Answer: First Option

No solution

Step-by-step explanation:

We have the following system of linear equations

y = -2x + 1

4x + 2y = -2

-------------------------------------

To solve the system of equations using the substitution method, enter the first equation in the second equation as shown below.

4x + 2(-2x + 1) = -2

4x -4x + 2 = -2

0= -4

The variable x is eliminated and 0 is not equal to -4. So the system has no solution

Answer:

No solution

Step-by-step explanation:

The first equation is y=-2x+1

The second equation is 4x+2y=-2.

Put the first equation into the second one.

4x+2(-2x+1)=-2.

4x-4x+2=-2.

4x-4x=-2-2.

0=-4.

This is not TRUE.

Therefore the system has no solution

An analog signal with a bandwidth of 36MHz is sampled at a frequency (fs) of 36,000,000 samples per second during the ADC (analo
Elza [17]

Answer:

The signal would have experienced aliasing.

Step-by-step explanation:

Given that:

the bandwidth of the signal f_m = 36MHz

= 36 × 10⁶ Hz

The sampling frequency f_s = 36 × 10⁶ Hz

Suppose the sampling frequency is equivalent to the bandwidth of the signal, then aliasing will occur.

Therefore, according to the Nyquist criteria;

Nyquist criteria posit that if the sampling frequency is more above twice the maximum frequency to be sampled, a repeating waveform can be accurately reconstructed.

∴

By Nyquist criteria, for perfect reconstruction of an original signal, i.e. the received signal without aliasing effect;

Then,

f_s \geq 2f_m

∴

The signal would have experienced aliasing.

How do you use a number line to solve 235+123
Novosadov [1.4K]
<span>Number line refers to a mathematical process of solving the equation with the use of lines.
=> 235 + 123
Starting from 0 you count 1 up to 235. Then starting from 235 you additionally count another 123.
Then from zero start counting the total number to the line you stopped when adding 123 to 235.

This simply equals to
=> 235 + 123
=> 358.
Pls. see attached image for illustration of number line.</span>Answer here
