A. This is a what YOU think... how do YOU see it. to me, it looks like it lays down on its left side ... it spun to the left or rotated 90 degrees to the left (of course it could have rotated 270 degrees to the right)
B. Good job
C. Look at your answers in part B. (Ignore the third one until you think you have it. ). What happens? X goes to y and y goes to x? So the rule is (x,y) —> ( y, x)? No. The y changes signs... so ( -y, x)
D. What we just said in words in part C: the x & y switch places and the y changes signs. More “math-ey” sounding: the variables reverse and the y is multiplied by -1

Order the ratios from least to greatest 6:3 13 to 4 19/2 15 to 10 8:2

Alik [6]

6:3 = 6/3 = 2

13 to 4 = 13:4 = 13/4 = 3.25

19/2 = 9.5

15 to 10 = 15:10 = 15/10 = 1.5

8:2 = 8/2 = 4

From the least to the greatest:

15 to 10 , 6:3, 13 to 4, 19/2

I hope this explains it.

Polynomials are algebraic expressions represented by variables and coefficients.

<h3>(a) How to determine the interval the open seats increased</h3>

This is the interval, where the open seats increase the same time the time in minutes increases.

From the graph, the open seats increases at the interval (100, 600)

<h3>(b) The time the first meeting ended</h3>

This is the first point where the curve changes its direction from decreasing values to increasing values

From the graph, the curve changes its direction at point (25,100)

Hence, the first meeting ended at 10:25 AM

<h3>(c) When there were 700 open seats</h3>

From the graph, we have:

(x,y) = (5, 700)

Hence, there were 700 open seats at 10:05 AM

<h3>(d) The average rate of change from 10:00 AM to 10:25 AM</h3>

At 10:00 AM, we have:

(x,y) = (0,800)

At 10:25 AM, we have:

(x,y) = (25,100)

So, the average rate of change is:

$m = \frac{y_2 -y_1}{x_2 -x_1}$

This gives

$m = \frac{100 - 800}{25 - 0}$

$m = \frac{-700}{25 }$

$m = -28$

Hence, the average rate of change from 10:00 AM to 10:25 AM is -28 people per minute
