(x , 5/2)......so y = 5/2.....so do some subbing

y = x - 1/2
5/2 = x - 1/2....add 1/2 to both sides
5/2 + 1/2 = x
6/2 = x....reduce
3 = x

now check it...(3, 5/2)
y = x - 1/2
5/2 = 3 - 1/2
5/2 = 6/2 - 1/2
5/2 = 5/2 (correct)

so x = 3 <==

Suppose 20 students delegates will attend the conference. Each school should be represented fairly in relation to it's populatio
algol [13]

Answer:

To find out the number coming from each school, you need to use the proportion of the school's population out of the population of all three.

Total population = 618 + 378 + 204

= 1,200 students

North Middle school:

= 618/1,200 * 20

= 10 students

Central Middle School:

= 378 / 1,200 * 20

= 6 students

South Middle School:

= 204/1,200 * 20

= 4 students

Hello everyone I need help with this worksheet it's ten problems answer the ones you know for me please it's homework.
Fed [463]

Answer:

1. Slope = -4/5

2. Slope = 2/3

3. Slope = 0

4. Slope = 3/-4

5. Slope = 7/-12

6. Slope = 1/2

7. Slope = -2/0 --> Undefined

8. Slope = 3/-2

9. Slope = 5/-4

10. Slope = 4/3

Step-by-step explanation:

Ok so I'm assuming that you want the slope for all the two points. Basically, the formula for slope is rise/run, or y2-y1/x2-x1. Solve using that. For example, for number 1, it would be:

10-2/1-11 = 8/-10 = -4/5
