The point $(p,9)$ lies on line $k$ shown here. What is the value of $p$?
blagie [28]

Answer:

(10,9) P=10

Step-by-step explanation:

find the slope first: y2-y1/x2-x1=(3-1)/1-(-2)=2/3

y=2/3x+b

find b:

3=2/3(1)+b

b=3-2/3

b=7/3

now we find P

(p,9) input the y in the equation

y=2/3 x+7/3

9=2/3x+7/3

9-7/3=2/3x

x=10

vitfil [10]

Answer:

The latest possible date is December, 14th.

As the weeks have seven days, the first Friday will be between 1st and 7th of each month. So, the latest first Friday will be 7th. Therefore, the latest second Friday will be 14th.
