Answer:
X=8
Step-by-step explanation:
........... ....................... . . ........
3x+2y=11
y=5x-1
Substitute the y in the first equation:
3x+2(5x-1)=11
y=5x-1
3x+10x-2=11
y=5x-1
13x=13
y=5x-1
Now substitute the x to find the y:
x=1
y=5-1=4
Answer:
One solution
Step-by-step explanation:
(given)
∴ There is only one solution to this equation since 
can only equal to 
to satisfy the equation.
Hope this helps :)
You would put the number of bottles sold on the "x" axis and the cost on the "y" axis. If you graph properly it will show a linear relationship, which means you'll have a line like this ➝ / that corresponds with the data.
