Amine equipment room is 40 meters below the surface of the ground. the work area of the 5 times deeper. what is the elevation of the work area?

The elevation of the work area is 200 meters below the surface of the ground

Step-by-step explanation:

Let

x -----> the elevation of the work area

y ----> the elevation of a mine equipment room

we know that

The elevation above the surface of the ground is positive

The elevation below the surface of the ground is negative

we have

---> is negative because is below the surface of the ground

The work area of the mine is 5 times deeper than the elevation of a mine equipment room

so

substitute the value of y

therefore

The elevation of the work area is 200 meters below the surface of the ground

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.
