The answer is B
you can substitute the(x,y)in the equation to find out the answer.
For example,Is (3,0) a point on 1/3x+y=15.
By Substitute x=3 and y=0 to the equation
1/3(3)+(0)=1,which is =/=15.
So you know that (3,0) is not a point on the equation
Answer:
im not sure
3. B
Step-by-step explanation:
The answer to the statistics question above would be <span>± 1.27. Thus, the confidence interval for the mean hours devoted to social networking in January is equated to 1.27 above or below. Thus, the true population mean would range around 53.73 to 56.27 hours.</span>
You can use slope formula
think of it as a graph initially you start at point (0,10,000)
then you move to (15 , 7,000)
10,000 -7,000 =3,000
15 - 0 = 15
so 3,000/15 is...
200 ft per minute
since you are moving down it is a negative slope -200ft per min
