Answer:
x = 3
Step-by-step explanation:
The formula for the axis of symmetry is x = -b/(2a).
Here, a = -2 and b = 12, so the axis of symmetry is
-12
x = --------- = 3 => x = 3
2(-2)
Answer:
write an answer
Step-by-step explanation:
Biased, because there is only survey of one group of people (one grade, one class). The sample (the class) is too small compared to the population (assuming it’s an average school size). You will end up with less than 1 percent of the population size thus the survey is not reliable information.
Just show how you dived the equation and found the X
2.875 is 69/24 as a terminating decimal
