A high -speed elevat6 can rise 480 feet in 30 seconds. which expression represent the rate, in fret per minute, of elevator?

1 answer:

5 0

If an elevator rises 480 feet per 30 seconds, then it would rise 960 feet per minute.

You get this answer by doubling 480 because there are 60 seconds in a minute, and you have to also double 30 seconds to get 60 seconds. 960ft/1min is the answer.

Answer:

Step-by-step explanation:

Equation for the linear function has been given as,

y = 26 - 4x

For x = 1,

y = 26 - 4(1)

= 26 - 4

= 22

For x = 2,

y = 26 - 4(2)

= 26 - 8

= 18

For x = 3,

y = 26 - 4(3)

= 26 - 12

= 14

For x = 6,

y = 26 - 4(6)

= 26 - 24

= 2

Therefore, table for the function will be,

x y

1 22

2 18

3 14

6 2

Answer:

<u>The slope is -3.</u>

Step-by-step explanation:

The slope is the Rise/Run between the two points. The change in y for every change in x. Take the two points and calculate the:

RISE = (-6 - 3) = -9

RUN = (8 - 5) = 3

Rise/Run, or slope, is = -9/3 or -3

I graphed a line with slope of -3 and then added 18 to force the line to intersect the two given points.
