Is the following relation a function?

Is The Following Relation A Function?

Answers

Answer 1

Answer:

yes

Step-by-step explanation:

A function is any graph that the x values do not repeat.

You can check this by using this vertical line test

Run your finger or a pencil down a specific vertical (top to bottom) line on the graph, if you can see that it intersects into the graph more than once, then it's not a function.

Step-by-step explanation:

Let x represent the middle integer. Then the first is x-2, and the third is x+2. The given relation is ...

  10(x -2) = 59 +(x +2)

  10x -20 = x +61 . . . . eliminate parentheses

  9x = 81 . . . . . . . . . . . add 20-x

The table below would represent a proportional relationship except for one y-value. Identify which y-value prevents the table from representing a proportional relationship. Then, select the value that would make the table proportional.

X 1.5, 2, 4, 4.5, 7
Y 6, 8, 16, 16.5, 28

Alternative values 17, 18, 18.5, 19.5, 20

Answers

9514 1404 393

Answer:

  non-proportional y-value: 16.5

  corresponding proportional y-value: 18

Step-by-step explanation:

Each y-value is 4 times the corresponding x-value except for (x, y) = (4.5, 16.5).

The correct proportional values would be (4.5, 18).

This is a fraction equal to

270 Plants ÷ 45 Rows

We want a unit rate where

1 is in the denominator,

What equation describes this variation?
z = kxy
What is the constant of variation?
k =

Answers

Answer:

Maybe is 2y

Step-by-step explanation:

Step-by-step explanation:

z = kxy, where k is a real constant.

We have z = -75, x = 3, y = -5.

(-75) = k(3)(-5)

-75 = -15k

k = 5.

Graph the line that passes through the points (3,-4) and (3,-1) and determine
the equation of the line.

Answers

Answer:

The equation of a line:

x = 3

The graph of the line is attached below.

Step-by-step explanation:

Given the points

(3, -4)(3, -1)

Finding the slope between (3,-4) and (3,-1)

(x₁, y₁) = (3,-4)

(x₂, y₂) = (3, -1)

Using the slope formula

m = y₂-y₁ / x₂-x₁

    = -1-(-4)) / 3 - 3

    = -1 + 4 / 0

m  = ∞

The slope of the line is undefined, then, by definition, the line would be a vertical line.

As the line that passes through the points (3,-4) and (3,-1)

For a vertical line, the value of x  is the same for each and every value of  y.

Thus, the equation of a line:

x = 3

The graph of the line is attached below.

There are 12 runners in marathon and all runners have equal chance of winning. What is the probability that a person may win a bet on the race if he has to correctly select the top 3 runners and
the order they finish in?
a) 1/1320 b) 1/1728
c) 3/1728 d) 1/12
kindly solve it using permutation technique

Answers

Answer:

A) 1/1320

Step-by-step explanation:

We know there are 12 runners in the race. Of these 12 people, one of them will get first place. In other words, 12 people have a chance of getting first place. Now there are 11 people remaining to get second place. Since one of the twelfth came first place, there are now 11 runners remaining to get second place. Finally, there are 10 people remaining. Since two of the 12 people came first and second, there are 10 people remaining who can get third place. So if a person was to correctly select the top 3 runners, then he would have a chance of 1/1320. You get this by multiplying 10, 11,12. You get 1320. since you have to pick one combination of 1st,2nd, and 3rd, the answer is A.
