Evaluate 3•r•(t—v) if r=2, t=6, and v=4

Step-by-step explanation:

Put the values r = 2, t = 6 and v = 4 to the expression 3•r•(t—v):

3 • 2 • (6 - 4)

First parenthesis 6 - 4 = 2

3 • 2 • 2 = 6 • 2 = 12

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
