Hello,
A=(-4,2)
B=(3,-5)
AB≡y-2=(x+4)(-7)/7==>y=-x-2
Slope of the perpendicular: 1
y-2=(x-1)1==>y=x+1 is the equation of the perpendicular.
Intersection: y=x+1 and y=-x-2 ==>(-3/2,-1/2)=Q
|PQ|²=(-1/2-2)²+(1+3/2)²=25/2
|PQ|=5√2/2≈3.5355339059....

Answer:
pretty easy two
Step-by-step explanation:
ye just look
Start by distributing -8 to (8-3n) and -5 to (n+1). The equation becomes:
-64+24n-5n-5=4n-1-8
Next, you can simplify both sides of the equation. It will look like:
-69-19n=4n-9
Next, add 19n to both sides so you isolate the variable on one side of the equation. You will get:
-69=23n-9
Now, you can proceed to solve this like any other two-step equation. Add 9 to both sides:
-78=23n
Divide both sides by 23:
-3.3913=n
Hope this helps!
Answer: 27/64
Explanation: you multiply 3/4 by 3/4 which is 9/16 then you multiply 9/16 by 3/4 which is 27/64
Hope this helps! :)
