Solve the system y=x²-2 and x²+y=4.Illustrate graphically.

lawyer [7]

Answer:

Solution: $(-\sqrt{3},1),(\sqrt{3},1)$

Step-by-step explanation:

System of equation:

$y=x^2-2\text{ and }x^2+y=4$

Using substitution method.

$y=x^2-2$ substitute into $x^2+y=4$

$x^2+x^2-2=4$ (combine like term)

$2x^2=4+2$ (Addition property of equality)

$2x^2=6$ (division property of equality)

$x^2=3$ (Taking square root)

$x=\pm \sqrt{3}$

Substitute x into $y=x^2-2$

$y=(\sqrt{3})^2-2$

$y=1$

Solution: $(-\sqrt{3},1),(\sqrt{3},1)$

Now cross check the solution using graph.

What does this add up to -8g^2+(2g^2-4h)

bixtya [17]

Hi there!
The question here is -8g² + (2g² - 4h), and we are asked to find the sum of it. First, we can remove the parentheses by distributing the 'invisible' 1 next to the addition sign. This gives us -8g² + 2g² - 4h. Next, we can simplify the expression by finding like terms, which would be -8g² and 2g², as they both have the same variable to the same exponent. Therefore, our answer would be -6g² - 4h. Hope this helped and have a phenomenal day!
