Answer:

Step-by-step explanation:

\left( \dfrac{4}{5}x-5 \right) - \left(\dfrac{1}{3}x+4 \right) = \dfrac{4}{5}x-5-\dfrac{1}{3}x-4\\\\LCM \ of  \ 3 \ and \ 5  \ = \ 15\\\\=\dfrac{4*3}{5*3}x - \dfrac{1*5}{3*5}x -9\\\\\\=\dfrac{12}{15}x-\dfrac{5}{12}x-9\\\\=\dfrac{7}{15}x-9

Answer:

7/15x - 9

Step-by-step explanation:

(4/5x - 5) - (1/3x + 4)

remove the parentheses

4/5x - 5 - 1/3x - 4

simplify each variable

4/5x - 9 - 1/3x

7/15x - 9

1. What is an equation for the line with slope 2/3 and y-intercept 9?
Monica [59]
Question 1:

 The generic equation of the line is given by:
 y = mx + b

 Where,
 m: slope of the line
 b: cutting point with the y axis
 Substituting values ​​we have:
 y = \frac{2}3}x + 9

 Answer:
 an equation for the line with slope 2/3 and y-intercept is:
 y = \frac{2}3}x + 9

 Question 2:

 The standard equation of the line is given by:
 y-yo = m (x-xo)

 Where,
 m: slope of the line
 (xo, yo): ordered pair that belongs to the line
 The slope of the line is:
 m =  \frac{y2-y1}{x2-x1}
 Substituting values:
 m = \frac{1-(-3)}{3-1}
 m = \frac{1+3}{3-1}
 m = \frac{4}{2}
 m = 2

 We choose an ordered pair:
 (xo, yo) = (3, 1)

 Substituting values:
 y-1 = 2 (x-3)

 Rewriting:
 y = 2x - 6 + 1

y = 2x - 5
 Answer:
 An equation in slope-intercept form for the line that passes through the points (1, -3) and (3,1) is:
 y = 2x - 5


 Question 3:

 For this case, since the variation is direct, then we have an equation of the form:
 y = kx
 Where,
 k: constant of variation.
 We then have the following equation:
 -4y = 8x
 Rewriting we have:
 y = \frac{8}{-4}x

 y = -2x
 Therefore, the constate of variation is given by:
 k = -2

 Answer:
 the constant of variation is:
 k = -2

 Question 4:

 For this case, since the variation is direct, then we have an equation of the form:
 y = kx
 Where,
 k: constant of variation.
 We must find the constant k, for this we use the following data:
 y = 24 when x = 8
 Substituting values:
 24 = k8
 Clearing k we have:
 k =  \frac{24}{8} 

 k = 3

 Therefore, the equation is:
 y = 3x
 Thus, substituting x = 10 we have that the value of y is given by:
 y = 3 (10)

y = 30 Answer:
 the value of y when x = 10 is:
 y = 30

The manager’s likely error was forgetting to add the $2 back to the $18. Because $2 is roughly 11% of $18 for a markup you need to add the $2 back into the $18 for a total of $20.
