Answer:
If you write a number as a fraction, that number's reciprocal is a fraction with the numerator and the denominator switched around. For example, the reciprocal of
4
5
is
5
4
. Some general rules to keep in mind:
-If the fraction has a
0
in the numerator, the reciprocal is undefined.
-If the fraction has a
0
in the denominator, the fraction itself is undefined. Thus it can't have a reciprocal.
-Any other fraction has exactly one reciprocal.
Finally, the reciprocal of a reciprocal is the original fraction. This means if you flip a fraction's numerator and denominator, and then flip them back, you get the number you started with.
Step-by-step explanation:
The answer would be the last one because function one has a slope of 1/2 (use rise/run) and function 2 has a slope of 2 (subtract the 2nd y value by the one above it)
Answer:
3.91
Step-by-step explanation:
That would be 1/5 in simplest form you can divide both numbers by 12 and when you do you get 1/5. Hope this helps!
