Answer:
1/9
Step-by-step explanation:
1/9 is a fraction, so it is rational.
SO SORRY I ANSWERED ON THE OTHER ONE! The answer is C. This line has a negative slope, and the ending number tells you the y-intercept.
Answer:
C. line d
Step-by-step explanation:
Two parallel lines are lines that do not meet even with continuous extension of their length. While two lines are perpendicular when they form a right angle to each other at the point where they meet.
In the given question, the only figure that would be parallel to line c is line d. Line a is not parallel to line c (since it is slightly diagonal, it would intersect line c at a point) and line B is perpendicular to line c (since it is horizontal to plane Q), same as plane Q. So that lines c and d are parallel to each other.
Answer:

Step-by-step explanation:
The given equality is

Take the term
to the left hand side. This means the term
will be divided by 

Now since both the numerator and denominator have negative sign the value of fraction will be positive.

Now
and 

So, the missing factor
