Answer:
x=2
y= -2.5
Step-by-step explanation:
x int
1.) set y to 0 (5x -4(0)=10
solve for 5x=10
y int
1.) set x to 0
solve for -4y=10
I believe it would be a to X is 20 units because A to B is 10 units so a to X would make sense if it was 20 units hope this helps!
1yd=3ft...so 39ft=(39/3)=13yds
1mins =60seconds
13/60=0.22yds/secs

Otherwise, it would be hard to determine whether his plant growth was because of the soil brand or the different amounts of sunlight and water received
