Answer:

X=6. Y= - 6

Step-by-step explanation:

Put y=6-2x in b)

4x+3(6-2x)=6

4x+18-6x=6

-2x=6-18

- 2x=-12

Divide both sides by - 2

X=6

Put x=6 in y = 6-2x

Y=6-2(6)

Y=-6

Use the Rational Zeros Theorem to write a list of all possible rational zeros of the function.f(x) = 3x3 + 39x2 + 39x + 27
kramer

First, we can factor this to make it easier to solve:

3(x^3 + 13x^2 + 13x + 9)

Now, we can use the rational root theorem like so:

List factors of 9:

1, 3, 9.

List factors of 1:

1

Because of this, we know our possible rational roots are:

+/-1, +/-3, +/-9

If none of these zeros fit using the remainder theorem, then we know our roots will be irrational.

Debora [2.8K]

I don't know exactly what you want to know about this operation so I will put multiple answers.

No sé exactamente qué quiere saber sobre esta operación, así que pondré varias respuestas.

x-intercept =   Nothing  

y-intercept  =   ( 0 ,  6 )

Axis of symmetry = -\frac{5}{16}

Vertex  (-\frac{5}{16}, \frac{167}{32})

Parabola opens up and the Vertex is the minimum
