Please help this hurts
Svetllana [295]

Answer:

6x - 11y = -13 is the answer.

Step-by-step explanation:

Let's plug in the points to see what sticks.

Start with (-4, -1)

1) 11x - 6y = 11(-4) - 6(-1) = -44 + 6 = -38 \neq 13

2) 6x - 11y = 6(-4) - 11(-1) = -24 + 11 = -13

3) 6x - 7y = 6(-4) - 7(-1) = -24 + 7 = -17 \neq 17

4) 6x - 11y = 6(-4) - 11(-1) = -24 + 11 = -13 \neq 13

The only one that fits is #2.  Let's try the other point to be sure.

2) 6x - 11y = 6(1.5) - 11(2) = 9 - 22 = -13

How many whole minutes does it take 10000 viruses to grow to 1 million if their population doubles every 15 minutes?
nikitadnepr [17]
<span>Let's solve how many whole minutes does it take 10 000 viruses to grow to 1 million if their population doubles every 15 minutes.
=> 10 000 x n = 1 000 000 
=> 1 000 000 / 10 000 = 100 times 
=> 100 times * 15 minutes = 1500 minutes to make 1 million viruses
