"a town has accumulated 2 inches of snow, in the snow depth is increasing by 4 inches every hour. a nearby town has accumulated 10 inches, and the depth is increasing by two inches each hour in about how many hours will the snowfall of the town's be equal? " !

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

as given ,→planes t and x are parallel.

→plane t contains line a.

→plane x contains line b.

as we know by definition of line , if we take any two points on a plane the line should completely lie on it i. pass through these two points.

out of the four options given it seems that two possibilities might be true.

1. they may be skew lines , so they will never intersect.

2.if lines a and b are parallel, so again they will not intersect.

other two seems incorrect

because if a and b are perpendicular to the plane ,

1. either they will join each other to form a unique line or2. they will never intersect.

there is no possibility that they will intersect at two points.
