Answer:
supplementary, 65 degrees
Step-by-step explanation:
According to the question statement, the total sum of students is 221, which includes the students that ride on bus and the students that ride in a van.
The students that ride in a van are five, the students that ride on bus are 6 times s which is the product of the number of buses and the number of students that are on each bus.
Write all this information into an equation, this way:

Now, solve the equation for s to find the number of students that are on each bus.

There are 36 students on each bus.
1) Solve the first inequality
3y ≤ 2x + 6
=> y ≤ 2x/3 + 2
2) Draw the line y = 2x/3 + 2
3) Shade the region below the line y = 2x/3 + 2
4) Solve the inequality 2x + y > 0
=> y > - 2x
5) draw the line y = -2x
6) Shade the region above the line y = -2x
7) The solution is the region between the two lines shaded including the portion of the line y = 2x/3 + 2
Answer:
See answer below
Step-by-step explanation:
Hi there,
To get started, recall the average rate of change formula (essentially the same thing as slope):

So, just determine the average rate for each function between points [0,2] (a and b for the formula above, respectively).
To make it less time consuming, you do not need to do the division portion as it is same for all of them and (2-0) is greater than 1:

Without even doing the divison of (b-a), we can already see that the function with smallest average rate of change between [0,2] is f(x).
thanks,
Answer:
322.28
A
Step-by-step explanation:
Area of the rectangle
L = 30
W = 21
Area = 30 * 21
Area = 630
Area of the circles
Radius = 7 m
Area = pi r^2
Area = 3.14 * 7^2
Area = 153.86 m^2
Area of both circles = 307.72
Area of the Shaded Region
Area of shaded region = area of the rectangle - area of 2 circles.
Area of Shaded Region = 630 - 307.72
Area of Shaded Region = 322.28
