<h3>Answer:  Choice B</h3>

Explanation:

The blue shaded region describes any x value that is smaller than -3, or that is equal to -3. We can phrase it as "x is less than or equal to -3". Therefore, that's why we go for x \le -3

If you graphed x < -3, without the "or equal to" portion, then you would have an open circle at the endpoint. The open circle means we don't include that value as part of the solution set.

Answer:

66

Step-by-step explanation:

Angle 2 and 4 are supplementary, so if angle 4 is 123, then 180-123=57.

So angle 2 is 57.

Then, if angle 2 and 3 are 57 and we know that all angles of a triangle have to add up to 180, then:

                             57+57+angle 1=180

                                114+ angle 1=180

                                        angle 1= 66

netineya [11]

Answer:

An interest-bearing account paying a stated nominal or annual interest rate of 3.880% compounded monthly, would translate to an Annual Percentage Yield (APY) or Effective Annual Rate (EAR) of 3.95%. This means that $100.00 will grow to $103.95 ($103.95 rounded) after one year.
