<span>Linear relations are not functions when they appear graphically as:
Vertical lines
One x not one y</span>
Take the LCM of the three numbers. Since 2 is a multiple of 4, you can ignore the two and just take the LCM of 4 and 3.5. Since 3.5 is a decimal, the LCM is just 3.5*4 which is 14. That is how many minutes after 8:00 they will flash together again.<span />
Guess this is how it should look like, not sure what the instructions on drawing an x through the segments mean, but hope this helps!
2x + 2(5+x)=10
2x+10+2x=10
4x+10=10
4x=0
X=0
The height of plant y =x+25
