The shore of the Dead Sea, which is the lowest dry land on Earth, has an elevation of -413 meters. Death Valley which is the lowest dry land in the United States of America has an
elevation of -86 meters. How much greater is the elevation of Death Valley than the
elevation of the Dead Sea Shore?

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

step-by-step explanation:

fdddff

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
