk 28 feet. 28 = 4(7)

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
