1980 should be ur answer BUT if you want it estimated it would be 1800
Answer:
The answer to your question is: 
Step-by-step explanation:
7.63636364 so basically 7.63 repeating
We have two options in the case of the equation for parabola y=ax²:
1) in the case that a is negative the parabola opens down
2) in the case that a is positive the parabola opens up
So the correct answer is: if a is positive, the parabola opens up.
1. 13.75= 0.25b +0.50
-0.50 -0.50
13.25 = 0.25b; divide both sides by 0.25 to isolate b and you get:
53 = b
2. 10w + 4w = -84
Add like terms!
14w = -84; divide both sides by 14 to isolate w and you get:
w = -6
