P(1st B) = 1/8
P(2nd G) = 7/7
P(3rd B) = 0/6 = 0 (there is no more blue, so it's impossible)

P(1B AND 1G and 2ndB) = 0/336

What are the following of this function y = 4sin (2( x - <img src="https://tex.z-dn.net/?f=%5Cfrac%7B3%5Cpi%20%7D%7B4%7D" id="Te
Andrei [34K]

Answer:

See below...

Step-by-step explanation:

For a function whose formula is in this pattern:

y=A\sin\left(B(x-C)\right)

Amplitude: |A|

Period: \frac{2\pi}{B}

Phase Shift:  C

In this question, A=4,\,B=2,\,C=\frac{3\pi}{4}

Amplitude: 4

Period: \frac{2\pi}{2}=\pi

Phase Shift: \frac{3\pi}{4}

There is no vertical shift, so the midline is the x-axis whose equation is y = 0.

Also, because there is no vertical shift, the maximum is 4 and the minimum is -4.

The graph is attached.

Graph the linear function whose equation is y - 2 = - (x + 1)
DIA [1.3K]

Answer:

<h2>In the attachment</h2>

Step-by-step explanation:

Convert to the slope-intercept form (<em>y = mx + b</em>):

y - 2 = -(x + 1)              <em>use the distributive property</em>

y - 2 = -x - 1             <em>add 2 to both sides</em>

y - 2 + 2 = -x - 1 + 2

y = -x + 1

We only need two points to plot the graph of the linear function.

Select any two x values. Insert them into the equation.

Calculate the value of y.

For x = 1:

y = -1 + 1 = 0 → (1, 0)

For x = 0:

y = -0 + 1 = 1 → (0, 1)

Solve using the elimination method <br>x + 5y = 26 <br>- X+ 7y = 22​
S_A_V [24]

Answer:

x=6\\y=4

Step-by-step explanation:

Elimination method:

x+5y=26

-x+7y=22

Add these equations to eliminate x:

12y=48

Then solve 12y=48 for y:

12y=48

y=48/12

y=4

Write down an original equation:

x+5y=26

Substitute 4 for y in x+5y=26:

x+5(4)=26

x+20=26

x=26-20

x=6

{ x=6 and y=4 }    ⇒ (6,4)

<em />

<em>hope this helps...</em>
