Answer:
3.6 units (nearest tenth)
Step-by-step explanation:
distance formula
= 
Thus, distance between the 2 points
= √[(5 - 3)² + (1 - 4)²]
= √[ 2²+ ( - 3)²]
= √13
= 3.6 units (nearest tenth)
Answer:
Let's see what you can do with parallel and perpendicular. In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts. In other words, perpendicular slopes are negative reciprocals of each other
Answer:
18
Step-by-step explanation:
To continue where you left off, ...

The square root of 324 is 18.
1. y=-3/4x+23/2
2. y=-x/3+10/3
Multiply both the numerator and denominator by
, which is called the "conjugate" of
:

Why do we pick this number? Recall the difference of squares factorization:

Now replace
and
. Then

So in your fraction, you end up with

Finally, just expand the product.
