a fish is swimming at a contest rate toward the ocean floor. the equation y=-7x-3 can be used to represent to this situation where y is the depth of the fish in meters below se level. x is the number of seconds the fish has been swimming. which staTement best describes the depth of the fish given this equation.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
