Intercept ⇒ when f(x) = 0
f(x) = 3x² - 12x - 1
3x² - 12x - 1 = 0
Answer: The two x-intercepts are (4.08, 0) and (-0.08, 0)
Answer:
4.30 and 0.70 if you round of to the nearest tenth
Step-by-step explanation:
pls mark as brainliest lol
Answer:
0.008
Step-by-step explanation:
Answer:
78 miles per hour
Step-by-step explanation:
Formula for speed is Distance divided by Time. (D/T)
The distance between Station A and Station C can be found be adding the distance from A to B and B to C. (20.8 Miles)
Same concept would go for the time.
Time to get from A to B added with B to C. (16 Minutes)
However, the time is in minutes and the question calls for hours. Divide 16 by 60, you get around 0.27.
20.8 divided by 0.27 would be around 77.9, or 78 miles per hour.
Hope this helps :)
As we know, the square root of negative numbers.
Hence, the x must be a positive value and greater than 0.
So, x:x∈[0,∞)
subtracting 3 from both sides
x:x∈[-3,∞)
