Which system of equations could be graphed to solve the equation below?

Taya2010 [7]

Answer:

$\left\{\begin{array}{l}y_1=\log (2x+1)\\ \\y_2=3x-2\end{array}\right.$

Step-by-step explanation:

Given the equation

$\log (2x+1)=3x-2$

This equation consists of two parts. In the left part, there is a logarithmic function $y=log (2x+1)$

In the right part, there is a linear function $y=3x-2$

To solve the equation graphically, you have to plot the graphs of these two functions and find the point of intersection of these graphs.

Hence, appropriate system is

$\left\{\begin{array}{l}y_1=\log (2x+1)\\ \\y_2=3x-2\end{array}\right.$

The question is asking how many combinations of two people can be made from a group of ten people.

Using the formula C(10,2) = 10!/(2! x (10 - 2)! = 10!/(2! x 8!) = 45 handshakes.

A simple way to prove this is each person shakes the hand of 9 other people
10 x 9 = 90 but this counts every handshake from the view of both people involved.
The actual number of handshakes is therefore 90 / 2 = 45
