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.

<u>X (Input)  I  Y (Output)</u>

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! :)

scZoUnD [109]

Answer:

10 buildings

Step-by-step explanation:

<em>Incomplete question: Missing Attachment</em>

<em>I will answer your question with the attached histogram</em>

<em></em>

Required

Determine the number of tall buildings that had more than 60 floors

The histogram can be interpreted as follows:

\begin{array}{cccccc}{Floors} & {1-20} & {21-40} & {41-60} & {61-80} \ \\ {Buildings} & {10} & {5} & {15} & {10} \ \end{array}

More than 60 floors is represented with the following group: 61 - 80

The frequency of group 61 - 80 is 10

<em>Hence, 10 buildings had more than 60 floors</em>
