============================================================
Explanation:
The inequality 6x - 10y ≥ 9 solves to y ≤ (3/5)x - 9/10 when you isolate y.
Graph the line y = (3/5)x - 9/10 and make this a solid line. The boundary line is solid due to the "or equal to" as part of the inequality sign. We shade below the boundary line because of the "less than" after we isolated for y.
Now graph all of the points given as I've done so in the diagram below. The points in the blue shaded region, or on the boundary line, are part of the solution set. Those points are D, E and F.
We can verify this algebraically. For instance, if we weren't sure point E was a solution or not, we would plug the coordinates into the inequality to get...
6x - 10y ≥ 9
6(5) - 10(2) ≥ 9 .... plug in (x,y) = (5,2)
30 - 20 ≥ 9
10 ≥ 9 ... this is a true statement
Since we end up with a true statement, this verifies point E is one of the solutions. I'll let you check points D and F.
-----------
I'll show an example of something that doesn't work. Let's pick on point A.
We'll plug in (x,y) = (-1,1)
6x - 10y ≥ 9
6(-1) - 10(1) ≥ 9
-6 - 10 ≥ 9
-16 ≥ 9
The last inequality is false because -16 is smaller than 9. So this shows point A is not a solution. Choices B and C are non-solutions for similar reasons.

200 students attend Ridgewood Junior High School. 25% of students bring their lunch to school everyday. How many students brought their lunch to school on Thursday?
Answers
sorry est un site Web Internet spécialement conçue 4
25% of 100 is 25 and 200 is twice as much as 100. So then double the 25 to 50.
You can also set up a proportion of 25%/100% = ?/200 and cross multiply and divide.
Another way is to manipulate the numbers. Instead of 25% of 200 you can say 200% of 25. 200% is the same as saying twice as much as the number so what is twice the number 25? 50!

Answer:
Perimeter of the given figure = 28 units
Step-by-step explanation:
Perimeter of the given figure = Length of AB + Length of BC + Length of CD + Length of DE + Length of EF + Length of FG + Length of GH + Length of AH
Length of AB = 4.5 units
Length of BC = 2 units
Length of CD = 2 units
Length of DE = 4 units
Length of EF = 5.5 units
Length of FG = 1.5 units
Length of HG = 1 units
Length of AH = 7.5 units
Perimeter of ABCDEFGH = 4.5 + 2 + 2 + 4 + 5.5 + 1.5 + 1 + 7.5
= 28 units

Two boys A and B are a two diametrically opposite points on a circle. at one instant the two start running on the circle
Answers
Step-by-step explanation:
let the distance travel by both be a&b
a has a distance of d1 like wise b
speed=distanc/time
d1=2v
d2=4v
total distance
d1+d2=180
2v+4v=180
6v=180
v=30
d1=2*30
d1=60
d2=4*20
d2=120
now start u get u starting
not that there meet at same point so now calculate the time they will trave in there various direction
time=distance/velocity
but they but move at a standard velocity
Answer:
is this the full question: Two boys A and B are at two diametrically opposite points on a circle. At one instant the two start running on the circle; A anticlockwise with constant speed v and B clockwise with constant speed 2v. In 2 minutes, they pass each other for the first time. How much later will they pass each other for the second time?
if yes than this is the answer:-
A speed = v
B speed = 2v
Time to meet = 2 minutes
d= pi r ( distance they have to run to meet)
they are running towards each other.
(2v+v)
speed = 3v
d=rt
pi*r = 3v*2
r= 6v/pi
circumference = 2* pi*r
=2*pi*(6v/pi)
=12v
...
Now distance to travel to meet = 12v
speed = 3v
t=d/r
t= 12v/3v
t= 4 minutes
I hope this helps a little bit.

What is 566.8 divided by 52
Answers
Step-by-step explanation:
Step 1
The first step is to set up our division problem with the divisor on the left side and the dividend on the right side, like we have it below:
5 5 2
Step 2
We can work out that the divisor (5) goes into the first digit of the dividend (5), 1 time(s). Now we know that, we can put 1 at the top:
1
5 5 2
Step 3
If we multiply the divisor by the result in the previous step (5 x 1 = 5), we can now add that answer below the dividend:
1
5 5 2
5
Step 4
Next, we will subtract the result from the previous step from the second digit of the dividend (5 - 5 = 0) and write that answer below:
1
5 5 2
- 5
0
Step 5
Move the second digit of the dividend (2) down like so:
1
5 5 2
- 5
2
Step 6
The divisor (5) goes into the bottom number (2), 0 time(s), so we can put 0 on top:
1 0
5 5 2
- 5
2
Step 7
If we multiply the divisor by the result in the previous step (5 x 0 = 0), we can now add that answer below the dividend:
1 0
5 5 2
- 5
2
0
Step 8
Next, we will subtract the result from the previous step from the third digit of the dividend (2 - 0 = 2) and write that answer below:
