?/0.6=1.4<br>how to show the solution
den301095 [7]
To find the solution to this problem, you would do the opposite of division which is multiplication.

Use the terms you have to plug into your new equation;

0.6 x 1.4 = .84

To check your work you would plug in .84 where the '?' is;

.84/.6= 1.4

There you have the original equation you began with.

Therefore, .84 would be your final answer.

Help me with #1 please :) Is it A?
Hoochie [10]
Yes, you are correct, it is A!

Recall the pencil line test, which is where you go across the x axis (the graph horizontally) and see if the pencil touches any two points at the same time. If it does, then the graph is not a function.

Point being: since question a has a bunch of y values on top of one x value, the pencil would inevitably touch multiple at the same time, hence why it is easy to tell that it is not a function! Hope this helps :)
