Question

if a =y2-xz/5 ,find the value of a when x= 2 y =-1 and z=-3

Answer 1

Step-by-step explanation:

Given that,

a = y² - xz/5 ----------(i)

and x = 2, y = -1, z = -3

Now putting the value of x, y, and z in the equation (i)

We get,

a = (-1)² - {(2*(-3))/5}

  = 1 - {(-6)/5}

  = 1 + 6/5

a = 11/5

∴$a=\frac{11}{5}\\=>a=2\frac{1}{5}$
