7- 5n=6+6(n+2)
7- 5n=6+6n+12
7 -5n=18+6n
5n-6n=18-7
-11n=11
n=-1
1 Subtract 2 from both sides
-3y≤17−2
2 Simplify 17−2 to 15
−3y≤15
3 Divide both sides by -3
y≥−15/3
4 Simplify 15/3 to 5
y≥−5
Where's the graph at? Did you forget to place?
A) The area of a square of side 1 that is outside a circle of radius 1 is (1 -π/4), so the probability of interest is
.. p(outside unit circle) = 1 - π/4
b) The sets of numbers such that 3y>x is fill an area that is 5/6 of all sets of numbers (x, y) in the interval [0, 1].
.. p(3y > x) = 5/6
