2x - 3(x - 4) = 11
2x - 3x + 12 = 11
-1x = -1, x = 1
y = 1 - 4 = -3, y = -3
Solution: x = 1, y = -3

Drag the labels to the correct locations on the table. Not all labels will be used.

For f(x) = cos(x) we have:

  • midline = 0
  • amplitude = 1
  • period = 2π
  • graph = bottom graph on the second image.

<h3>What are the midline, amplitude, period, and graph of the function f(x)=cos(x)?</h3>

For a general cosine function, we have:

f(x) = A*cos(kx + p) + M

Where:

  • A is the amplitude.
  • k is the frequency.
  • p is the phase.
  • M is the midline.

For the function:

f(x) = cos(x).

We can see that:

A = 1, M = 0, k = 1, p = 0.

So, the amplitude is equal to 1, and the midline is equal to zero.

Now we also need to get the period. By definition of the trigonometric functions sin(x) and cos(x), we know that the period of the two is equal to 2π.

Finally, we need to identify the graph of cos(x).

Notice that:

f(0) = cos(0) = 1.

So the graph of f(x) = cos(x) is the graph with an y-intercept equal to 1. Which is the bottom graph on the second image.

Make the variable in the brackets as the subject of each of the following formulae mx + 2x = 6​
Airida [17]

Answer:

See Explanation

Step-by-step explanation:

Given

mx + 2x = 6

Required

Make the variable in bracket the subject

From the given expression, none of the variables (m and x) are in brackets.

So, I will solve for m and then solve for x

Solving for m:

mx + 2x = 6

Subtract 2x from both sides

mx = 6 - 2x

Divide both sides by x

m = \frac{6 - 2x}{x}

Solving for x:

mx + 2x = 6

Factorize

x(m+2)= 6

Divide both sides by m + 2

x = \frac{6}{m+2}
