Question

Evaluate 12x-3ywhenx=-1/4andy=3

Answer 1

To evaluate the function 12x -3y when x = -1/4 and y = 3, we need to substitute each of the values into the function, do the necessary operations to have the final result. Therefore, we can proceed as follows:

`12x-3y\Rightarrow12\cdot(-(1)/(4))-3\cdot(3)=-(12)/(4)-9=-3-9=-12`

Thus, the value for the given expression is -12 when x = -1/4 and y = 3.
