Answer:

Books'R'Us is proportional. Bargains'R'Us is not proportional.

Step-by-step explanation:

Susan buys books at two stores. At Books'R'Us, she can buy a book for $1.25 each. At Bargains'R'Us, she made a deal to buy a set of 3 books for $4.00 and a set of 5 books for $5.00.

Book'R'Us is proportional because each book costs a consistent value of $1.25. 0 books is $0. 1 book will be $1.25 and 2 books will be $2.50 and 3 books will be $3.75.

Bargains'R'Us is not proportional because each book has a different price depending on the bargain. Though 0 books is $0, a set of 3 costs $4.00 or $1.34 a book. A set of 5 costs $5.00 or $1 per book. The cost is not consistent or constant. It changes from situation to situation. This is not proportional.

Identify an equation in slope intercept form for the line parallel to y= -2/3x+8 that passes through (4, -5)
Evgen [1.6K]

Answer:

3y = -2x -7

Step-by-step explanation:

The equation of the line;

     y = -\frac{2}{3}x + 8

Unknown:

Equation of the line passing through (4, -5);

Solution:

To solve this problem;

    the equation of a line is given as;

        y = mx + c

where x and y are the coordinate

           m is the slope

          c is the intercept

To solve this problem,

  The slope  -\frac{2}{3} if the same as that of the new line since they are parallel;

Equation of the new line;

    x  = 4 and y = -5

     -5 =  -\frac{2}{3} x 4 + c

      -5 = -\frac{8}{3} + c

       c  = -5 + \frac{8}{3}

       c = -\frac{7}{3}

So, the equation of the line is;

    y =  -\frac{2}{3}x - \frac{7}{3}

 or ;

     3y = -2x -7

The Blinking Rockets baseball team has had 127,034 visitors to their fan website. Rounded to the nearest ten thousand how many v
horsena [70]

Answer:

Visitors = 130000

Step-by-step explanation:

Given

Visitors = 127034

Required

Approximate to the nearest ten thousand

First, identify the digit at the ten thousand position

From the given numbers of visitors, the digit is 2.

So, the next digit (which is 7) will be approximated and added to 2.

7 > 5. So, 1 will be added to 2.

The number of visitors becomes:

Visitors = 130000
