Question

If a=y²-xz/5, find the value of a when x=2, y=-1 Ans z=-3.​

Answer 1

Answer:

The answer will be 11 / 5.

Step-by-step explanation:

We have given;

                      x=2;

                      y=-1 ;

                      z=-3;

We are asked for a in the equation;

                          a=y²-xz/5;

Put the given values inside the equation;

                             a = (-1)^2  - (2)(-3) / 5;

                                = 1 - (-6) / 5;

                                = 1 + 6 / 5;

                                = 11 / 5;

That's all.
