42. b?

Answer 10

42. First off, the sign cannot have an "or equal to" affiliated with it since the graph shows a dashed line. Dashed lines mean that the inequality cannot have an "equal to affiliated it." You were close but the answer would be A.

44. According to your answer, the area of the triangle would have turned out to be 1.5 inches squared. Not sure how you came up with this answer, but my strategy was just to subtract 1 then divide by 2 for each answer choice. I then multiplied the number gotten from dividing by the answer choice, then multiplying by 1/2. I got 9 inches for my answer because:

9 - 1 = 8
8 / 2 = 4 (height)
Base: 9 inches
Height: 4 inches

9 * 4 * .5 = 18 inches squared

Answer 11

And if you don't know, the line under the inequality sign means, "or equal to"

Answer 12

oh okat

Answer 13

what about 47?

Answer 14

Think of this problem as an algebra question except with 3 different sides. In a normal algebra equation we have the terms on the left side and the terms on the right side. In an inequality such as this one, we have a left, middle, and right.

Since the variable is in the middle, we will focus on attempting to isolate the 'x' in the middle. The picture shows:
\[-9 \le 2x + 1 < 5\]
The first step would be to subtract 1 from all 3 sides. This would give us:
\[-10 \le 2x < 4\]
Now the last step is just to divide by 2 from all 3 sides in order to isolate the variable.
\[\frac{ -10 \le 2x < 4 }{ 2 } = -5 \le x < 2\]
This would be the answer. You can check this by plugging in the term, '-5' since it is the only term that is exclusive to the answer choice.
\[-9 \le 2(-5) + 1 < 5 = -9 \le -9 < 5\]
