Find the solution of the system of equations.<br> 15x – 4y = -50<br> 3x – 2y = –16
rusak2 [61]

Answer:

x=-2, y=5. (-2, 5).

Step-by-step explanation:

15x-4y=-50

3x-2y=-16

---------------

15x-4y=-50

-5(3x-2y)=-5(-16)

------------------------

15x-4y=-50

-15x+10y=80

-------------------

6y=30

y=30/6

y=5

3x-2(5)=-16

3x-10=-16

3x=-16+10

3x=-6

x=-6/3

x=-2

Multiplying a trinomial by a trinomial follows the same steps as multiplying a binomial by a trinomial. Determine the degree and
kykrilka [37]

The <em><u>correct answer</u></em> is:

The degree of the polynomial is 4 and the maximum number of terms is 9.

Explanation:

Multiplying the terms of each trinomial that have the largest degree, we are multiplying x²(x²); this gives us x⁴.  This means the degree of the trinomial, the largest degree of all terms, is 4.

Without multiplying through, we know we will multiply each term of the first trinomial by each term of the second one.  This means that, if no terms are like to combine, we could have 3(3) = 9 terms.
