Which of the following polynomial functions is graphed below?

Answers

Answer: B. f(x)=(x+4)(x-2)^2(x+3)

Step-by-step explanation:

in the graph there's two negative x value and one positive x value

so the function should be in a form of f(x)= (x+a) (x-b)^2 (x+c)

the one with negative value has a square, (x-b)^{2}, because that's where the y = 0 (the point is hitting the (x,0))

A function cannot have the more than one of the same x-values (x= 2 y=4, x=2 y=5), but you can have more than one of the same y-value as long as it’s a diff x-value (x=2 y=5, x=3 y=5)

A line with a positive slope is parallel to one of the lines shown. What is its slope? Use the graph shown below.

Answers

Answer:

2/5

Step-by-step explanation:

first select the line that is positive which is the purple one

slope = change in y / change in x

two clear points are (0,2) and (5,4)

so you do y2-y1 / x2-x1

=(4-2)/(5-0)

=2/5

so the slope is 2/5

Identify the property on this equation 5(a + 3b) = 5a + 15b

Answers

Answer:

??????????????????????

Step-by-step explanation:

Answer: Distributive Property

The term "distribution" is also used in place of "distributive"

This property says

x*(y+z) = x*y + x*z

We multiply the outer term x with each inner term (y and z). Then we add the results.

In this case,

x = 5

y = a

z = 3b

So,

5(a+3b) = 5*a + 5*3b = 5a+15b

Find the area of this parallelogram.
5 cm height
7 cm width​

Answers

Answer:

35 cm^2

Step-by-step explanation:

To find the area you need to find the width and height which we have.

Now all you need to do is to use the formula Height x Width= area

so replace height with 5 cm and width with 7 cm

5 cm x 7 cm = area

5 times 7 is 35 so the area of the parallelogram is 35 cm^2 (cm times cm is cm^2)

Hope this helps!

Mr. Richard plans to take 25 students on a school trip. They plan to go to Zoo. The bus fee is $100 for the entire trip. Entrance fee is $2.50 per person. How much should each student pay? Note: Mr. Richard does not need to pay.

Answers

Answer:

$162.50

Step-by-step explanation:

+$100

25x2.50= $62.50

+$62.50

100+62.50=162.50

Answer:

Each student should pay $6.50

Step-by-step explanation:

The question is not very clear.

If Mr. Richard has to pay to enter:

Total cost = $100 + ($2.50×26) = $165

Cost per student = [tex]\frac{165}{25}[/tex] = $6.60

Each student should pay $6.60

If Mr. Richard doesn't have to pay to enter:

Total cost = $100 + ($2.50×25) = $162.5

Cost per student = [tex]\frac{162.5}{25}[/tex] = $6.50

Each student should pay $6.50

Subtract 7t from both sides;
