what is the slope of a line perpendicular to the line whose equation is 5x+6y=42. fully reduce your answer​
oksian1 [2.3K]

Answer:

the slope of the line that is perpendicular to the given line is  \frac{6}{5}

Step-by-step explanation:

As the slope intercept form is

y=mx+b

Where

  • m is the slope
  • b is the y-intercept

Considering the equation

5x+6y=42

\mathrm{Slope-Intercept\:form\:of}\:5x+6y=42:\quad y=-\frac{5}{6}x+7

\mathrm{Slope\:of\:}-\frac{5}{6}x+7:\quad m=-\frac{5}{6}

As we know that perpendicular lines have negative reciprocal slopes.

So,

-\frac{1}{-\frac{5}{6}}=\frac{6}{5}

Hence, the slope of the line that is perpendicular to the given line is \frac{6}{5}

Keywords: slope, slope of a line, equation

An airplane cruises 1 kilometer in 1/12 of a minute. What is its cruising speed?
Rasek [7]

Answer:

The airplane is cruising at 200 metres per second.

Step-by-step explanation:

The speed of the object can be got by dividing the distance it travelled by the time taken to travel that distance.

For us to get the accurate cruising speed, we will have to convert all units to their S.I form

Distance - 1 kilometer = 1 X 1000 metres = 1000 metres

1/12 of a minute = 1/12 X 60 = 5 seconds.

Therefore the speed = distance / time

= 1000/5 = 200m/s

The airplane is cruising at 200 metres per second.
