Indicate the formula for the following conditions.<br><br> C(n,r)
Serjik [45]
The formula for C(n,r), also known as "n choose r" or a combination,
is: 
nCr = n! / (r!(n-r)!),
where n is the total number of options and r is number you must choose

The number generated is the total number of possible combinations. 

The ! means factorial. For example, 4! = 4 x 3 x 2 x 1

Calculate the slope of a line with a run of 3 and a rise of 9.
Mrrafil [7]

Answer:

<u>Slope = 3</u>

Step-by-step explanation:

Slope is calculated as the "Rise/Run" of a straight line.  The Rise is the change in the value of y, or the amount y changes per change in x.  Run is the change in the x value.  A line with a run of 3 and a rise of 9 is calculated as:

Rise/Run = 9/3 or 3

This means that the value of y will increase by 3 for every increase of 1 in the value of 3.

Slope in "m" in the slope-intercept form of a straight line equation:  y = mx + b

The line y = 3x + 2 tells us the it has a slope of 3 and intercepts the y axis at x = 2.

Example points (y = 3x + 2)

(0,2)

(1,5)

(4,14)

Note that y changes by 12 when x changes by 4.  Rise/Run = 12/4 or 3.

13) -3x - 4y = 8<br>-4x - 3y=6​
Dvinal [7]

Answer:

x = 0, y = -2

Step-by-step explanation:

-3x - 4y = 8  (1)

-4x - 3y=6​ (2)

Multiply (1) by -4 and (2) by -3, we have:

12x + 16y = - 32  (3)

12x + 9y= -18​ (4)

Subtract (4) from (3), we have:

(12x + 16y) - (12x + 9y) = - 32  - (-18)

<=> 7y = - 14

=> y = - 2

Replace y with - 2 in (3), we have x = 0
