Question

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

Answer 1

Answer:

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

∴\begin{gathered}a=\frac{11}{5}\\= > a=2\frac{1}{5}\end{gathered}

a=

5

11

=>a=2

5

Answer 2

Answer:

Thanks for your question...

Your required answer :

Given question ,

• $a = \frac{ \: y {}^{2} - xz}{5}$

Given value ,

• x = 2
• y = - 1
• z = - 3

Solution ,

• $a = \frac{ (- 1) {}^{2} - 2 \times ( - 3) }{5}$
• $\frac{1 + 6}{2}$
• $\frac{7}{2}$
