2. A submarine submerged at a depth
of -40 ft dives 57 ft more. What is
the new depth of the submarine?
What is the answer?

The depth is -97 ft  or 97ft below the surface

Step-by-step explanation:

We start at -40 ft              -40

The we go down 57 ft    -57

We are at                     -40-57 = -97

The depth is -97 ft  or 97ft below the surface

If the submarine starts at -40ft below sea level, then we can subtract to find the depth of the submarine when it goes 57ft deeper.

-40 – 57 = -97ft deep or 97ft below sea level.

Best of Luck!

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
