Tell whether each function is linear or non-linear. Function A Function B x 0 1 2 3 y 0 1 8 27 y = –x + 5

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

The slope-intercept form of the linear function  

[tex]y = mx+b[/tex]

where

m is the slopeb is the y-intercept

The graph of y = mx + b is a straight line. Thus, y = mx + b represents a linear function.

Analzing the function y = –x + 5

Given the linear function

y = –x + 5

comparing with the slope-intercept form of linear equation

The slope m = -1

The y-intercept b = 5

Also, the graph of a linear function is a straight line.

Thus,

The function  y = –x + 5 represents  a linear function.

Analzing the Table Function

x        0     1     2     3

y        0     1     8     27

In order to identify whether the given table represents the linear function or not, we need to make sure the given function has a constant change x and y.

If there is a constant change in x and y, then it would be a linear Function otherwise it would not represent a linear function.

There is a constant change in x values.

i.e.

1 - 0 = 1

2 - 1 = 1

3 - 2 = 1

But, there is NOT a constant change in y.

i.e.

1 - 0 = 0

8 - 1 = 7

27 - 8 = 19

It is clear that the table does not have a constant change in y-values.

Therefore, the table function does not represent the linear function

B and C trisect AD and M is the midpoint of AD. MC=8. How many units are in the length of AD?

Answers

Answer:

48

Step-by-step explanation:

B and C trisrct AD so

that means that

AB=BC=CD

M is the midpoint so AM =MD

M is also the midpoint of BC also so if MC equal 8 l, BM equal 8. We add 8 and 8 together to find the value of BC which equal 16. Since BC equal 16 and it trisects AD, AB equal 16 and CD equal 16. Add all together and we get 16+16+16=16×3=48
