Answer:

-6x -18 + 2y

Step-by-step explanation:

1. Collect like terms:

-3x + -3x = -6x

-24 + 6 = -18

2. Rewrite expression:

-6x -18 +2y

Hope this helps, good luck! :D

Answer:

64°

Step-by-step explanation:

<em>So supplement angles are equal to 180, so first our two angles added together will be 180:</em>

x + x = 180

<em>Now one of these angles is 6 greater than half:</em>

x + (x/2 + 6) = 180

<em>Then we will solve for x:</em>

x + (x/2 + 6) = 180

x + x/2 + 6 = 180

x + x/2 = 174

\frac{3}{2}x = 174

x = 116

<em>Plug it back in:</em>

x + (x/2 + 6) = 180

         /\

     x/2 + 6

   (116)/2 + 6

        64

<em>To check:</em>

116 + 64 = 180 ✓

Find the solutions to x2 = 24.<br> O A. x = +216<br> O B. x = 16.6<br> O C. x= 46<br> O D. x = +62
babymother [125]

Answer:

x =±2 sqrt(6)

Step-by-step explanation:

x^2 = 24

Take the square root of each side

sqrt(x^2) = sqrt(24)

x = ±sqrt(4*6)

x =±sqrt(4) sqrt(6)

x =±2 sqrt(6)

Enter the number of complex zeros for the polynomial function in the box.
Finger [1]

Given polynomial function:

f(x)=x^3-96x^2+400.

We need to apply Descartes' rule of sign to identify the number of complex roots.

The given polynomial is f(x)=x^3-96x^2+400

Let us see the number of sign changes in f(x)

There are 2 sign changes in f(x). One from plus to minus and second from plus to minus. Hence, there 2 or 0 positive roots.

Now, let us see the number of sign changes in f(-x)

f(-x)=-x^3-96x^2+400

There are only one sign change. Hence, there will be 1 negative roots.

The degree of the polynomial is 3.

Hence, there will be exactly 3 zeros.

<em>Therefore, the possible numbers of zeros are:</em>

<em>2 positive, 1 negative and 0 complex</em>

<em>0 positive, 1 negative and 2 complex.</em>

Let us see the graph:

In the graph, we can see that the graph cuts the x axis at three points (2 positive, 1 negative points).

<h3>Hence, the number of complex zeros for the given polynomial is zero.</h3>
