Write an equation of the line that passes through (2 , 0) and is perpendicular to the line y=-1/7x-3

Mathematics

Answer:

y = 7x - 14

Step-by-step explanation:

If the given line has slope -1/7, then any perpendicular line has the slope which is the negative reciprocal of -1/7.  That is +7.

Apply the slope-intercept formula for the equation of a straight line, using 0 for y, 2 for x and searching for the y-intercept value b:

0 = 7(2) + b.  Then b = -14, and the desired equation is y = 7x - 14.

Our equation is:

(x/-4)+11=5; we need to get x by itself in order to solve. Let's subtract 11 from both sides. (x/-4)=-6; let's now multiply both sides by -4. x=24; let's check to see if x is 24 by plugging it in.

24/-4=-6+11=5

So, x=24.

Use the Pythagorean theorem to find the missing side of the right triangle a=7.5, b=12.3 c=?
Schach [20]

Answer:

14.41

Step-by-step explanation:

Pythagorean Theorem: a² + b²  = c²

a=7.5 b=12.3 c=❒

7.5² + 12.3² = 56.25 + 151.29 = 207.54

√207.54 is approximately 14.41

Hope this helps,
