Find the energies of the signals illustrated in fig p1.1-1. comment on the effect on energy of sign change, time shifting, or doubling of the signal. what is the effect on the energy if the signal is muliplied by k? all figures are square wave with different magnitudes

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

-9

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

answer is b
