1. Ashton graphed a system of equations with infinitely many solutions. What must be true about the equations of the lines? a. They have the same slope. b. They have different y-intercepts. The lines are parallel. d. All of the above.

The answer would be (c)

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.
