See attachment for the graph of the inequality expression x + 2y > 6

<h3>How to graph the conditions?</h3>

The condition is given as:

{(x, y): x + 2y > 6}

This means that

x + 2y > 6

The above is an inequality expression, where the variables are x and y

So, we simply plot the graph of the inequality expression x + 2y > 6

Rewrite the equation so that it does not have fractions 2- 5/6x = 7/8

sashaice [31]

the common denominator of 5/6 and 7/8 is 24, so multiply both sides of the equation (every term) by 24:

24(5/6)x + 24(2) = 24(7/8)

the denominators will cancel out so you have:

4(5x) + 48 = 3(7)

do the multiplication:

20x + 48 = 21

fractions have been eliminated, and if you want to continue to solve:

20x = -27

x = -27/20

a sinusoid always function has an amplitude of 3, a frequency of 1/8pi, and a midline at 2. Which of the following equations sat

Katen [24]

Answer:

The correct option is;

f(x) = 3·sin x/8·π + 2

Step-by-step explanation:

The given parameters for the sinusoidal function are;

Amplitude of oscillation = 3

Frequency of oscillation = 1/8·π

Midline of oscillation= 2

The general form of sinusoidal equation is y = A·sin(B(x - C)) + D

Where;

A = The amplitude

B = The frequency

C = The horizontal shift

D = The midline or vertical shift

Substituting the given values into the general form of sinusoidal equation, we have;

f(x) = y = 3·sin(1/8·π(x - 0)) + 2 = 3·sin(x/8·π) + 2

Which gives;

f(x) = 3·sin(x/8·π) + 2.

Solve the following inequality for w then simplify <br> -w+9>6w+8

Alla [95]

Answer:

$\displaystyle (-\infty,\frac{1}{7})$

Step-by-step explanation:

<u>Inequalities</u>

To solve the inequality:

$-w+9>6w+8$

We need to perform the required operations on both sides of the inequality to have the variable w isolated.

First, we subtract 9:

$-w+9>6w+8$

$-w>6w+8-9$

Subtracting 6w:

$-w-6w>+8-9$

Operating:

-7w>-1

Now we divide by -7 but recall that when dividing by a negative number, we must flip the inequality sign:

$\displaystyle w$

Operating:

$\displaystyle w$

Solution:

$\mathbf{\displaystyle (-\infty,\frac{1}{7})}$
