QuestionEvaluate $10 - y^{2}$ for $y = 3$ . Which is the correct substitution? A) $10 - 3^{2}$ B) $10 - 2^{2}$ C) $10 - (2)^{3}$

Studdy Solution

STEP 1

Assumptions1. The expression to be evaluated is $10-y^{}$ . The value of $y$ is given as $3$

STEP 2

We need to substitute the given value of $y$ in the expression $10-y^{2}$ .

STEP 3

Substitute $y=3$ in the expression $10-y^{2}$ .
$10-3^{2}$

STEP 4

Evaluate $3^{2}$ .
$3^{2} =9$

STEP 5

Substitute $3^{2}$ with $9$ in the expression $10-3^{2}$ .
$10-9$

STEP 6

Calculate $10-9$ .
$10-9 =1$ The correct substitution for evaluating $10-y^{2}$ when $y=3$ is $10-3^{2}$ which equals to $1$ .
