Which of the following valued of x is not in the domain of f(x) = x+3 / x-7
1 answer:
Answer:
x = 7 is not there in the domain of the function.
Step-by-step explanation:
The given function is f(x) =
We have to find out which all values are not there in the domain of the function.For the function to become not defined the function should have infinite value and this happens when the denominator becomes zero.
In the given function for the denominator to become zero , the value of x must be 7.
For all other values of x , the function is defined.
Hence , the domain of x is all real numbers except 7.

Answer:
Step-by-step explanation:
Let x be the number of buses and y be the number of vans.
We know that there are 5 more buses than vans, therefore, we can set up:
Since a bus transports 55 people and a van transports 12 people, therefore, we can set up:
Now lets solve the above two equations together by substitution
Total number of students and teachers who rode to the zoo in buses
Total number of students and teachers who rode to the zoo in vans
