Write the equation of the line perpendicular to 2x-3y=6 through the point (-2,4)

Mathematics

Answer:

y = -3/2x + 1

Step-by-step explanation:

Perpendicular lines' slope will have the negative reciprocal of the other one's slope.

First, put 2x-3y = 6 into slope - intercept form, so it would be:

-3y = -2x+6\\y = \frac{2}{3}x - 2

This means that the slope of that line is 2/3, so the slope of the perpendicular line would have to be -3/2.

Then, you can put this into point-slope form, so it would look like:

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

y = -\frac{3}{2} x - 3 + 4 \\y = -\frac{3}{2}x + 1

Genrish500 [490]

Answer:

1) 3

2) 1

3) -5

Step-by-step explanation:

The coefficients are the numbers that come before each variable.

The 3 in the first term is in front of the x^2; so the coefficient is 3.

There is no visible number in front of the y in the second term, but there is a y, so we can assume there's at least 1; so the coefficient is 1.

The term in front of x for the third term is -5, so the coefficient is -5.

there are 12 inches in one foot which expression can be used to find the number of inches in 2.5 feet?
valentina_108 [34]
It would be the 1st one ( 12in× 1in/2.5ft) the reason is you want the measurements to match so that way when you solve the equation you are multiply 12 by 2.5 to get the number of inches

A bicyclist heads east at 10km/h. After she has traveled 24.2 kilometers, another cyclist sets out in the same direction going 3
Alona [7]
We know that the first cyclist has traveled 24.2 km at a speed of 10 km/h. Lets use the equation time= \frac{distance}{speed} to find the time of the first cyclist:
t= \frac{24.2}{10}
t=2.42
So, we know that she has traveled for 2.42 hours.
 
We also know that after she has traveled for 2.42 hours another<span> cyclist sets out in the same direction, so if </span>t represents the time of our first cyclist, <span>the time of our second cyclist will be </span>t-2.42.

Now we are going to use the equation distance=(speed)(time) to relate the speeds and times of the two cyclist:
For the first one:
distance=10t equation (1)
For the second one:
distance=30(t-2.42) equation (2)

Replace (1) in (2)
10t=30(t-2.42)
The only thing left now is solve for t:
10t=30t-72.6
-20t=-72.6
t= \frac{-72.6}{-20}
t=3.63

We can conclude that the second cyclist will catch up the first cyclist after 3.63 hours.
