The middle of PQ is (9/2,1/2,2)
The sphere has for equation (x-9/2)²+(y-1/2)+(z-2)²=R²
and P is a point of the sphere so R=(-1/2)²+(3/2)²+(-1)²=R²=7/2
We have such equation
5x-3y=12 /-5x (subtract 5x both sides)
5x-5x-3y=12-5x
-3y=-5x+12 /:3 divide both sides by 3
-y=

/*(-1) multiply both sides by -1
y=-

y=

- its the answer
Answer:
Wheres the graph? Or is the numbes that are on the graph im really confused?
Answer:
NO=22.6
Step-by-step explanation:
NO=MO+MN
after substituting MO and MN,
NO=15+7.6
=22.6
also, the problem says to answer with only the number, so just type 22.6!
