Answer: C) Changing one or more properties of a sine wave in response to data.

Step-by-step explanation:

Modulation is primarily used in telecommunications sector. It the process by which data is transmitted via electrical signals. It is the process of imposing an input signal on to a wave carrier. It is the pillar of data communication that enables the use information carriers of signals that are electrical and optical. Altering the carrier/ periodic waveform results in Modulation. The amplitude frequency and phase are conveyed. There are different types of Modulation which includes: amplitude Modulation, frequency Modulation, and phase Modulation.

What is the solution of the system of equations . 4x-5y=-17 , x+6y=61
PSYCHO15rus [73]

To solve this system, we can use substitution.


x + 6y = 61

x = 61 - 6y


Now we substitute into the other equation.


4 (61 - 6y) - 5y = -17

244 - 24y - 5y = -17

244 -29y = -17

29y = 261

y = 9


Now we find x.


x + 6 (9) = 61

x + 54 = 61

x = 7


That means the solution to this system is (7, 9)

Write the slope-intercept form of the equation of the line with the given characteristics. Perpendicular to y = -5x + 2 and pass
natka813 [3]

The slope intercept form of a line can be expressed as,

y=mx+c

Here, m is the slope of the line and c is the y intercept.

Comparing the above equation with the given equation of a line y=-5x+2, we get

m=-5.

The slope of a line perpendicular to line with slope m is -1/m.

Hence, the slope of line perpendicular to y=-5x+2 is,

m_1=\frac{-1}{m}=\frac{-1}{-5}=\frac{1}{5}

The new line is given to be passing through point with coordinates (x1, y1)=(3, -1).

The point slope form of a line passing through point with coordinates (x1, y1)=(3, -1) and having slope m1 is,

\begin{gathered} y-y_1=m_1(x-x_1) \\ y-(-1)=\frac{1}{5}(x-3) \\ y+1=\frac{1}{5}x-\frac{3}{5} \\ y=\frac{1}{5}x-\frac{3}{5}-1 \\ y=\frac{1}{5}x-\frac{3-5}{5} \\ y=\frac{1}{5}x-\frac{8}{5} \end{gathered}

Therefore, the slope-intercept form of the equation of the line perpendicular to y = -5x + 2 and passing through (3,-1) is,

y=\frac{1}{5}x-\frac{8}{5}

Does this graph represent a function? why or why not?
AVprozaik [17]

Answer:

D. Yes, because it passes the vertical line test

Step-by-step explanation:

the vertical line test is a test you do by drawing a vertical line through the graph of the function if more than one point from the function lies on the line it does not represent a function

in this graph at any part if you draw a vertical line it passes through one point only
