It is not linear because x is raised to the second power. Therefore it is not straight and would be kindof like a rainbow cut in half on the graph..

Please answer the following questions: <br><br> 1. 1/2*8=<br> 2. 1/4*4=<br> 3. 1/3*6=
yan [13]
Hey there!

When we multiply fractions and whole numbers, we simply take that whole number and put it over them, and just multiply across. That gives us:

\frac{1}{2}x*8 = \frac{8}{2} = 4

Notice how it's four, because when we have a fraction, we divide. 8 divided by 2 equals four. Next:

\frac{1}{4} *4 = \frac{4}{4} = 1

4/4 is equal to 1 because 4 divided by 4 is one. 4 goes into 4 once. Next, we have:

\frac{1}{3}*6 = \frac{6}{3} = 2

That's because 6/3 = 2.

Hope this helps!
