Find the value of x.

Answer:

[tex]140[/tex]

Step-by-step explanation:

A regular polygon is a shape with equal sides and angles. Because of this, we can write the following equation to set two sides equal to each other:

[tex]3a+b+3=2a+2b+6[/tex]

Solving, we will get a in terms of b:

[tex]3a=2a+b+3,\\a=b+3[/tex]

Now we can substitute a for (b+3) into our equation:

[tex]5a-2b+1=2a+2b+6,\\5(b+3)-2b+1=2(b+3)+2b+6,\\3b+16=4b+12,\\-b=-4,\\b=\boxed{4}[/tex]

Therefore, the length of each side of this polygon is [tex]5(4+3)-2(4)+1=28[/tex].

Since the perimeter of the polygon consists of all five sides, the perimeter is:

[tex]p=28\cdot 5 =\boxed{140}[/tex]

Answer:

14.25

Step-by-step explanation:

So, lets go over our information.

We have a price of 15 dollars.

And it is 5% cheaper.

This means that the price is 95% of what it used to be.

We must find 95% of 15.

We know that to put 95% into decimal form, we must divide by 100:

95/100

=

0.95

So we know we must multiply 15 by 0.95:

15x0.95

=

14.25

So our price is now 14.25 dollars

hope this helps! :)

Answer:

A

Step-by-step explanation:

It is A. The problem asks for the interval when the marlin's height is always increasing. Therefore, you want to look at the left half of the parabola, as the line is going into the peak. The right half is declining. The peak is at around 2 (on the x-axis), so you know that the ending interval number has to be 2. The marlin's height begins to go up starting at 0, so the interval is 0 <= x <= 2. Any number past two is a declining height, and the increase starts at 0.

Answer:

Ratio of goat to total number of animals at the zoo = 2 : 5

Step-by-step explanation:

Chickens = 2

Deer = 4

Donkeys = 3

Goats = 6

Total animals at the zoo = 15

what is the ratio of goats to the total number of animals at the zoo?

Ratio of goat to total number of animals at the zoo = 6 : 15

= 6/15

= 2/5

Ratio of goat to total number of animals at the zoo = 2 : 5

Answer:

Divide them by the same number

Answer:

2,1,4,3,6,5,8,7

Step-by-step explanation:

Given:

2,1,4,3,6,5,8,___

Pairing the sequence in twos

2,1

4,3

6,5

It can be seen that each pair of the sequence is arranged in descending order (from highest to lowest)

1, 2 is written as 2,1

3, 4 is written as 4,3

5, 6 is written as 6, 5

Then the next two numbers

7, 8 will be written as 8,7

2,1,4,3,6,5,8,7

The answer is 28.2 because 479.4 ft. ÷ 17 ft. = 28.2 ft.

Answer:

(x + 2) (8x + 3)

Step-by-step explanation:

[tex]8x^{2}[/tex] + [tex]19x + 6[/tex]

= (x + 2) (8x + 3)

L = 3/a = 3/8

R = 16/a = 16/8 = 2

\ac/

L V R

/ \

/ b \

where letters have their usual meaning. Comparing 8x² + 19x + 6 to ax² + bx + c,

ac = 8*6 = 48

b = 19

Factors of ac or 48 :-

1 * 48

2 * 24

3 * 16

As the sum of 3 and 16 is 19(or b), our required pair is 3 and 16.

On the left side:

L = 3/a = 3/8

On the right side:

R = 16/a = 16/8 = 2

Therefore, factorized form is (x + 3/8)(x + 2) which can be written as (8x + 3)(x + 2).

How this method works:

Make a X with ac and b on the top and bottom of the X, where ac and b are taken from ax² + bx + c.

On the left side we have d/a and e/a. Basically d and e are those values that we get after solving the whole question.

Step1: find the pair(s) for which sum of factors of ac = b. Here it is 3 and 16.

Step2: put these values in place of d and e.

Step3: solve left anf right of X,

Left = d/a = 3/8

Right = e/a = 16/8 = 2

Step4: whatever you get, put that in (x+?)(x+?) in place of ?.

Answer:

x > -2

Step-by-step explanation:

-3x + 2 < 8

our goal is to isolate the x

subtract two from both sides

-3x < 8 - 2

- 3x < 6

divide both sides by -3

flip the sign because we divided by a negative number

x > -2

Answer:

x=7 is the line parallel to the given line x=8 . Parallel lines are the lines which are always same distance apart and never intersect. The given line is x=8 with intersects the x axis at x=8 and it is parallel to y axis with slope infinite or not defined.

Answer:

8.5 = $35,000

2% = $18,000

Step-by-step explanation:

two equations can be derived from the question

x + y = $53,000 equation 1

0.02x + 0.085y = $3,335.00. equation 2

x = amount invested in 2% bond

y =  amount invested in 8.5% bond

multiply equation 1 by 0.02

0.02x + 0.02y = 1060 equation 3

subtract equation 2 from 3

0.065y = 2275

y = 35,000

substitute for y in equation 1

53,000 - 35,000 = 18,000

Answer:

-4, -2, 6, 10, 12

Step-by-step explanation:

The function is h(x) = 2x + 4. H(x) is basically just another way of writing "y", so we technically have y = 2x + 4. We can complete the table by substituting the value of x that the table gives us.

The table gives us x = -4 and wants us to find h(x), or y. So, we do y = 2(-4) + 4 and we get y = -4.

The table gives us x = -3 so we do y = 2(-3) + 4 and we get y = -2.

The table gives us x = 1 so we do y = 2(1) + 4 and we get y = 6.

The table gives us x = 3 so we do y = 2(3) + 4 and we get y = 10.

The table gives us x = 4 so we do y = 2(4) + 4 and we get y = 12.

Answer:

The answer is A) There are no proportional relationship

Step-by-step explanation:

The green line does not go through the origin and it is curved. This is not a proportional relationship.

Problems: It does not go through 0,0 and it is curved.

----------------------------------------------------------------------------------------------------------------

The blue line may go through the origin but it is curved. This is not a proportional relationship.

Problem: It is curved.

----------------------------------------------------------------------------------------------------------------

The purple line does not go through the origin. This is not a proportional relationship.

Problem: It does not go through 0,0

----------------------------------------------------------------------------------------------------------------

Conclusion: Since the green, blue, and purple line are not proportional, this means zero lines are proportional.

Note:

I know my answer is very late but I wanted to help anyone who needs it for future reference.

The graph has 0 proportional relationships.

What shows proportional relation?

The graph of a proportional relationship is a straight line through the origin or a ray whose endpoint is the origin.

In the given graph, only one purple color curve is a straight line but it is not starting through the origin.

Therefore, the graph does not have any proportional relationships.
