A.The elevation of city D=
feet
B.The elevation of city D=-8 feet
because it is 8 feet below the sea level therefore, it takes negative.
Step-by-step explanation:
We are given that
The elevation of city A=-80 feet
The elevation of city C=-16
The elevation of city D=1 over 2 of the city C
A.We have to find an expression to represent the elevation in feet of city D.
The elevation of city D=
feet
B.We have to solve the expression and explain .
The elevation of city D=
The answer is negative because the elevation is below the sea level.
The sea level is like as origin and the elevation measured on the negative y- axis below the origin means sea level.
So, the elevation of city D is 8 feet below the sea level and taken -8.
