Answer:
one solution
Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.

Answer:
2/6 (1/3)
12 gallons
Step-by-step explanation:
3) 1/2x1/3=1/6, so he'd used 1/6 of a tank.
1/2-1/6=
3/6-1/6=2/6. So the tank was 2/6 full, or 1/3 full when he got home.
4) If it's 1/3 full and has 4 gallons, it can hold 12 gallons. (4x3)
<h2>Number of bacteria after 6 days is 2313</h2>
Step-by-step explanation:
Population after n days is given by
![P_n=P_0(1+r)^n](https://tex.z-dn.net/?f=P_n%3DP_0%281%2Br%29%5En)
Initial population, P₀ = 1000
Increase rate, r = 15 % = 0.15
Number of days, n = 6
Substituting
![P_n=P_0(1+r)^n\\\\P_6=1000(1+0.15)^6\\\\P_6=1000(1.15)^6\\\\P_6=1000\times 2.313\\\\P_6=2313](https://tex.z-dn.net/?f=P_n%3DP_0%281%2Br%29%5En%5C%5C%5C%5CP_6%3D1000%281%2B0.15%29%5E6%5C%5C%5C%5CP_6%3D1000%281.15%29%5E6%5C%5C%5C%5CP_6%3D1000%5Ctimes%202.313%5C%5C%5C%5CP_6%3D2313)
Number of bacteria after 6 days = 2313
