### Subject: Communication

Describe the process of the linear model of communication? What does this model of communication not include?

The linear model of communication is a one-way model. This model begins with a sender who encodes a message and transmits it through a channel, the source the message is sent through. The message is received by a receiver, the target of the original sender, which is the destination. sender -->[channel]-->receiver This model does not include any type of feedback or response. A good example of this type of communication is a radio broadcast, when there is no number to call in and provide feedback.

### Subject: Algebra

Solve the following equation algebraically, and check using substitution: 4+3(x+2)=12−5x

Simplify both sides, and then isolate the variables: 4+3(x+2)=12−5x 4+3x+6=12-5x 10+3x=12-5x 10+3x+5x=12 10+8x=12 8x=12-10 8x=2 x=2/8 x=1/4 Substitute the value found for x to check your answer: 4+3( (1/4) + 2) = 12-5(1/4) 4+(3/4)+6=12-(5/4) 10 3/4 = 10 3/4
