Evaluate 19C1 PLEASE HELP

LiRa [457]

Answer:

${19}C_1=19$

Step-by-step explanation:

We need to find the value of ${19}C_1$ .

C stands for combination.

The formula of combination is as follows :

$nC_r=\dfrac{n!}{r!(n-r)!}$

Here,

n = 19 and r = 1

So,

$nC_r=\dfrac{19!}{1!(19-1)!}\\\\nC_r=\dfrac{19!}{1!\times 18!}\\\\nC_r=\dfrac{19\times 18!}{1!\times 18!}\\\\nC_r=19$

So, the value of ${19}C_1$ is 19.

The possible values of x are given by x+8=<6.<br><br>The greatest possible value of 7x is_____

kozerog [31]

Answer:

The possible values of x is given by $x\leq -2$ and they include: -2, -3, -4, -5, -6 and so on

The greatest possible value of 7x is $-14$

Step-by-step explanation:

We are given the equation: x + 8 <= 6

Let collect the like terms:

$x + 8 \leq 6\\x\leq 6 -8\\x \leq -2$

Therefore, x <= -2 and the possible values include: -2, -3, -4, -5, -6 and so on

To find the greatest possible value of 7x is when x = -2.

$7x = 7 * -2\\7x = -14\\$ .

The equation 3x + 6 = 12 involves two operations performed on x: multiplication by 3 followed by addition of 6. What operations

BlackZzzverrR [31]

3x + 6 = 12
First operation was subtraction (subtracting 6 to leave 3x alone)
Second operation was division (Dividing 3 from 3x to isolare x)

3x + 6 = 12
3x + 6 -(6) = 12 - 6
3x = 6

$\frac{3x}{3}$ = $\frac{6}{3}$
3 and 3 cancels out
x = 2

Chana and Josiah started skating at the same time in the same direction, but Josiah had a head start 10 meters past the starting

Deffense [45]

Point F is on line a, so it does represent Josiah's distance at a certain time. Also, point F is below line b, so it represents a distance that is less than Chana's distance. This is a distance-time graph problem.

<h3>What is the proof for the above?</h3>

Recall that Josiah had a head start of 10 meters and he skates at 2 meters per second.

Since Y is the function that represents the distance in meters from the finished line, by observation, it is clear to see that all the factors that are related to his race are adequately represented in:

y = 10 + 2x

Where 10 is the head start in meters

2 is the rate at which he skates per second; and

x is the unknown amount of time in seconds.

Given that the point F sits over 25 seconds,

that is F(y) = 10 + 2 * 25

= 60 meters.

Hence, Point F is on line a, so it does represent Josiah's distance at exactly 25 seconds.
