Answer:
A
Step-by-step explanation:
There is four graphs that are given to you and you must identify which one is logical. For you I'll explain how this works. Suppose you rented a bus but you went by yourself so that means you'll have to pay the full 400. However, if you have a buddy then you'll have to pay 200 while your buddy pays the other 200.
Basically 400/x
x=the amount of people going on the trip.
The reason why it's not C since you'll notice that the 3rd dot nearest to the left is 200 which 200 times 3 doesn't equal up to 800.
3x^2 -2root(6)x + 2 = 0
(root(3)x)^2 -2[root(3)x]root(2)+ (root(2))^2 = 0
let a = root(3)x and b = root(2)
a^2 -2ab + b^2 = 0
(a - b)^2 = 0
by the null factor rule,
a - b = 0
sub back in a and b
root(3)x = root(2)
x = root(3)/root(3)
2 is the only number (other than 1, but in most cases 1 does not count) that goes into both 48 and 46.
48 / 2 = 24
46 / 2 = 23
Because of the fact that 48 and 46 are only two numbers apart, it would be impossible for any number greater than two to divide evenly into both.
Y equals 12 is the answer
