Answer: Choice D) earns 5 times as many points compared to previous level
Reasoning:
Let's say she's at level x = 1. That means she earns y = 5^x = 5^1 = 5 points.
At level x = 2, she earns y = 5^x = 5^2 = 25 points
When x = 3, we have y = 5^x = 5^3 = 125 points
And so on. Each new level earns her 5 times as many points as the previous level.
Answer:
step below
Step-by-step explanation:
5 - 3x ≥ 11 x≤ -2 ....4 (bottom)
1 + 3x ≥ -5 x≥ -2 ....3 (3rd level)
5x + 7 ≥ 17 x≥ 2 ....1 (top)
2x + 1 ≤ 3 x ≤ 1 ....2 (2nd level)
