Answer:
cannot
not constant
Step-by-step explanation:
1st rate of change is 5 - (-1) / 4 - 2 = 6 / 2 = 3
2nd rate of change is 15 - 5 / 6 - 4 = 10 / 2 = 5
3rd rate is 29 - 15 / 8 - 6 = 14 / 2 = 7
cannot be modeled into a linear equation
rate of change is not constant
25
it's because 5 is squared so 5x5 is 25 and x squared
-20.00% is the percent decrease
∠1 + ∠3 + 90° = 180°
∠1 + ∠3 = 90°
∠3 = ∠4 (vertically opposite angles)
∠1 + ∠4 = 90°
Therefore, the answer is ∠1 + ∠4
