What is the slope of a line perpendicular to the line whose equation is 3x+6y=-183x+6y=−18. Fully reduce your answer.

2

Step-by-step explanation:

The given equation of line is

We need to find the slope of a line which is perpendicular to the given line.

The given equation can be rewritten as

     ...(i)

If a line is defined as , then the slope of the line is  

In equation (i), a=3, b=6 and c=18. So, slope of the line is

Let be the slope of perpendicular line.

We know that product of two perpendicular line is -1.

Multiply both sides by -2.

Therefore, the slope of perpendicular line is 2.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
