what is true about the number of sides in any regular polygon that has at least one line of symmetry passing through two vertices

Answer:

15x+5

Step-by-step explanation:

First you distribute the 5 to the 3x ( 5 times 3x=15x)

Next you distribute the 5 to the 1 (5 times 1=5)

Finally you put the two answers together 15x+1

you cant simplify it anymore because you cannot add 15x to 1

[tex]\huge\boxed{Hello\:there!:)}[/tex]

The Distributive Property states that

a(b+c)=ab+ac (we multiply a by b and c)

Let's use this fantastic property to solve our problem:

5(3x+1)

15x+5

That's our final answer.

Remember, we can't add variables and numbers together.

Step-by-step explanation:

Correlation coefficient is a quantitative measure used to determine the statistical relationships between two or more random variables or observed data values. Here -1.0 states the perfect negative correlation, while 1.0 states the perfect positive correlation. ...

Answer:

400 in³

Step-by-step explanation:

Height (h) = 10 in

Base Area [tex] \sf (A_B) [/tex] = 40 in²

Formula of Volume of Cylinder:

[tex] \boxed{ \bf{V = A_Bh}}[/tex]

By substituting values in the equation, we get:

[tex] \rm \longrightarrow V = 40 \times 10 \\ \\ \rm \longrightarrow V = 400 \: {in}^{3} [/tex]

Answer:

x=12

Step-by-step explanation:

(2x-4)/5=4

We move all terms to the left:

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

We multiply all the terms by the denominator

(2x-4)-4*5=0

We add all the numbers together, and all the variables

(2x-4)-20=0

We get rid of parentheses

2x-4-20=0

We add all the numbers together, and all the variables

2x-24=0

We move all terms containing x to the left, all other terms to the right

2x=24

x=24/2

x=12

Answer:

x = 12

Step-by-step explanation:

Given

[tex]\frac{2x-4}{5}[/tex] = 4 ( multiply both sides by 5 to clear the fraction )

2x - 4 = 20 ( add 4 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12

Answer:

The equation in the slope-intercept form will be:

[tex]y=-\frac{49}{39}x+0[/tex]

Step-by-step explanation:

Given the points

Finding the slope between the points using the formula

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-39,\:49\right),\:\left(x_2,\:y_2\right)=\left(0,\:0\right)[/tex]

[tex]m=\frac{0-49}{0-\left(-39\right)}[/tex]

[tex]m=-\frac{49}{39}[/tex]

We know that the point-slope of the line equation is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting [tex]m=-\frac{49}{39}[/tex] and (-39,49)  in the equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-49=\frac{-49}{39}\left(x-\left(-39\right)\right)[/tex]

Now writing the equation in slope-intercept form

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept

[tex]y-49=\frac{-49}{39}\left(x-\left(-39\right)\right)[/tex]

[tex]y-49=\frac{-49}{39}\left(x+39\right)[/tex]

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}[/tex]

[tex]y-49=-\frac{49}{39}\left(x+39\right)[/tex]

[tex]\mathrm{Add\:}49\mathrm{\:to\:both\:sides}[/tex]

[tex]y-49+49=-\frac{49}{39}\left(x+39\right)+49[/tex]

[tex]y=-\frac{49}{39}x+0[/tex]              ∵ [tex]y=mx+b[/tex]

Where

[tex]m=-\frac{49}{39}[/tex] and the y-intercept i.e. [tex]b=0[/tex]

Therefore, the equation in the slope-intercept form will be:

[tex]y=-\frac{49}{39}x+0[/tex]

Answer:

Step-by-step explanation:

x + y = 8 ⇔ y = - x + 8

If x = 6 , then y = - 6 + 8 = 2

( 6, 2 )

If x = 0 , then y = 0 + 8 = 8

(0, 8)

If x = 8 , then y = - 8 + 8 = 0

(8, 0)

Answer:

C

Step-by-step explanation:

a number is divisible by 5 if it ends in 5 or 0

since we know that, we know that A is not correct.

a number is divisible by 10 if it ends in 0

from this, we can see that C is the correct answer because it ends in a 0

answer=c

Answer:

A tourist receives 2376 ec currency in exchange for us 1200.

Step-by-step explanation:

This can be calculated as follows:

Tax rate = 1%

Amount of us currency = 1200

Total amount of ec currency = Amount of us currency * 2 = 1200 * 2 = 2400

Amount of tax = Total amount of ec currency * Tax rate = 2400 * 1% = 24

Net amount of ec currency = Total amount of ec currency - Amount of tax = 2400 - 24 = 2376

Net amount ec currency obtained above is the amount of ec currency which a tourist receives in exchange for us 1200.

Therefore, a tourist receives 2376 ec currency in exchange for us 1200.

Answer:

10 miles

Answer:

Solving [tex]6^2-(1.1+7.4)+1.5[/tex] we get [tex]\mathbf{29}[/tex]

Step-by-step explanation:

We need to solve:

[tex]6^2-(1.1+7.4)+1.5[/tex]

First solving brackets

[tex]=6^2-(8.5)+1.5\\=6^2-8.5+1.5\\[/tex]

Now solving 6^2

[tex]=36-8.5+1.5\\[/tex]

Now subtracting 8.5 from 36

[tex]=27.5+1.5[/tex]

Now adding the above values

[tex]=29[/tex]

So, solving [tex]6^2-(1.1+7.4)+1.5[/tex] we get [tex]\mathbf{29}[/tex]
