Answer:

  • y -8 = 8/5(x +2)
  • y = 8/5x +56/5
  • 8x -5y = -56

Step-by-step explanation:

Since you're given a point and slope, it is convenient to start with that form.

<u>Point-slope form</u>

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

  y -8 = 8/5(x +2) . . . point-slope equation

__

<u>Slope-intercept form</u>

  y = mx + b . . . . . line with slope m and y-intercept b

The above equation can be rearranged to this form.

  y = 8/5x +16/5 +8

  y = 8/5x +56/5 . . . . . slope-intercept form

__

<u>Standard form</u>

  ax +by = c

Multiplying by 5 and subtracting the y-term gives the general form equation ...

  5y = 8x +56

  8x -5y +56 = 0

  8x -5y = -56 . . . . . . add -56 to put into standard form

$149 guitar; 29% discount​
Vikki [24]
Divide number of guitars by 100% and multiply into discount given



149/100 x 29

1.49 x 29

43.21



$43.21 had been removed

Therefore $105.79 is the guitar cost after discount

Ryan is trying a low-carbohydrate diet. He would like to keep the amount of carbs consumed in grams between the levels shown in
pentagon [3]

Compound inequality combines multiple single inequalities.

The solution and interpretation of the inequality is:

<em />x > 50<em> and </em>x < 150<em>.  Ryan needs to consume more than 50 grams of carbohydrates, but less than 150 grams of carbohydrates.</em>

<em />

We have:

110 < 2x + 10 and 2x + 10< 310

Solve for x in both inequalities

110 < 2x + 10

110 -10 < 2x

100 < 2x

Divide both sides by 2

50 < x

Rewrite as:

x > 50

Also, we have:

2x + 10< 310

2x< 310 - 10

2x< 300

Divide by 2

x < 150

So, the solutions to the inequalities are:

x > 50 and x < 150

This means that Ryan needs to consume more than 50 but less than 150 grams of carbohydrates.

Hence, (a) is correct

Show all work to identify the asymptotes and end behavior of the function f(x)= 5x/x-25.
jeyben [28]

Considering the given function and the asymptote concept, we have that:

  • The vertical asymptote is of x = 25.
  • The horizontal asymptote is of y = 5.
  • The end behavior is that as x \rightarrow \infty, f(x) \rightarrow 5.

<h3>What are the asymptotes of a function f(x)?</h3>

  • The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.
  • The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity. Hence it also gives the end behavior of the function.

In this problem, the function is:

f(x) = \frac{5x}{x - 25}.

The vertical asymptote is found as follows:

x - 25 = 0 -> x = 25.

The horizontal asymptote is found as follows:

y = \lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} \frac{5x}{x - 25} = \lim_{x \rightarrow \infty} \frac{5x}{x} = \lim_{x \rightarrow \infty} 5 = 5.

Hence the end behavior is that as x \rightarrow \infty, f(x) \rightarrow 5.
