Your goal requires you complete the distance in 2 minutes. If you travel at half the target speed, you will have used up the allowed time traveling the first half of the distance.
You need to travel the second mile at infinite speed to average 60 mph.
-3x-2x+12x+5x=-9
-5x+12x+5x=-9
-5x+17x=-9
-12x=-9
x=-9+12
×=-3
Answer:
whats the question
Step-by-step explanation:
The answer is b. you would subtract 1.25 from both sides which would make the equation k=11.25.
Answer:
no
Step-by-step explanation:
If x = 3 is a zero, then f(3) = 0
f(3)
= 4
- 3³ - 52(3)² - 35(3) + 12
= 324 - 27 - 468 - 105 + 12
= - 264
Since f(3) ≠ 0 then x = 3 is not a zero of f(x)
