Answer:C would be the correct answer
Step-by-step explanation:
Answer:
(D)5
Step-by-step explanation:
Given a line:
Comparing with the slope-intercept form y=mx+c
Slope, m
Definition: Two lines are perpendicular if the product of their slopes equals -1.
Therefore, the slope of a line perpendicular to the given line
Therefore, a line that is perpendicular and passes through the point (3,1) is:
Comparing with the slope-intercept from: y=mx+c
The y-intercept of the perpendicular line is therefore 5.
The correct option is D.

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
a = <em>b</em>
b = 14
c = 23
<u>Step 2: Find </u><em><u>b</u></em>
- Substitute [PT]: b² + 14² = 23²
- Isolate <em>b </em>term: b² = 23² - 14²
- Exponents: b² = 529 - 196
- Subtract: b² = 333
- Isolate <em>b</em>: b = 3√37
