## Solution to QOTD 3/30/2020

A solution to a system of equations is the number (or numbers) that make the equations true simultaneously. Or, looking at the graph, it is the location where the lines and or curves intersect.

For this particular graph, the line crosses the parabola at the points (4, 10) and (7, 7.75), so the solution was C.

## Solution to QOTD 3/26/2020

For this question, you will have to apply the some properties of angles and arcs in circles. Here are a few of those that will help:

1. The measure of an inscribed angle is 1/2 the measure of its intercepted arc;
2. The measure of a central angle is equal to the measure of its intercepted arc;
3. When an inscribed angle intercepts a diameter, the angle will be a right angle.

First, because we are given that <A is 30*, we know that the measure of Arc BD is 60*. (see property #1 above.) Therefore, the measure of <BCD is also 60*. (see property #2)

Next, <ABD intercepts the diameter of the circle, so, from property #3, <ABD is 90*.

## Solution to QOTD 3/25/2020

A. Jo is correct. When multiplying the same bases (in this case the variable x is the base) with different exponents, the exponents get added together.

The key here is to make sure that you are understanding the fundamentals of exponents, and also how to work with fractions.
