What is the slope of a line that is perpendicular to the line shown? (0,2) (3,0)
Greeley [361]

Step-by-step explanation:

This means that if a line is perpendicular to a line that has slope m, then the slope of the line is -1 / m. For example, we found that the slope of the line y = (1/2)x + 3 is 1/2. Thus any line that is perpendicular to this line would have slope -2 /1 = -2.

Ten times the sum of half a number and 6 is 8
Genrish500 [490]

" · " - times

" + " - sum

n - a number

0.5n - half a number

10 · (0.5n + 6) = 8     |use distributive property

(10)(0.5n) + (10)(6) = 8

5n + 60 = 8     |substract 60 from both sides

5n = -52    |divide both sides by 5

n = -10.4
