Answer: slope of line n = -3
Reason: Parallel lines have equal slopes, but different y intercepts.
Straight away it can't be A or B because the last/ones digits aren't multiples of 5.
For something to be divisible by 9, add all the digits up and see if it is a multiple of 9:
This works for both C and D, as both numbers have digits which add up to 18.
However, only C is divisible by 6. D is an odd number and hence it is eliminated. For something to be divisible by 6, it must be divisible by 2 (an even number) and 3 (digits add to a multiple of 3). C does both.
Hence C is the answer.

Answer:
Step-by-step explanation:
Null hypothesis should be: The average woman's leg hair grows an eighth of an inch per month: u = eighth of an inch
Alternative hypothesis: The average woman's leg hair growth is not an eighth of an inch per month after treatment: u ≠ eighth of an inch
This test after carrying out its treatment will be able to determine if the drug was effective or not
Answer:
y-2=2(x-1)
Step-by-step explanation:
Pick any two points from the line (example: (1,2) and (2,4))
Find the slope of them
Reminder: Slope is changes in y/changes in x or y2-y1/x2-x1
In this case, m= 4-2/2-1 which is 2
Now to use slope point form, chose any point and substitute it into this equation:
y-y1=m(x-x1)
Substituting it would get
y-2=2(x-1)
Or
y-4=2(x-2)
Answer:
Short answer: D) 15
Step-by-step explanation:
Parallel lines in this kind of triangle are always in a strict ratio of small to large or large to small based on how you look at it.
So we have 4cm to 6cm, which is 2:3 ratio. We know the smaller side, but want the larger side, so we can set up 2/3 = 10/?
the ? is 15.
