Is ( 0,0) a solution to this system? y&lt;=x^2-4 y&gt;2x-1?
Xelga [282]

Answer:

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

Step-by-step 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
