Chapter R.13, Problem 1DE

Evaluate.

$57y$, when $y=-8$

To determine

To calculate: The value of the expression $57y$ at $y=-8$.

Answer to Problem 1DE

Solution:

The value of the expression $57y$ at $y=-8$ is $\underset{\_}{-456}$.

Explanation of Solution

Given information:

The provided expressions are $57y$.

The value of the variable is $y=-8$.

Calculation:

Consider the expression,

$57y$

Now, substitute the value $y=-8$ in $57y$

Therefore,

$57y=57\left(-8\right)$

Perform multiplication from left to right as below

$\begin{array}{c}57y=57\left(-8\right)\\ =-456\end{array}$

Hence, the value of the expression $57y$ at $y=-8$ is $-456$.
