Answer:

x = -1

y = 3

Step-by-step explanation:

Add the two equations together.

You get:

4x = -4

You may notice that there is no <em>y</em>, and that is because the y's cancel out. -y + y = 0, so there's no use in putting <em>y </em>in.

x = -1.

Plugging x in, we get:

-1 - 2y = -7.

Move the -7 over to the left side.

6 = 2y

Therefore, y = 3.

We can check our answer by plugging the values in.

3(-1) + 2(3) is supposed to equal 3.

-3 + 6 = 3, and so we know our answer is correct.

Pachacha [2.7K]

Answer:

Polynomials are classified according to their number of terms. 4x3 +3y + 3x2 has three terms, -12zy has 1 term, and 15 - x2 has two terms. As already mentioned, a polynomial with 1 term is a monomial. A polynomial with two terms is a binomial, and a polynomial with three terms is a trinomial.

You can first use the fundamental trigonometric identity:

sin(x) ^2 + cos(x) ^2 = 1

=> cos(x) ^2 = 1 - sin(x) ^2

=> cos(x) ^2 = 1 - (-4/5)^2 = 1 - 16/25 = (25 - 16) / 25 = 9 /25

=> cos (x) = +/ - √ (9/25) = +/- 3/5

Now, analyze the sign.

In the fhird quadrant the cosine is negative, so the answer is cos(x) = - 3/5.

Answer: option C. - 3/5
