The second one because for every x value there is one and only one y value. If you plotted the points and graphed it, you would know it is not a function if it doesn't pass the vertical line test. Notice the same x values show up repeatedly in the other ordered pairs with different y values. Only one y value for every x value
Answer:
4/9
Step-by-step explanation:
The possibilities of transportation: (The first will be for morning, second will be for afternoon)
B, B

T, T
It is clearly seen that there are 9 transportation options.
(Using cab 1 time we have BC, CB, CT, TC. So four of the transportation methods use cab one time.)
Therefore, the probability that she will use a cab only once is 4/9.
Answer:
x=3 5x+2=17
Step-by-step explanation:
5/6 is equal to 10/12 and 3/8 is equivalent to 6/16
We need to simplify this expression:

So, we will call this expression as:

We can write this equation like this:

So, if we simplify it, this can be written like this:
f(x) = 4 but given that the denominator can't be zero, then:

∴
Therefore:
f(x) = 4 if and only if
