Transcript text: What are the correct steps to solve this inequality, and which is the correct graph solution? (The green region is the shaded area.)
\[
-4 x-46<-38
\]
(1 point)
Add 46 , divide by -4 , flip the inequality sign, $x>-2$
Add 46 , multiply by -4 , flip the inequality sign, $x>-2$
Add 46 , divide by $-4, x<-2$
Solution
Solution Steps
Step 1: Add 46 to both sides
$-4x - 46 + 46 < -38 + 46$
$-4x < 8$
Step 2: Divide both sides by -4 and flip the inequality sign
Since we are dividing by a negative number, we flip the inequality sign.
$-4x/-4 > 8/-4$
$x > -2$
Step 3: Graph the solution
The solution is $x > -2$. The graph should have an open circle at -2 and be shaded to the right. This corresponds to the first answer choice.
Final Answer:
Add 46, divide by -4, flip the inequality sign, $x > -2$. The graph has an open circle at -2 and is shaded to the right.
