Rational Numbers won't be confused into getting to Integers, Whole Numbers, And Counting Numbers. 

Like ALL Counting numbers go into whole numbers, ALL whole numbers go into integers, and ALL integers can go into Rational numbers.

If you go the other way around not ALL can go

There are 8 flowers in a garden. Some insects (butterflies and dragonflies) sit on flowers. There is no more than one insect per
tester [92]

Answer:

4

Step-by-step explanation:

x butterflies and y dragonflies

4 < x + y 《 8

x = 2y

4 < 2y + y < 8

4 < 3y < 8

Only multiple of 2 between 4 and 8 is 6

So 3y = 6

y = 2

x = 2y = 4

10. Kim gets $7 per hour and gets charged $1 for gloves

Use y to represent her pay and x to represent hours worked.

The equation is y = 7x - 1 because she gets 7 times x hours and there is a minus 1 because of the charge of gloves.

11. The table shows that each increasing hour, 8$ is added. Therefore we need to find the bonus that Kit receives just for showing up. This is when hours equals 0. If 3 hours is 27$ pay, then 2 hours is 19$ pay, 1 hour is 11$ pay and 0 hours is 3$ pay. We find that there is a 3$ bonus just for showing up.

Therefore the equation is y = 8x + 3

12. At x = 0, y = 2 so the y-intercept is 2. The slope is going down 4 and right one which means the slope is -4. The y-intercept is b and the slope is m. If we plug these values into the equation y = mx + b we get:

y = -4x + 2

13. At x = 0, y = -3 so the y-intercept is -3. The slope is going up 1 and right 4 which means the slope is 1/4. The y-intercept is b and the slope is m. If we plug these values into the equation y = mx + b we get:

y = 1/4 x - 3
