Divide using synthetic division. ( x^4-12x^2-9)/(x+3)
Firdavs [7]

Answer:

x^3 - 3x^2 - 3x + 9 + (-36/(x+3))

OR

x^3 - 3x^2 - 3x + 9 - (36/(x+3))

Step-by-step explanation:

First set the divisor equal to 0:

x + 3 = 0

Subtract 3 from both sides

x = -3

This is what you'll divide the dividend by in synthetic division.

Take the coefficents of each term in the dividend. Do not forget the 0 placeholders:

x^4 + 0x^3 - 12x^2 + 0x -9

Coefficents: 1. 0.  -12. 0 -9.

Please see the image for the next steps.

The remainder is -36. Put the remainder over the divisor and add it to the polynomial (shown in image)

-36/(x+3)

Given the system of inequalities: 4x – 5y < 1 one-halfy – x < 3 which shows the given inequalities in slope-intercept form
kkurt [141]

The slope- intercept is y> (1-4x) / 5 and y< 2x + 6

<h3 /><h3>What is inequality?</h3>

A  statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Given:

4x – 5y < 1  and 1/2y – x < 3

Solving

4x – 5y < 1

-5y < 1- 4x

-y < (1-4x) / 5

y> (1-4x) / 5

Now, the second inequality,

1/2y – x < 3

1/2y< 3+x

y< 2x + 6

Determine the intervals on which the function is increasing, decreasing, and constant. (3 points)
Cerrena [4.2K]

Answer:

A)  increasing x > -1 ; decreasing x <-1

Step-by-step explanation:

We use the given graph to find the intervals where the function is increasing , decreasing and constant

We analyze the graph from the left

From the left the graph starts decreasing and it is decreasing till -1

From the point (-1,0) the graph changes direction and starts increasing

So we can say that the function is decreasing from -infinity to -1

and increasing from -1 to infinity

decreasing from -infinity to -1 means decreasing x <-1

increasing from -1 to infinity means increasing x > -1
