Answer:

D) y = 2x + 4

Step-by-step explanation:

plug the slope and the x-and-y coordinates into the slope-intercept form of a line to get the y-intercept:

y = mx + b

2 = 2(-1) + b

2 = -2 + b

4 = b

y = 2x + 4

To check if x = 9 is the solution, we need to replace every x with 9 and simplify

(3+x)/4 = 3

(3+9)/4 = 3

12/4 = 3

3 = 3

We get the same thing on both sides, so the last equation is a true equation. This means that the first equation is a true equation when x = 9. Therefore, the solution x = 9 is confirmed.

Answer:

3(x-2)+6=6x-9

$3x - 6 +6 =6 x - 9 \\ 3x - 6x = - 9 \\ - 3x = - 9 \\ x = - 9 \div - 3 = 3$

Find the MAD of this set of data.

barxatty [35]

Answer:

2.8

Step-by-step explanation:

The given data set is;

6, 12, 10, 9, 8, 6, 2, 4, 8, 15

The mean of this set is;

$\bar X=\frac{\sum x}{n}$

$\bar X=\frac{6+12+10+9+8+6+2+4+8+15}{10}$

$\bar X=\frac{80}{10}=8$

The mean absolute deviation is given by

$M.A.D=\frac{\sum |x-\bar X|}{n}$

$M.A.D=\frac{|6-8|+|12-8|+|10-8|+|9-8|+|8-8|+|6-8|+|2-8|+|4-8|+|8-8|+|15-8|}{10}$

$M.A.D=\frac{2+4+2+1+0+2+6+4+0+7}{10}$

$M.A.D=\frac{28}{10}$

$M.A.D=2.8$
