Which graph represents the system of inequalities?

I think it's C.
sorry if i'm wrong

An easy way is to test points
try (0,0), if it's true then the answer is C
it's false, not C

try (-4,5), if it's true, it's D
it's false, it's not D

try (1,4), if it's true, it's A
it's true

answer is A

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.
