Question

I have 3 questions to ask :

1.List all of the integer values of x that are part of the solution set for the following inequality: −5≤x<−2 .

2.List all the POSITVE integers that are in the solution set for 1≤x<3 .
List all the NEGATIVE integers that are in the solution set for −4≤y<−1 .

3.Lyon bought some bracelets and an necklace for his younger sister. He bought 5 bracelets that each cost the same amount and a necklace that cost $3.50. Lyon spent less
than $13 altogether.

Which inequality can be used to find the cost of each bracelet?
a .5b+3.50>13
b .5b−3.50>13
c. 5b+3.50<13
d. 5b−3.50<13

What is the highest possible price of each bracelet?

Answer 1

-5≤x≤-2 so

x=[-5,-2)

x={-5, -4, -3}

...

1≤x<3

x=[1, 3)

x={1,2}

-4≤y<-1

y=[-4,-1)

y={-4, -3, -2}

...

5b+3.50<13

Answer 2

1.> -5,-4,-3
2.> 1,2. and -4,-3,-2
3.> 5b + 3.50 < 13
