A and d seem correct to me.
b and c are definitely wrong.
Standard Form: ax² + bx + c = y
Basically, you put all the numbers from greatest to least with exponents then variables.
We have the numbers:
9
-x²
2x^5
-7x
Put these numbers from least to greatest from the exponents.
2x^5 - x² - 7x + 9
The degree of the polynomial is the number with the greatest exponent. In this case, the highest exponent is 5.
The degree of the polynomial is 5.
Best of Luck!

Answer: see below
<u>Step-by-step explanation:</u>
1) Foci is plural for Focus. Since a hyperbola has two focus points, they are referred to as foci. The foci is where the sum of the distances from any point on the curve to the foci is constant.
2) When determining the equation of a hyperbola you need the following:
a) does the hyperbola open up or to the right?
b) what is the center (h, k) of the hyperbola?
c) What is the slope of the asymptotes of the hyperbola?
3) The equation of a hyperbola is:

- (h, k) is the center of the hyperbola
- ± b/a is the slope of the line of the asymptotes
- The equation starts with the "x" if it opens to the right and "y" if it opens up
21/50
21/50 is in its most simple form because it cannot be broken down any further.
Answer: 21/50
