Answer:
Step-by-step explanation:
Compare the equation with the standard form, y=ax2+bx+c . Since the value of a is positive, the parabola opens up.
So, y=0 implies, by the zero product property, x+4=0 or x−2=0 .
Substitute x=−1 in the equation y=−x2−2x+8 to find the y -coordinate of the vertex.
Answer:
20x² - 8x + 14

<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define expression</u>
4x² - 7x - 24x² - 7x - 2 - (-3x - 8 - 3x - 8)
<u>Step 2: Simplify</u>
- Combine like terms (x²): -20x² - 7x - 7x - 2 - (-3x - 8 - 3x - 8)
- Combine like terms (x): -20x² - 14x - 2 - (-6x - 8 - 8)
- Combine like terms (Z): -20x² - 14x - 2 - (-6x - 16)
- Distribute negative: -20x² - 14x - 2 + 6x + 16
- Combine like terms (x): -20x² - 8x - 2 + 16
- Combine like terms (Z): -20x² - 8x + 14
3 * 10 is 30 because 10 you would just add a zero behind the three

Answer:
I think it might be (x + 9)5 = 4 or 5(x + 9) = 4. I'm not really sure.
I hoped this helped
