Answer:
Step-by-step explanation:
To use substitution in this problem, you find the Y which ='s -3. That we have clear. Now, the second equation becomes x - 5(-3) =7. A negative times a negative is a positive, so 15. Now, we have x + 15 = 7. Subtract 15 from 7 to get x = -8. Your coordinates, or your answer, will be (-8, -3)
Using the definition of polynomial, it is found that options D and E are polynomials.
D.
E.
-----------------------
A polynomial of the nth degree is defined by the following equation:
The exponents n are integers, and have to be non-negative.
- In options A and C, there are negative exponents(, and thus, they are not polynomials.
- In option B, , that is, a fractional exponent, thus also not a polynomial.
- In options D and E, the exponents are integers and non-negative, thus they are polynomials.

Answer:
Two functions are equal if they have the same domain and codomain and their values are the same for all elements of the domain.
It would take 15 minutes.
21/7=3
5/3=1.666666666667
1.6666666667*3=approx. 5
5*3=15
Hope it hepls :)
