Find the equation of the lines perpendicular and parallel to 2x-3y=8 line through the point (-2,-4)
marysya [2.9K]

Answer:

y= -1.5x-7 is the equation of the perpendicular line

Here's why:

when we convert 2x-3y=8 to standard form, we get y= 2/3x-8/3. This means the perpendicular line will have a slope of the negative reciprocal of the original one, so the perpendicular slope is -1.5. When we substitute the points (-2,-4) into the equation y=-1.5x+b, we get a b value of -7. So the perpendicular line equation is y= -1.5x-7. You can't the parallel line equation with the points (-2,-4) as it is part of the line 2x-3y=8.

The distance Train A travels is represented by d = 67t, where d is the distance in kilometers and t is the time in hours. The di
Thepotemich [5.8K]

Answer:

Train A's unit rate is 67 km per hour.

Train B's unit rate is 75 km per hour.

Train B is faster than Train A

Step-by-step explanation:

Train A

Distance traveled by Train A is represented by :

d=67t

where d represents distance traveled in kilometers and t is the time in hours.

To find the unit rate of Train A, we will plugin t=1 and get the distance traveled by Train A in 1 hour which will be the unit rate of Train A in km/hr.

d=67(1)

d=67

So, distance traveled by Train A in 1 hour = 67 km

∴ Train A's unit rate is 67 km per hour.

Train B

For Train B, we are given the table for the time in hours and distance traveled in that duration.

Taking time =2 hours the distance traveled by Train B= 75 km

To find distance traveled in 1 hour we apply unitary method.

2\ hr = 150\ km

So 1\ hr = \frac{150}{2}\ km = 75\ km

So, distance traveled by Train B in 1 hour = 75 km

∴ Train B's unit rate is 75 km per hour.

Difference in units rates = 75-67=8\ km/hr

On comparing their unit rate i.e. the speed of the trains we find out that Train B is faster than Train A by 8 km/hr
