Answer:

  in bold below

Step-by-step explanation:

<u>Left Side</u>

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).

__

<u>Right Side</u>

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.

_____

<em>Comment on these questions</em>

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 <em>is</em> a rate: dollars per unit.)

Combine like terms.<br><br> y + 3 + 9(y + 5) =
Mnenie [13.5K]

Answer:

The answer is 10y + 48.

Step-by-step explanation:

First you have to get rid of brackets by expanding :

y + 3 + 9(y + 5) \\  = y + 3 + 9y + 45

Next you have to collect like-terms :

y + 3 + 9y + 45 \\  = 10y + 48

Find the coordinates of the midpoint of the segment whose endpoints are H(10, 1) and K(4, 7).
Oliga [24]

The formula of a midpoint of a segment AB:

A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\M_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)

We have:

H(10; 1); K(4; 7)

substitute:

M_{HK}\left(\dfrac{10+4}{2};\ \dfrac{1+7}{2}\right)\to M_{HK}\left(\dfrac{14}{2};\ \dfrac{8}{2}\right)\to M_{HK}(7;\ 4)

Answer: (7, 4)

Choose the function whose graph is given by:
katen-ka-za [31]

Answer:

D. y=\tan (x-\pi)+2

Step-by-step explanation:

We are given the graph of the transformed tangent function.

As, we can see that the graph is shifted 2 units upwards.

That is, the parent function is translated 2 units up.

So, the new function will be of the form, y=\tan (x)+2.

Thus, options A and C are not correct.

Moreover, 'If a function f(x) has period P, then the function cf(bx) will have period \frac{P}{|b|}.

Also, form the figure, we see that the period of the graphed function is \pi.

Since, y=\tan (x) have period \pi.

So, function in option B will have period \frac{\pi}{2}, which is not possible.

<em>Further, function in option D have period \pi.</em>

Thus, the equation of the graphed function is, y=\tan (x-\pi)+2.
