Describe the end behavior of a 9th degree polynomial with a negative leading coefficient??

Answers

Answer:

Up left, down right

Step-by-step explanation:

First, polynomials with odd degrees will have end behaviors in two different directions.

Since the leading coefficient is negative, the end behavior will be up left and down right.

So, the end behavior is up left, down right.

The end behavior of a 9th-degree polynomial with negative leading coefficients is up left, downright.

Graph the line that has a slope of 8 and includes the point (0,2).

Answers

Graph the point (0,2). From there go up 8 points and right 1 point. Again, from the point (0,2) go down 8 points and left 1 point. Hope this helps!

The graph for the given slope of 8 and includes the point (0,2) is given below.

Given that, the line that has a slope of 8 and includes the point (0,2).

What is slope of a line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Substitute m=8 and (x,y)=(0, 2) in y=mx+c, we get

2=8(0)+c

c=2

Put m=8 and c=2 in y=mx+c, we get

y=8x+2

Graph the line using the slope and y-intercept, or two points.

Slope: 8

y-intercept: (0,2)

Coordinate points are (0, 2) and (1, 10)

Hence, the graph for the given slope of 8 and includes the point (0,2) is given below.

What is the solution to the following system of equations?

x - 2y = 6

y = 11 - 3x

Answers

Answer:

(4, -1)

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Algebra I

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

x - 2y = 6

y = 11 - 3x

Step 2: Rewrite systems

Define:                              x - 2y = 6Add 2y on both sides:     x = 2y + 6

x = 2y + 6

y = 11 - 3x

Step 3: Solve for y

Substitute in x:                              y = 11 - 3(2y + 6)Distribute -3:                                 y = 11 - 6y - 18Combine like terms:                     y = -6y - 7Add 6y on both sides:                  7y = -7Divide 7 on both sides:                y = -1

Step 4: Solve for x

Define:                                        x - 2y = 6Substitute in y:                           x - 2(-1) = 6Multiply:                                      x + 2 = 6Subtract 2 on both sides:          x = 4

Answer:

x=4  y=-1

Step-by-step explanation:

x-2(11-3x)=6

7x-22=6

7x=22+6

Mr. Smith's wife works at an animal hospital. There is a equivalent fraction relationship between the number of dogs and cats in the kennels. If there are 20 cats in the kennels, how many dogs?

Answers

Answer:

There are 10 dogs in the kennels

Step-by-step explanation:

The equivalent fraction relationship between the number of dogs and cats in the kennels is 1/2.

Which means, if [tex]n_d[/tex] the number of dods and [tex]n_c[/tex] is the number of cats, then,

[tex]\frac {n_d}{n_c}=\frac{1}{2}\cdots(i)[/tex]

Given that there are 20 cats, so [tex]n_c=20.[/tex]

Now, from equation (i) we have,

[tex]\frac {n_d}{20}=\frac{1}{2}[/tex]

[tex]\Rightarrow n_d=\frac{1}{2}\times 20[/tex]

[tex]\Rightarrow n_d= 10[/tex].

Hence, there are 10 dogs in the kennels.

The 2 rectangles and triangles are similar to each other, so the corresponding sides between the same shape are proportional.

For the rectangle, 10 is 1 2/3 times greater than 6, so x is 12 times 1 2/3, which is 20. You can also think of it as 12 is 2 times 6 on the left rectangle, so x on the right rectangle is 2 times 10

For the triangle, the corresponding sides are NP and XZ, and XZ is 13 times as large as NP. The corresponding side to PO is ZY, and 7 times 13 is 91, so w is equal to 91.

For the two lines A and B to be parallel to each other, the value of x should be equal to 20.

What are corresponding angles?

In literal sense, corresponding means pair wise angles. Like the right corner angles of two triangles etc.

The definition of corresponding angles states that when two parallel lines cross with a third, the angles that occupy the same relative location at each junction are said to be corresponding angles to each other.

As per the given diagram of the parallel lines and the transverse the measure of the angle 2 and angle 5 should be equal, This is because the two angles are corresponding angles. Therefore, we can write,

∠2 = ∠5

3x - 20 = x + 20

3x - x = 20 + 20

2x = 40

x = 20

Hence, for the two lines A and B to be parallel to each other, the value of x should be equal to 20.
