Question

Mariya was asked to solve StartFraction a over negative 13 EndFraction less-than-or-equal-to negative 16 and then graph the solution. Her work is shown below. Step Mariya’s work StartFraction a over negative 13 EndFraction less-than-or-equal-to negative 16 Step 1 (Negative 13) StartFraction a over negative 13 EndFraction less-than-or-equal-to negative 16 (negative 13) Step 2 a greater-than-or-equal-to 208 Step 3 A number line going from 205 to 211. An open circle is at 208. Everything to the right of the circle is shaded. In which step, if any, did Mariya make a mistake in her work? Step 1 Step 2 Step 3 No mistake found

Answer 1

Answer:

the answer is step 3 because the circle on the number line is open.

pls make mine as the  Brainliest answer that would really help

Answer 2

Mariya's mistake in solving the inequality and plotting the number line is in step 3

How to determine the mistake in the step?

The inequality is given as:

$\frac{a}{-13} \le -16$

Multiply both sides of the inequality by -13

$a \ge 208$

The above means that the solution to the inequality are numbers greater than or equal to 208.

This means that we make use of a closed circle

In step 3 of Mariya's solution, the number line uses an open circle

Hence, Mariya's mistake is in step 3
