explanation :

8x + 7y + 4 - 6x + 15y + 16

then, equate denominator

8x - 6x +7y + 15y + 4 + 16

the answer is

2x + 22y + 20

hope this will help you

Answer:

2x + -8y + -20

Step-by-step explanation:

First solve the parenthisis.

(8x + 7y + 4) - 3(2x - 5y -8)

8x + 7y + 4 - 6x - 15y - 24

Now the like terms... combine 8x and -6, 7y and -15y, last but not least -24 and  4.

To end up with 2x -8y -20

Which system of linear inequalities Is represented by this graphed solution?
SashulF [63]

Answer:

y ≥ 3x - 1

y < -\frac{1}{2}x+2

Step-by-step explanation:

Let the equation of the solid line passing through (x', y') given in graph is,

y = mx + b

Here m = slope of the line

b = y-intercept

Slope of the solid line =

                                 m = \frac{3}{1}

                                 m = 3

y - intercept 'b' = -1

Therefore, equation of the line will be,

y = 3x - 1

Since, shaded (blue) area is above the line, inequality that will represent the solution area will be,

y ≥ 3x - 1

For the dotted line,

Slope of the line (m) = \frac{\text{Rise}}{\text{Run}}

                                  = \frac{-2}{4}

                                  = -\frac{1}{2}

y-intercept (b) = 2

Equation of the dotted line → y = -\frac{1}{2}x+2

Since, shaded (grey color) area is below the dotted line,

Inequality representing the solution area will be,

y < -\frac{1}{2}x+2

8 PTS.
Harman [31]

Answer:

The dependent variable:  the total cost

The independent variable: the amount of books


If the equation is  y = 8x + 200

y would be the dependent variable and x would be the independent variable


I hope this helps.
