The first choice,
... a. s(t) = ac[1 + μam cos (2πfmt)] cos (2πfct)
has the carrier frequency cos(2πfct) amplitude modulated by the message signal.
The other expressions represent frequency and phase modulation of various kinds.
Answer:
One solution.
Step-by-step explanation:
Step 1: Write equation
5(x + 2) - 3 = 3x - 8x + 7
Step 2: Solve for <em>x</em>
<u>Distribute 5:</u> 5x + 10 - 3 = 3x - 8x + 7
<u>Combine like terms:</u> 5x + 7 = -5x + 7
<u>Add 5x to both sides:</u> 10x + 7 = 7
<u>Subtract 7 on both sides:</u> 10x = 0
<u>Divide both sides by 10:</u> x = 0
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
5(0 + 2) - 3 = 3(0) - 8(0) + 7
5(2) - 3 = 7
10 - 3 = 7
7 = 7
all angles add up to 180, so add like terms and solve for x. plug x into C to find the angle C measure.
