Are the following functions linear or nonlinear?
exis [7]

Answer:

The chart is linear, the graph is not.

Step-by-step explanation:

Because the graph is curved and not straight, it is non-linear. You can also tell that this is non-linear because the rate of change, or slope, is inconsistent. The chart is linear because it has a consistent slope. I hope this helps, have a nice day. :-)

Answer:

-\dfrac{3}{5}

Step-by-step explanation:

1. Find the numerator:

\dfrac{1}{3}-\dfrac{5}{6}=\dfrac{1\cdot 2}{3\cdot 2}-\dfrac{5}{6}=\dfrac{2}{6}-\dfrac{5}{6}=\dfrac{2-5}{6}=-\dfrac{3}{6}=-\dfrac{1}{2}.

2. Simplify the fraction:

\dfrac{-\frac{1}{2}}{\frac{5}{6}}=-\dfrac{1}{2}\cdot \dfrac{6}{5}=-\dfrac{3}{5}.
