Answer:


Step-by-step explanation:
The given system is:
4x-3y=8
5x-2y=-11
We make x the subject in the top equation to get:

Plug this expression for x in the bottom equation to get

We expand to obtain

Multiply through by 4

This means


Given:
The polynomial is:

To find:
The degrees and determine whether it is a monomial, binomial, or trinomial.
Solution:
We have,

The highest power of the variable <em>x</em> in the given polynomial is 4. So, the degree of the polynomial is 4.
Monomial: Polynomial with one term.
Binomial: Polynomial with two terms.
Trinomial: Polynomial with three terms.
In the given polynomial, we have three terms
. So, the given polynomial is trinomial.
Therefore, the degree of the polynomial is 4 and it is a trinomial.
-7x^2 - 6x^2 + 3x + 5x - 5 + 2
-13x^2 + 8x - 3
Answer:
91.125 or 729/8
Step-by-step explanation:
take 4.5^3 to get 91.125
To find the mean you add all the #'s and divide by how many there are. 4+5+6+7 +8= 30 /5 is 6. Tara is right.
