I think answer A should be the correct answer
Answer:
<u>They are parallel.</u>
Step-by-step explanation:
L1: x − y = 2 ; or x-y-2=0
L2: y = x + 1; or x-y+1=0
<em>The slope of the line L: ax+by+c=0 is m= -a/b.</em>
L1: x-y-2=0=><em> m1=(-1)/(-1)=1</em>
L2: x-y-1=0=> <em>m2=(-1)/(-1)=1</em>
L1 and L2 have the same slope; m1=m2=1
=> L1 and L2 are parallel.
10/5 = 1/x
cross multiply
10x = 5
x = 5/10
x = 1/2...u need 1/2 gallon per fish
