QuestionEvaluate the expression for $q=-5$ and $r=-3$ : $q r + 19 q =$

Studdy Solution

STEP 1

Assumptions1. The value of $q$ is $-5$ . The value of $r$ is $-3$

STEP 2

First, we need to substitute the given values of $q$ and $r$ into the expression.
$q r+19 q = (-5)(-) +19(-5)$

STEP 3

Next, we perform the multiplication operation.
$(-5)(-3) =15$ $19(-5) = -95$ So, the expression becomes $15 -95$

STEP 4

Finally, we perform the subtraction operation.
$15 -95 = -80$ So, the value of the expression $qr +19q$ for $q=-$ and $r=-3$ is $-80$ .
