Answer:
Solution to determine whether each of these sets is countable or uncountable
Step-by-step explanation:
If A is countable then there exists an injective mapping f : A → Z+ which, for any S ⊆ A gives an injective mapping g : S → Z+ thereby establishing that S is countable. The contrapositive of this is: if a set is not countable then any superset is not countable.
(a) The rational numbers are countable (done in class) and this is a subset of the rational. Hence this set is also countable.
(b) this set is not countable. For contradiction suppose the elements of this set in (0,1) are enumerable. As in the diagonalization argument done in class we construct a number, r, in (0,1) whose decimal representation has as its i th digit (after the decimal) a digit different from the i th digit (after the decimal) of the i th number in the enumeration. Note that r can be constructed so that it does not have a 0 in its representation. Further, by construction r is different from all the other numbers in the enumeration thus yielding a contradiction
60 times 6 equals 360.
So the answer is $360
Answer:

Answer:
Step-by-step explanation:
The easiest way to complete this is too use this data and put it into point-slope form. This is written as, y-y1=m(x-x1)
In this equation y1 is the y- coordinate of your point and x1 is the x-coordinate. M in this case would also be known as the slope.
Now we can submit our data-----
y-4=-5(x-5) -------- simplify
y-4=-5x+25 --------
y=-5x+28
