Answer:
-3/4x
Step-by-step explanation:
Down 3, right 4. We know it's negative because it's declining, and going down till you reach the x-coordinate of the point gives us -3, and going right 4 units to the location of the point.

Answer:
The center of the tetrahedron divides each of the four heights (or medians) in the ratio 1:3 (in an equilateral triangle the corresponding ratio is 1:2). The smaller part is also the radius of the inscribed sphere. Therefore the radius of this sphere is one quarter of the height or 9 in your case.

- [Right Triangles Only] Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use PT to find the missing length.
<u>Step 2: Identify Variables</u>
Leg <em>a</em> = 9
Leg <em>b</em> = <em>x</em>
Hypotenuse <em>c</em> = 13
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitute [PT]: 9² + x² = 13²
- Isolate <em>x</em> term: x² = 13² - 9²
- Exponents: x² = 169 - 81
- Subtract: x² = 88
- Isolate <em>x</em>: x = 2√22
- Evaluate: x = 9.38083
- Round: x ≈ 9.4
