Answer: All the time.
Step-by-step explanation:
Here,
x= elapsed time
y = number of gallons of water in tank.
For tank A,
3y=750x+300
Divide both sides by 3, we get
y= 250x+100 ...(i)
For tank B,
4y=1000x+400
Divide both sides by 4, we get
y=250+100 ...(ii)
From (i) and (ii) it can be seen that both the function are same.
That means the amount of watre will be same for every value of x, where x ≥0
Answer:
x=-1
y=-3
Step-by-step explanation:
3x-2y=3(1)
5.(1) <=> 15x-10y=15 (2)
15x-4y=-3 (3)
(2)-(3) <=> -6y=18
Answer:
option a
Explanation:
AD and DE are perpendicular lines, meaning they are at a 90° angle. likewise, AD and AB are also perpendicular lines. this means that there are 90° angles at ∠ADE and ∠DAB.
since both DE and AB are perpendicular to the same line and are positioned at the same angle away from it, they are parallel lines.
i hope this helps! :D
The answer will be option 6. angle.
