Which of the sets of ordered pairs represents a
function? **easy** BRAINLIEST
A= {(2,-2). (5, -5), (-2, 2), (-5, 5)}
B = {(4, 2), (4, -2). (9, 3), (9, -3)}

O Only A
O Only B
O Both A and B
O Neither A nor B​

Answers

Answer 1
A function means that “for only x, there is one and only one y”. If you look at these sets, you can see that the statement is true for A, but not for B. In B, you can see that an x-value of 4 has two y-values (2 and -2) and a value of 9 also has two y-values. Therefore, only A is a function.
Answer 2
A is a set with ordered pairs. This is because for a function to work there can not be a multiple of an input number. So only A would work since there is no input number that is repeated. Hope this helps and if you could please consider marking me the brainliest, thank you!

The range of the set is 17 because the range is the largest number minus the smallest number in this set 93 is the largest and 76 is the smallest therefore you subtract them 93-76=17.

Prove each of the following statements about integers by proving thecontrapositive of the statement.A. If 3nis even, thennis even.B. Ifx y zis odd, then at least one ofx; yandzis odd.

Answers

Answer and Step-by-step explanation:

(A) Suppose 3n is even, this implies that the product of 3n is a multiple of two, let's say 2(3k) where k is a real number. Rearranging that, we have 3(2k), let 2k = n. Therefore, n is even.

(B) Suppose xyz is odd, then let x = 2k, y = 2p + 1 and z = 2q + 1. xyz = 2k(2p + 1)(2q + 1) and this is obviously even since it is a multiple of 2.

Usain Bolt of Jamaica set a world record in 2009 for the 200- meter dash with a time of 19.19 seconds. What was his average speed

Answers

Answer:

His average speed was of 10.42 m/s

Step-by-step explanation:

We use the following relation to solve this question:

[tex]v = \frac{d}{t}[/tex]

In which v is the velocity(in m/s), d is the distance(in meters), and t is the time, in seconds.

Usain Bolt of Jamaica set a world record in 2009 for the 200- meter dash with a time of 19.19 seconds.

This means that [tex]d = 200, t = 19.19[/tex]

So his average speed was of:

[tex]v = \frac{d}{t} = \frac{200}{19.19} = 10.42[/tex]

His average speed was of 10.42 m/s

The diagram shows a square.
(7x + 3) cm
Find the length of the side of the square.
3cm
(5x + 8) cm

Answers

Answer:

Step-by-step explanation:

The four sides of a square are equal.

7x + 3 = 5x + 8             Subtract 5x from both sides

7x - 5x + 3 = 8              Combine the left

2x + 3 = 8                     Subtract 3 from both sides

2x = 8-3                        Combine the right

2x = 5                           Divide by 2

x = 5/2

x = 2.5

That is not quite the answer

Side = 7x + 3

Side = 7*2.5 + 3

Side = 17.5 + 3

Side = 20.5

Answer:

x = 20

Step-by-step explanation:

First, we need to combine both equations as we know they are create a "straight angle", which is 180 degrees:

2x + 8 + 6x + 12 = 180

Next, we can combine like terms to simplify the equation:

8x + 20 = 180

Now, we can subtract 20 from each side:

8x = 160

Finally, we divide both sides by 8 to find the value of "x":

x = 20

Find the simple interest rate of a loan of $5,000 that is made for three years and requires $1,762.50 in interes

Answers

Answer:

11.75%

Step-by-step explanation:

The formula for Simple Interest is given as:

I = PRT

Where in the question

I = Interest = $,1762.5

P = Principal = $5,000

T = Time= 3 years

R = Simple Interest rate ??

To solve for R, the formula is given as:

R = I/PT

R = $1,762.5/5,000 × 3

R = 0.1175

Converting to percentage

= 0.1175 × 100

= 11.75%
