What is the slope y+2=1/4(x-3)

ioda

Answer:

$m=\frac{1}{4}$

Step-by-step explanation:

Given

$y+2=\frac{1}{4}(x-3)$

Required

Find the slope

$y+2=\frac{1}{4}(x-3)$

Subtract 2 from both sides

$y+2-2=\frac{1}{4}(x-3) - 2$

$y=\frac{1}{4}(x-3) - 2$

Open bracket

$y=\frac{1}{4}x-\frac{1}{4}*3 - 2$

$y=\frac{1}{4}x-\frac{3}{4} - 2$

Take LCM

$y=\frac{1}{4}x+\frac{-3 - 8}{4}$

$y=\frac{1}{4}x+\frac{-11}{4}$

$y=\frac{1}{4}x-\frac{11}{4}$

An equation has the form:

$y = mx + b$

Where

$m = slope$

By comparing: $y = mx + b$ and $y=\frac{1}{4}x-\frac{11}{4}$

$m=\frac{1}{4}$

<em>So, the slope is 1/4</em>

Find the mean absolute deviation of the set of data 3,8,10,12,15

inn [45]

Answer:

3.28

Step-by-step explanation:

find the mean of all the numbers

3 + 8 + 10 + 12 + 15 = 48

48/5=9.6

so the mean of all the numbers is 9.6

now subtract 9.6 from all the numbers

|3 - 9.6| = 6.6

|8 - 9.6| = 1.6

|10 - 9.6| = .4

|12 - 9.6| = 2.4

|15 - 9.6| = 5.4

Find the mean/average of the new values

6.6 + 1.6 + .4 + 2.4 + 5.4 = 16.4

16.4/5 = 3.28

22 points. The windows on the top row of a building are similar to the windows on the bottom row. Rectangle ABCD is similar to r

juin [17]

PQ are the first two letters and AB are the first two letters.

Since the windows are similar the letters in one are in the same orientation as the other ones.

This means PQ would be the same as AB

PQ = 60

The answer is A. 60 in.
