Answer:

A: 50 + 30h ≤ 280

B: 50 + 30h ≤ 280

-50 - 50

30 ÷ 30h ≤ 230 ÷ 30

h ≤ 7.66 repeating or about 8.

Solve for x -2x - 5 + 4x = 7 + 6x Question 2 options: x=3 x=2 x= -3 x= -2

noname [10]

Answer:

x=-4

Step-by-step explanation:

x - 2x - 5 +4x = 7 + 6x

3x - 5 = 7 +6x

-3x -3x

-5 = 7 + 3x

-7 -7

-12 = 3x

-12/3= 3x/3

-4 = x

Does anyone know how to graph trigonometric functions for algebra 2?

anastassius [24]

Solution:

Give the following below

$\begin{gathered} amplitude=3 \\ period=\frac{\pi}{2} \\ midline,\text{ }y=-1 \\ Passing\text{ through the point }(0,2) \end{gathered}$

To find the cosine function, we will apply the general formula for cosine function below

$\begin{gathered} f(x)=a\cos(bx-c)+d \\ Where \\ a\text{ is the amplitude} \\ b\text{ represents the speed of the cycle} \\ d\text{ is the vertical shift} \\ \frac{c}{b}\text{ is the phase shift \lparen horizontal shift\rparen} \\ Period=\frac{2\pi}{b} \end{gathered}$

To find the value of b

$\begin{gathered} Period=\frac{\pi}{2} \\ \frac{2\pi}{b}=\frac{\pi}{2} \\ Crossmultiply \\ b\times\pi=2\times2\pi \\ b=\frac{4\pi}{\pi} \\ b=4 \end{gathered}$ $\begin{gathered} a=3 \\ b=4 \\ d=-1 \\ c=0 \end{gathered}$

Substitute the values of the variables into the general formula for cosine function

$\begin{gathered} f(x)=a\cos(bx-c)+d \\ f(x)=3\cos(4x-0)-1 \\ f(x)=3\cos4x-1 \end{gathered}$

Applying a graphing tool,

The graph of one cycle of the function is shown below
