Kisachek [45]

If there are 40 children aged twelve and under and x of them are under three years old, 40 - x aged three twelve years old. From the 92 people that where taken by the company on whale watching trips, 52 are over twelve years old. The equation that best show the total cost, C is
(40 - x)(36) + (52)(48) = C
Rearranging the equation gives,

If a line has a slope of 3, what is the slope of a perpendicular line?

pashok25 [27]

Answer:

Slope of perpendicular line is -1/3

Step-by-step explanation:

The slope of the given line is 3 and we have to find the slope of the perpendicular line.

We know that the slope of two perpendicular lines are negative reciprocal of each other.

In other words if the slope of the line is m then then slope of the perpendicular line is $-\frac{1}{m}$
