Answer:

(2,16)

Step-by-step explanation:

Step 1: Substitute -x+18 for y in y=8x:

-x+18=8x <em>Add X to both sides</em>

9x=18 <em>Divide 9 by both sides</em>

x=2

y=8(2)<em>Plug in the new value for x(which is 2) into one of the equations</em>

y=16

(2,16)

Hope this helped, good luck!

Answer:

(2,16)

Step-by-step explanation:

y=-x+18

y=8x

8x=-x+18

8x+x=9x

-x+x=0

9x=18

9x/9=x

18/9=2

x=2

y=8(2)

y=16

Which symbol correctly compares these two fractions?<br> 4/7 and 8/16
WITCHER [35]

Answer: 4/7 > 8/16

Step-by-step explanation:

Draw each fraction on a fraction bar (similar to a Hersey's Bar each fraction bar being the same length just broken up differently to represent each fraction) and you will see that 4/7 is bigger than 8/16.
