for number 2, i thought it was y = 5x because if you multiply 5 by any of the numbers in the x colum, it equal y

Also for number 3, could you further explan, are you saying the answer is zero?

As for number one, is the answer 1/x-3 where x does not equal 3,

For number 2, if you have a table with a column for x and another column for y, and all the y-values are obtained by multiplying the x-values by 5, then the equation representing that relationship would indeed be y = 5x. So, your understanding is correct.

Regarding number 3, without any context or further information provided, it is not possible for me to determine the exact answer. However, if you are referring to the solution of an equation or expression, it may be necessary to evaluate the given equation or expression. If you can provide the specific equation or expression in question, I can assist you further.

Regarding number 1, the answer you provided is close, but not entirely correct. If you have an expression of the form 1/(x-3), it represents a rational function where x cannot be equal to 3 due to division by zero. In other words, the solution for x should not be equal to 3 for the expression to be defined.
