#10 please help me solve this

Given:

Line

To find:

Slope of the perpendicular line and slope of the parallel line.

Solution:

Equation of a given line:

Subtract 8x on both sides, we get

Divide by -6 on both sides.

Slope of this line is .

If two lines are perpendicular then their slopes are negative inverse of one another.

Slope of perpendicular line =

If two lines are parallel, then their slopes are equal.

Slope of perpendicular line =

-3/4; 4/3

Step-by-step explanation:

8x - 6y = -4

6y = 8x + 4

y = (8/6)x + (4/6)

y = (4/3)x + (2/3)

Perpendicular: m1 × m2 = -1

Slope: -3/4

Parallel lines: m1 = m2

Slope: 4/3

answer: add the !

step-by-step explanation: then we will answer

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
