What is not perpendicular to 7x +2y= 3

Mathematics

vfiekz [6]3 years ago

Every line that does not have the slope of 2/7 is perpendicular to this line.

In order to find this fact, we first must find what is perpendicular. To do that, we first have to find the slope of this line. We can do this by solving for y.

7x + 2y = 3

2y = -7x + 3

y = -7/2x + 3/2

Now we can take the slope of -7/2 and flip and negate it. This will give us the perpendicular slope (2/7). Now we know any line that does not have this slope is not perpendicular to this line.

line BF contains point B and as you can see, it not only does not intersect CD, but it also goes in a different direction, thus, these lines are in different planes, thus, the lines are skew.

So line BF is the correct option.

<h3>Which line contains point B and seems to be skew to CD?</h3>

We say that two lines are skew if the lines are not parallel and do not intersect.

For example, the line BC clearly contains the point B, but by looking at the diagram we can see that the line BC intersects the line CD, so these lines are not skew.

In other hand, line AB also contains point B, but this line is parallel to CD, so we discard this one also.

Line AE does not contain the point B, so also can be discarded.

Finally, line BF contains point B and as you can see, it not only does not intersect CD, but it also goes in a different direction, thus, these lines are in different planes, thus, the lines are skew.

So line BF is the correct option.

Answer:

x= 99

Step-by-step explanation:

first we open brackets

6x+36=7x-63

transpose

6x-7x= -63-36

-x=-99

the signs cancel each other so

x= 99
