Answer:
Combine like terms in the left side. Substract both sides. Divide by both sides therefore. the answer is the option
Step-by-step explanation:
You would subtract 3x from the left side, and get -2 = -2x, so x=1 would be your answer
5t + (t - 3) - [(7t + 5) - (8 - 3t)] (multiply -1 to (8 - 3t)
5t + (t - 3) - [(7t + 5) - 8 + 3t]
5t + (t - 3) - [7t + 3t + 5 - 8]
5t + (t - 3) - [10t - 3] (multiply -1 to [10t - 3]
5t + (t - 3) - 10t + 3
5t + t - 10t - 3 + 3
-4t
answer
Answer:
The amplitude is 4
Step-by-step explanation:
Recall that the amplitude of a harmonic form like this one based on the cosine function is the absolute value of the coefficient that multiplies the function. In our case that coefficient is 4.
So the amplitude of this function is "4".
