From the question
We are given the points
Finding the slopre, m
Slope is calculated using
From the given points
Therefore,
Therefore, m = -8/3
The next thing is to find
A slope parallel to m
For parallel lines, slopes are equal
Therefore,
Next, we are to find
A slope perpendicular to m
For perpendicular lines, the product of the slopes = -1
Therefore
Hence,
Therefore,
Next, we are to find the distance KP
Using the formula
This gives
Therefore,
Next, equation of the line
The equation can be calculated using
By inserting values we have
Therefore the equation is
Answer:
Step-by-step explanation:
One approach would be to begin the indicated multiplication: Multiply a² by a, obtaining a³, which is the first term of the product a3 – a2b + ab2 + a2b – ab2 + b3. Please use " ^ " to indicate exponentiation, or (²) or (³):
a(a² - ab + b²) = a³ (plus 2 more terms, which are -a²b and ab²).
Here we are applying the distributive property of multiplication.
Looking at the info that is given it gives you the answer. If you were trying to find how much more he needs you need to know,
1: How much the music player is.
2: How much you already have.
3:How much you get each week.
So the answer would be C.
