Answer:

x = 8/13

Step-by-step explanation:

6 - 3x - 3/5(15x + 20) = 7(2x/7 - 2) - x

6 - 3x - 9x - 12 = 2x - 14 - x

6 - 12 + 14 = 2x - x + 3x + 9x

8 = 13x

x = 8/13

Which graph represents the function y = cos(4x)?<br><br> Answer is graph B
VARVARA [1.3K]

Answer:

Step-by-step explanation:

Let the equation of the cosine function is,

y = Acos(Bx)

From the graph attached,

A = Amplitude = \frac{1-(-1)}{2}

   = 1

B = \frac{2\pi}{\text{Period}}

B = \frac{2\pi}{\frac{\pi}{2}-0}

B = \frac{4\pi}{\pi}

B = 4

Therefore, equation of the cosine wave given in the graph will be,

y = 1.Cos(4x)

y = Cos(4x)
