Question

SAMPLE:
Part 1: The solution is x > 5 and x<=9.
Part 2: There would be an open circle on 5 and a closed circle on 9.
Part 3: The shading is between the two numbers.
Be sure that you have included all three parts when answering each question.

"Greater than or equal to" would be typed >=.
"Less than or equal to" would be typed <=.

1. d - 1 > -3 and d + 2 < 5

2. -3k + 7 > -5 and -7k + 5 < -2

3. -5 < 2y - 3 < 23 (Hint: refer to example 2 in the lesson.)

4. x - 4 < 5 or x + 2 > 15

5. 5x - 4 > 6 or -4x + 5 > 1
May someone please help me!

Answer 1

@raffle_snaffle can you help me?

Answer 2

a closed circle means greater than or equal to, or lessor than or equal to
since these in part 1 only show greater than or lessor than they are open circles
x is true when it is greater than 5 and less than 9
are you able to draw the graph?

Answer 3

or is that just a sample?

Answer 4

the top one is a sample the bottom one is what i am suppose to do.

Answer 5

1. d - 1 > -3 and d + 2 < 5
Solve for d in both equations
d - 1 > -3
+1 to both sides...
what is the new inequality?

Answer 6

d-1 +1 > -3 +1
=?

Answer 7

I'm lost

Answer 8

-2

Answer 9
