Need help im confused 15 points

Hi, the answers are actually simple. Please refer below for correct answers:-

1. 100 feet above sea level.

2. A debit of $13

3. 46°F above zero

4. A credit of $17.

How to find it?

There is exactly no real equation to find it but we use our own logic and common sense.

Let's take, for example, Question 1. In it, we can make it's opposite by converting the auxillary functional word. I meant that, we can convert the word "below" to "above" , so , we made it's opposite or negative expression. Likewise, for all other equations and sentences, we can do the same.

But first of all, you must know the opposite of certain words like credit, debit etc. Then, this will become very simple.

Hope it helps you and made you understand

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
