The ordered pairs (1, 3), (2, 9), (3, 27), and (4, 81) represent a function. Write a rule that represents this function.

1 answer:

4 0

Let x be the first number each pair and y is the second of each As you see 1x is 3y
And. 2x is 3*3y= 9y
3x = 3*3*3y= 27y

Last 4x =3*3*3*3y= 81y

So y = 3^x

There are twelve people on the jury there were 4more man than women how many man were there/

irina1246 [14]

$x-the \ number \ of \ women \\ x+4 -the \ number \ of \ men \\\\ x+x+4=12 \\\\ 2x+4=12 \\\\ 2x=12-4 \\\\ 2x=8 \\\\ \boxed{x=\frac{8}{2}=4 \ women} \\\\ x+4= \\\\ = 4+4\to\boxed{8 \ men}$

The graph of which of the following equations is a line parallel ot the graph of x-5y=8

kvv77 [185]

Since you don't show the graph, all I can do is to tell you how to identify which function is parallel to the x-5y=8.

First let's rearrange the function.

x-5y=8

5y=x-8

y=1/5x-8/5.

Thus, it gives us the slope of the function, which is 1/5.

And the function that is parallel to the graph would have the SAME slope. Which is 1/5. So all you need to do is to find which function has the SAME SLOPE, in this case: 1/5.
