question 2
how would you describe the graph of $10.2 - x > 20.8$?
\bigcirc open circle, shaded to the left
\bigcirc closed circle, shaded to the right
\bigcirc closed circle, shaded to the left
\bigcirc open circle, shaded to the right
question 3
solve the inequality
$1.23 + 1.6x < 2.83$

Explanation:

Step1: Isolate the x term

Subtract 10.2 from both sides:
$10.2 - x - 10.2 > 20.8 - 10.2$
$-x > 10.6$

Step2: Solve for x (reverse inequality)

Multiply both sides by -1, reverse inequality sign:
$x < -10.6$

Step3: Analyze graph rules

• Inequality is $<$: use open circle.
• $x <$ value: shade left of the point.

Answer:

open circle, shaded to the left
