Is ( 0,0) a solution to this system? y<=x^2-4 y>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

Y=-3x^2+6x+c; (1,0) find C

kogti [31]

<span>Simplifying 3x2 + -6x + c = 0 Reorder the terms: c + -6x + 3x2 = 0 Solving c + -6x + 3x2 = 0 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '6x' to each side of the equation. c + -6x + 6x + 3x2 = 0 + 6x Combine like terms: -6x + 6x = 0 c + 0 + 3x2 = 0 + 6x c + 3x2 = 0 + 6x Remove the zero: c + 3x2 = 6x Add '-3x2' to each side of the equation. c + 3x2 + -3x2 = 6x + -3x2 Combine like terms: 3x2 + -3x2 = 0 c + 0 = 6x + -3x2 c = 6x + -3x2 Simplifying c = 6x + -3x<span>2</span></span>
