Study the meaning of these symbols and pick up the correct answer from the answer choices for each of the questions below:
`x - y = z` implies

Options

A. `x + y - z`
B. `x Delta y xx z`
C. `x + y phi z`
D. `x + y xx z`

Answer

B

Explanation

According to the meaning of the given symbols , `x - y = z implies x = y gt z`
Using the proper symbols in option (b) , we get
`x Delta y xx z implies cancelgt y cancellt implies x = y gt z` .
Therefore `x-y = z implies x Delta y xx z`.
