What is the solution to the system of equations below?

Burka [1]

Answer:

(x, y) = (-4, -15)

Step-by-step explanation:

You can equate the expressions for y and solve for x.

3/4x -12 = -4x -31

Adding 4x+12 gives ...

(4 3/4)x = -19

(19/4)x = -19

Multiplying by 4/19, we find ...

x = -4

Substituting that into the first equation, we can find y:

y = (3/4)(-4) -12 = -15

The solution is (x, y) = (-4, -15).

What are the possible numbers of positive, negative, and complex zeros of f(x) = −x6 − x5 − x4 − 4x3 − 12x2 + 12?

ad-work [718]

$f(x) = -x^6 -x^5 - x^4 - 4x^3 - 12x^2 + 12$

There is only one change of sign, so there is only one possible positive root.

$f(-x) = -(-x)^6 -(-x)^5 - (-x)^4 - 4(-x)^3 - 12(-x)^2 + 12\\
f(-x) = -x^6 +x^5 - x^4 + 4x^3 - 12x^2 + 12$

There are five changes of signs, so there are 5,3 or 1 possible negative roots.

The number of complex roots can be equal to 4,2 or 0 (degree of a polynomial - possible positive roots - possible negative roots)

If you take 19 6-cylinder sedans and add 12 4-door sedans you get 31, therefore making 2 red and neither 6-cylinder nor 4-door sedans. Hope this helps!
