Let point C has coordinates 
Consider vectors
Since the ratio AB to BC is 1:4, you have that
Find 
and 
Answer: C(4,-6)
Let's solve for x.
5x+15y=12
Step 1: Add -15y to both sides.
5x+15y+−15y=12+−15y
5x=−15y+12
Step 2: Divide both sides by 5.
5x

=
−15y+12

Answer:
x=−3y+12/5
Let's solve for y.
5x+15y=12
Step 1: Add -5x to both sides.
5x+15y+−5x=12+−5x
15y=−5x+12
Step 2: Divide both sides by 15.

The <em><u>correct answer</u></em> is:
c)75.4 to 94.6
Explanation:
The formula for a confidence interval is:
,
where μ is the mean, z is the z-score associated with the level of confidence we want, σ is the standard deviation, and n is the sample size.
Our mean is 85, our standard deviation is 12, our sample size is 6, and since we want 95% confidence, our z-score is 1.96:
Answer:
t = -2
Step-by-step explanation:
5t - 26 = 18t
Add 26 to both sides:
5t - 26 + 26 = 18t + 26
Simplify:
5t = 18t + 26
Subtract 18t from both sides:
5t - 18t = 18t + 26 - 18t
Simplify:
-13t = 26
Divide both sides by -13:
-13t/-13 = 26/-13
Therefore:
t = -2
