Answer:
5.91 in
Step-by-step explanation:
1 cm = 0.393701 in
15 cm * 0.393701 in = 5.90551 in
Round to hundredth: 5.91 in
The equation of the line in point-slope form is y = -1/3 x + 20/3 and 3y + x = 20
<h3>Equation of a line</h3>
The equation of line perpendicular to another line in point slope form is expressed as;
y-y₁ = -1/m(x-x₁)
Given the equation of a line x -3y - 8 = 0
x - 3y = 8
-3y = -x + 8
y = 1/3x - 8/3
Slope m = 1/3
Substitute the point (-7, 9) and slope 1/3 into the equation
y-9 = -1/3(x-(-7))
y-9 = -1/3(x+7)
3(y-9) = -(x+7)
3y-27 = -x -7
3y = -x + 20
y = -1/3 x + 20/3
Write in general form.
3y = -x + 20
3y + x = 20
Hence the equation of the line in point-slope form is y = -1/3 x + 20/3 and 3y + x = 20

8, to find the mean you need to add all the data points in this case 9,5, and 10 then divide with the number of data points in this which case there are 3 data points. So to find the answer you would add 9+5+10 and you’d get 24 you’d then divide 24 with 3 and get the answer which is 8
