2/3 (x - 7 ) = -2<br> AL y = 5/3 B: 8 1/3 C: 10 D: 4

nika2105 [10]

Answer:

D: 4

Step-by-step explanation:

1. Solve the equation

$\begin{array}{rcl}\dfrac{2}{3}(x - 7) & = & -2\\\\2(x - 7) & = & -6\\x - 7 & = & -3\\x & = & \mathbf{4}\\\end{array}$

2. Check

$\begin{array}{rcl}\dfrac{2}{3}(4 - 7) & = & -2\\\\\dfrac{2}{3}(-3) & = & -2\\\\-2 & = & -2\\\end{array}$

Find the values of x and y that satisfy the equation.<br><br> 3x+6i=27+yi<br> x

Misha Larkins [42]

Answer:

x = 9

y = 6

Step-by-step explanation:

3x+6i=27+yi

The real components have to be equal and the imaginary components have to be equal

3x = 27

divide by 3

3x/3 = 27/3

x=9

6i = yi

Divide by i

6 = y

Answer:

$y=2\sin(x)-1$

Step-by-step explanation:

Let's break it down:

In the sinusoidal function $y=a\sin b(x-c)+d$ :

$a$ represents Amplitude
$b$ represents a constant related to the Period
$c$ represents Phase Shift
$d$ represents Vertical Shift

To find Amplitude, divide the entire height of the function (from top to bottom) by two, or find the vertical distance between the horizontal line of symmetry and the highest/lowest point of the wave. In this case, Amplitude is 2.

To find $b$ , use $T=\frac{2\pi}{b}$ , where $T$ is the period of the function. To find the period, count the horizontal distance of the length of one complete cycle. In this case, period is $2\pi$ and therefore
