Answer:

11/2 = y

Step-by-step explanation:

You have it all but solved. Now, multiply both sides of the equation by 5/2, the inverse of the coefficient of y.

(5/2)(11/5) = (5/2)(2/5)y

11/2 = y

Determine which ordered pairs fall on the graph of f(x) = -2x-1

Pavlova-9 [17]

Answer:

No order Pair fall on the graph

Step-by-step explanation:

The given Function is

$f(x)= -2x -1$ ...............(i)

Now to see whether these ordered pairs Lay on it we will put each ordered pair in the equation (i)

Lets take first ordered pair (1,1)

here x = 1

putting it in (i) gives

$f(1)= -2(1) -1$

$f(1)= -3$

this is not equal to 1 so the order pair (1,1) does not fall on function $f(x)= -2x -1$

Lets take second ordered pair (-1,-4)

here x = -1

putting it in (i) gives

$f(-1)= -2(-1) -1$

$f(-1)= 1$

this is not equal to -4 so the order pair (-1,4) does not fall on function $f(x)= -2x -1$

Lets take third ordered pair (-2,-1/8)

here x = -2

putting it in (i) gives

$f(-2)= -2(-2) -1$

$f(-2)= 3$

this is not equal to -1/8 so the order pair (-2,1/8) does not fall on function $f(x)= -2x -1$

Lets take fourth ordered pair (0,-1/2)

here x = 0

putting it in (i) gives

$f(0)= -2(0) -1$

$f(0)= -1$

this is not equal to -1/2 so the order pair (0,-1/2) does not fall on function $f(x)= -2x -1$

<span>Say the code only needed to be one number long. Going from 0-9, there are ten digits. Therefore, there are ten unique codes.

Now say the code has to be two numbers long. There are ten possibilities for the first digit, 0-9. But the second digit only has nine possibilities, since each number has to be different. (The first number might be 0, so the second can only go from 1-9) For each of the first ten possibilities, there are nine possibilities for the second. We multiply those two numbers together, 10 * 9, and we get 90.

Now we just extend the logic. The third number only has eight possibilities, while the fourth number only has seven. 10 * 9 * 8 * 7 = 5040 possible codes. I hope this helped! has a great day! :)</span>
