The answer is C) 10x + 330 ≤ 600.
We use the ≤ since you are allowed to use the 600th minute.
When we subtract 330 from both sides, it makes a bit more sense
10x ≤ 270
270 is the number of minutes left your plan since you've already used 330, and you have 10 days left in the month.
Answer:
-x/x^2-1
Step-by-step explanation:
-x^2+x/x^3-x^2-x+1
x(-x+1)/(x+1)(x-1)(x-1)
-x/x^2-1
Since it's isosceles, ∠ABC = (180-30) / 2 = 75
Answer:
Never
Step-by-step explanation: If two points are on the same plane but a line containing those two points is not on the same plane, the statement will never be true. Picture a cube and on one face of the cube lies two points, if there is a line containing those points, the line also has to be on the same side or face. It will always run parallel to the same side but will also always be touching that side.
