The slope of any line perpendicular to , where A(0, -3) and B(4, 9) are two points on the line, is m =
enyata [817]

Answer:

m = -1/3

Step-by-step explanation:

The slope of the line can be calculated using the slope formula.

m = \frac{y_2-y_1}{x_2-x_1} = \frac{9--3}{4-0} = \frac{12}{4} = 3

Since this is the line with points AB, the slope of any line perpendicular to it will be -1/3. All perpendicular lines cross at a 90 degree angle and as such their slopes are the negative reciprocals of each other. This means 3 becomes -1/3.

Solve for n:<br> 3⁄5 · n = 6
garik1379 [7]

Answer:

n = 10

Step-by-step explanation:

Solve for n:

(3 n)/5 = 6

Multiply both sides of (3 n)/5 = 6 by 5/3:

(5×3 n)/(3×5) = 5/3×6

5/3×3/5 = (5×3)/(3×5):

(5×3)/(3×5) n = 5/3×6

5/3×6 = (5×6)/3:

(5×3 n)/(3×5) = (5×6)/3

(5×3 n)/(3×5) = (3×5)/(3×5)×n = n:

n = (5×6)/3

6/3 = (3×2)/3 = 2:

n = 5×2

5×2 = 10:

Answer:  n = 10
