a gold mine has two elevators, one for equipment the other for miners. The equipment elevator descends 4 feet per seconds. The elevator for the miners descends 16 feet per seconds. One day, the equipment elevator begins to descend. After 17 seconds, the elevator for the miners begins to descend. What is the position of each relative to the surface after another 18 seconds? at time, witch elevator is deeper? the position of the equipment relative to the surface to the surface feet is? please help :D

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.
