If y = 5x − 4, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?

Mama L [17]

Answer:

x can be any value, x will be the input, y will be the output.

Step-by-step explanation:

If x = 3, If x = 6, If x = 9,

y = 5x - 4

y = 5 (3, 6, or 9) - 4

y = 11, y = 26, y = 41.

These are all possible sets of ordered pairs, but ANY Real number can be represented as X, and it will need to be in an order. These numbers are all positive, so in this case, you just have to draw out Quadrant 1 in a Coor. Plane.

X (Input) I Y (Output)

3 I 11

6 I 26

9 I 41

See, when x increases by 3, Y increases by 15. If you go on, it will be the same path, same pattern.

Hope This Helps! :)

If 2500 is to be divided among Ravi, Raju and Roy, so that Ravi gets two parts, Raju has

fenix001 [56]

Answer:

The money each will get are 500 to Ravi , 750 to Raju and 1250 to Ravi. And there percentages are Ravi's 20%, Raju's 30% and Roy's 50%.

Step-by-step explanation:

Given:

2500 is to be divided among Ravi, Raju and Roy, so that Ravi gets two parts, Raju has three parts and Roy five parts.

Now, to find the money each will get and the percentages of it.

Let the price of one part be $x.$

The price of two parts be $2x.$

The price of three parts be $3x.$

And the price of five parts be $5x.$

According to question:

$2x+3x+5x=2500.$

$10x=2500$

Dividing both sides by 10 we get:

$x=250.$

Ravi gets two parts = $2x=2\times 250=500.$

Raju gets three parts = $3x=3\times 250=750.$

Roy gets five parts = $5x=5\times 250=1250.$

Now, the percentage of the money they get:

Percentage of Ravi's share:

$\frac{500}{2500} \times 100\\=\frac{50000}{2500} \\=20\%.$

Percentage of Raju's share:

$\frac{750}{2500} \times 100\\\\=30\%.$

Percentage of Roy's share:

$\frac{1250}{2500} \times 100\\\\=50\%.$

Therefore, the money each will get are 500 to Ravi , 750 to Raju and 1250 to Ravi. And there percentages are Ravi's 20%, Raju's 30% and Roy's 50%.

Can someone please tell me the answer thank you

sukhopar [10]

Step-by-step explanation:

In the problem 5 is raised to an odd exponent(9). Thus, there is no way to halve it apart from doing 5^4.5, which equals 1397.54249, which is not a whole number.

Hope it helps <3
