Solve the following inequality algebraically. ∣x−9∣≥4

Step-by-step explanation:

So we have the inequality:

Definition of Absolute Value. Since this is "greater than," we need to use "or."

Also, note that we flip the inequality on the second equation because we multiplied by a negative.

Add 9 to both equations:

And that's our solution.

And we're done!

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

80 the answer is 80
