41. find all solutions to the following equations. remember to check for extraneous solutions.
1. log2(3x + 7) = 4

Ans.

X=3

Step-by-step explanation:

Ok, there are several ways to solve this, I chose the one that can be more visual friendly to you.

SInce the log are based 2, we are going to be using this base on both sides of the equation, so, let Y = (3X+7).

This means.

Since Y = (3X+7)

Therefore X=3

Best of luck.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
