What is the value of $\frac{x^{2}}{y}$ when $x = - 4$ & $y = - 2$ ?
$- 8$
$- \frac{1}{8}$
$\frac{1}{8}$
$8$

Short Answer

Expert verified

The correct answer of this question is $A . 鈥� - 8$

Step by step solution

Step 1. Apply the concept of putting the given value of x and y

In this, simply use the concept of putting the given value of x& yin the equation to get the correct answer.

Step 2. Find the solution of the equation

Here, the expression is simplified as:

$\frac{x^{2}}{y} = \frac{{(鈭� 4)}^{2}}{\begin{array}{l} 鈭� 2 \\ = \frac{16}{\begin{array}{l} 鈭� 2 \\ 鈭� 8 \end{array}} \end{array}}$ ( putrole="math" localid="1651690317420" $x = 鈭� 4$ &role="math" localid="1651690390868" $y = 鈭� 2$ )

Step 3. Eliminating the options to get correct one

$- 8$ It is the correct option because after putting the given value of x, yand z the answer is equal to $- 8$
$\frac{- 1}{8}$ It is the incorrect option because after putting the given value of xand ythe answer is not equal to $\frac{- 1}{8}$
$\frac{1}{8}$ It is the incorrect option because after putting the given value of xand y the answer is not equal to $\frac{1}{8}$
$8$ It is the incorrect option because after putting the given value of x and y the answer is not equal to $8$
