Answer: 25
Step-by-step explanation:
7 + -6(-3)
7 + 18 = 25
The answer is 5, 2. 2(5)-2=8 and 2=5-2
Answer: t = 2698 as question is written. Just subtract 14 from both sides. There is either a typo in the question or the answer choices.
Step-by-step explanation:
Answer:
2.5 seconds since the first ball was hit.
Step-by-step explanation:
The equations that model the heights are:
When the balls meet, both heights are equal, therefore:
-16t² + 56t = -16t² + 156t - 248
-16t² + 56t + 16t² - 156t + 248 = 0
- 100t + 248 = 0
248 = 100t
248/100 = t
t = 2.48 ≈ 2.5
