Answer:

The perimeter of a shape is the length around it.

Step-by-step explanation:

We will be using the x and y values and add them together to find the total perimeter.

To do this, let's find all the values of the 2 axis:

(2 to 4) = 2

(1 to 3) = 2

(4 to 10) = 6

(3 to 1) = 2

(10 to 12) = 2

(1 to 8) = 7

(12 to 2) = 10

(8 to 1) = 7

We now add these values together which gives us <em><u>38</u></em>. Don't forget to add the units afterwards (cm, m and so forth).

Answer:

$Total\ Selection = 30\ ways$

Step-by-step explanation:

Given

Girls = 3

Boys = 5

Required

How many ways can 2 boys and girls be chosen?

The keyword in the question is chosen;

This implies combination and will be calculated as thus;

$Selection =\ ^nC_r = \frac{n!}{(n-r)!r!}$

For Boys;

n = 5 and r = 2

$Selection =\ ^5C_2$

$Selection = \frac{5!}{(5-2)!2!}$

$Selection = \frac{5!}{3!2!}$

$Selection = \frac{5 * 4 * 3!}{3!*2 * 1}$

$Selection = \frac{20}{2}$

$Selection = 10$

For Girls;

n = 3 and r = 2

$Selection =\ ^3C_2$

$Selection = \frac{3!}{(3-2)!2!}$

$Selection = \frac{3!}{1!2!}$

$Selection = \frac{3 * 2!}{1 *2!}$

$Selection = \frac{3}{1}$

$Selection = 3$

Total Selection is calculated as thus;

$Total\ Selection = Boys\ Selection * Girls\ Selection$

$Total\ Selection = 10 * 3$

$Total\ Selection = 30\ ways$

Write an equation of the line in slope intercept form

tankabanditka [31]

Answer:

Step-by-step explanation:

(0, 9) (3, 0)

(0 - 9)/(3 - 0) = -9/3 = -3

y - 9 = -3(x - 0)

y - 9 = -3x + 0

y = -3x + 9

Multiple representations: bargain DVD's cost $5 each at mega movie graph the proportional relationship that gives the cost y in

krok68 [10]

Answer:

Step-by-step explanation:

With this being a proportional relationship, the y-intercept MUST be 0.

Thus, the relationship has the form y = C(x) = ($5/movie)x, where x is the number of movies purchased.

To graph this, first plot a dark dot at (0, 0). Then, starting at (0, 0), move your pencil point 1 unit to the right and from this new position 5 units up. Plot a dark dot at (1, 5). Now draw a straight line through (0, 0) to the right through (1, 5).

Answer:

Step-by-step explanation:

When you rearrange the equation, it would be y = 2x+1

If the y intercept is 1, and the slope is 2, then well c would uh work.
