Answer- C(16,12)

C(n,r) = n! / r!* (n-r)!

So,

C(16,4) = 16!/ 4! * 12!

C(16,12) = !6!/ 12! * 4!

Is (4,1) a solution to the equation y=-x+3 ?

babymother [125]

Answer:

The given points ( 4 , 1 ) is not a solution of line y = - x + 3 .

Step-by-step explanation:

Given line equation as :

y = - x + 3

Now to get the solutions of line equation , we have to substitute the x-coordinate value and y-coordinate value in the given line equation , and if the coordinates satisfy the equation, then this must be the solution .

So , for points ( 4 , 1 )

Here x-coordinate is 4

And y-coordinate is 1

∴ For x = 4 , The line is y = - 4 + 3

I.e y = - 1

And For y = 1 , The line is 1 = - x + 3

I.e x = 3 - 1 = 2

So, We have check both the coordinates but they do not satisfy the line equation

Hence The given points ( 4 , 1 ) is not a solution of line y = - x + 3 . Answer

A roller coaster car goes above and below ground. Use the number line to show it’s changes in height. What is the height of the

mel-nik [20]

Answer:

The height of the car at the end of the ride is 4 m above the ground level

Step-by-step explanation:

Let

h ------> the height of the car

1) The car starts at 1 meter above ground level

the height of the car in this moment is equal to

h=+1 m----> is positive because is above ground level

2) The car drops 4 meters

the height of the car in this moment is equal to

h=1-4=-3 m -----> is negative because is below ground level

3) The car rises 13 meters

the height of the car in this moment is equal to

h=-3+13=10 m ----> is positive because is above ground level

4) The car drops 6 meters

the height of the car in this moment is equal to

h=10-6=4 m -----> is positive because is above ground level

therefore

The height of the car at the end of the ride is 4 m above the ground level
