9514 1404 393

Answer:

  r = 1

Step-by-step explanation:

Solving the equation for r gives ...

  r = y/x

Using the first line of the table, we find r to be ...

  r = 5.8/5.8 = 1

The constant of proportionality is r = 1.

Tcecarenko [31]
20 weeks.

Bar graph: Start with zero, and the next ones (bars) will all increase by a 15 interval over the period of 20 weeks. So 1 bar per week, and there are 20 weeks, with each bar having a 15$ profit difference. Sorry, can't draw it here.

equation: 15x=300
                15/(15x=300)/15
                 x=20

Using translation concepts, the equation of g(x) is given as follows:

g(x) = -\frac{35}{x + 10} - 1

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

For this problem, the parent function is given by:

f(x) = \frac{1}{x}

For a horizontal compression by a factor of 1/5, we have to find f(1/5x), hence:

g(x) = \frac{1}{\frac{1}{5}}x = \frac{5}{x}

For a vertical stretch by a factor of 7, we have to multiply by 7, hence:

g(x) = \frac{35}{x}

For a reflection in the y-axis, we have to find g(-x), hence:

g(x) = \frac{35}{-x} = -\frac{35}{x}

For a translation of 10 units left, we have to find g(x + 10), hence:

g(x) = -\frac{35}{x + 10}

For a translation of 1 unit down, we have to subtract one, hence:

g(x) = -\frac{35}{x + 10} - 1
