Question

PLEASE HALP IM TIMED!!! WILL GIVE 25 PTS

Vera claimed the solution set on the number line represents the inequality Negative 78.9999 greater-than-or-equal-to x.

A number line going from negative 83 to negative 77. A closed circle is at negative 79. Everything to the left of the circle is shaded.

Which error did Vera make?
Vera wrote the inequality with the variable on the left side of the relation symbol.
Vera wrote a relation symbol that does not represent the direction of the ray.
Vera selected an inequality that does not include –79 in its solution set.
Vera used the wrong number in her inequality.

Answer 1

So basically, we have [-83, -77] as the whole thing.
There's a circle that limits [-83, -79) as a shaded zone.

Vera claims that -78.9999
`\geq` X, which is false.
Vera wrote a relation symbol that doesn't represent the ray's direction. She went the other way around.
