Answer:

The point
(0,0) is not a solution of the system of inequalities

Explanation:

we have

$y\leq x^(2) -4$ -----> inequality A

y> 2x-1 -----> inequality B

we know that

If a ordered pair is a solution of the system of inequalities

then

the ordered pair must be satisfy the inequalities of the system

Verify

For
x=0, y=0

substitute the value of x and the value of y in the inequalkity A and in the inequality B

Inequality A

$0\leq 0^(2) -4$

$0\leq -4$ -------> is not true

therefore

The point
(0,0) is not a solution of the system of inequalities
