Canada Olympic Park features sports training and entertainment facilities. The monster Zip line produces average speed of 120 kilometers per hour. A smaller line produces speeds represented by the function d=50h where d is the distance in kilometers after h hours. How much farther could you travel on the Monster Zip line in 0.25 hours The answers I can choose are

18km

16km

20km

17.5km

17.5 Km

Step-by-step explanation:

In Monstor zip line, it's 120 km /hour

so in 0.25 hours, it's 0.25 * 120 = 30 Km

in another small

d = 50*h

= 50*0.25

= 12.5 km

so you travel (30-12.5)km farther on the monster zip line = 17.5 Km

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
