If distinct planes r and s are both perpendicular to line l , which is always true?
1. plane r is parallel to plane s
2. plane r is perpendicular to plane s
3. planes r and s and line l are all parallel
4. the intersection of planes r and s is perpendicular to line l

Option 1 is correct.

Step-by-step explanation:

Let there is a line A which is perpendicular to line L at point O.

Now, rotating line A about point O by 360° will give the plane R.

So, plane R is perpendicular plane to line L.

Again, let there is a line B which is perpendicular to line L at point P.

Now, rotating line B about point P by 360° will give another plane S.

So, plane S is perpendicular plane to line L.

Since line A and line B are parallel (As they are perpendicular to the same line L) so, plane R containing line A and plane S containing line B will also be parallel to each other.  

Hence, option 1 is correct. (Answer)

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

black/brown

step-by-step explanation:

well, you see here, jamal was born to 2 parents, his mother who he lives with and his father who left at a young age and who happens to be younger than him. he stole cookies because he has to steal food due to the fact that he spends his government poverty checks on pot and women.
