If you can answer this you get 20 points

Step-by-step explanation:

Left Side

If we let the price be represented by p and the quantity by q, then a suitable equation is ...

  p/30 +q/35 = 1 . . . . equation in intercept form

  7p +6q = 210 . . . . . multiply by 210

  p = -6/7q +30 . . . . solve for p

The slope is -6/7.

The "rate of change" is -6/7. (slope and "rate of change" mean the same)

The x-intercept is 35.

The number at the end is zero (35). (assuming "the end" is the right end of the graph)

The starting price is the y-intercept (30).

The rate of cost is the slope (-6/7).

Right Side

The cost starts at 20 and goes up 10 for each 5 games, so 2 per game. A suitable equation is ...

  y = 2x + 20

The rate of change is 2.

The x-intercept is where y=0. It will be -20/2 = -10.

The y-intercept is 20.

The graph has to do with games and cost, not minutes and feet. There is insufficient information to answer questions about minutes and feet.

Comment on these questions

The notations "per billions" on the left graph cause it to make no sense whatever. The ideas of "starting" and "ending" are usually time- or sequence-related. The graph shows nothing to indicate time or sequence. The idea of "rate of cost" for TV's is nonsensical. (Cost is a rate: dollars per unit.)

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
