Answer:
15x
Step-by-step explanation:
5 (x+2x)
5 (3x)
15x
Hey there! The sum of (3x - 6) and (5x + 8) is 8x + 2.
Yes. A rectangle can have any amount of width.
We can assume the x value is time, and the y-value is fish population.
The best answer is the third option, a line going through 0,5 and 7,5. We don't know if Molly arrived at the dorm with fish, but we know that during the 8 months, her fish population stayed the same at 5 fish.
The first option features a y value of 8, so we know that's wrong. She never had more than 5 fish.
The second option is wrong for the same reason (y values of 6 and 9)
The fourth option in wrong because the fish population did not fall to 2 after 7 months.
