Indicate whether each statement is always true (a), sometimes true (s), or never true (n).
a. if two lines are perpendicular to the same plane, the lines are parallel.
b. two planes can intersect in a point.
c. two lines parallel to the same plane are perpendicular to each other.
d. if a line meets a plane in one point, then it must pass through the plane.
e. skew lines can lie in the same plane.
f. if two lines are parallel to the same plane, the lines are parallel.
g. if two planes are parallel to the same line, they are parallel to each other.
h. if two lines do not intersect, they are parallel.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
