Select the inequality that corresponds to the given graph. a number line graph with a closed circle at negative 6, shading to the left. Choose one answer. a. 3x - 7 < 11 b. -4x greater than or equal to 24 c. -2x + 7 less than or greater to 13 d. 3(x - 2) - 3 greater than or equal to x - 5
Answer is B right?

hmmm
I know for sure that it is not A
-4x >= 24 turns into x <= -6 when you divide both sides by -4 x <= -6 will have shading to the left with a closed circle at -6 so you are correct
Ok thanks
YES!
Solve -3x + 1 > 4 and describe the graph of the solution. Choose one answer. a. x < -1; Open circle on -1, shading to the left b. x < -1; Open circle on -1, shading to the right c. x > -1; Open circle on -1, shading to the left d. x > -1; Open circle on -1, shading to the right
This one is A right?
yes right first subtract one and then divide by -3 so when you divide or multiply by negative number "flip the inequality sign" so yes a is right gO_Od job!!!
Solve: 7(x + 2) > 5x - 10 Choose one answer. a. x > 12 b. x > -6 c. x < -12 d. x > -12
This is D right?
can you show ur work :- )
yes ?? no??
Yes just hang on a second
sure :- )
distribute the 7: 7x + 14 > 5x -10 now add 10 to both sides and subtract 7x from both sides: 14 + 10 > 5x - 7x simplify: 24 > -2x divide -2 (don't forget to switch the sign!) 24/-2 < x simplify: -12 < x
That is what I wrote to my teacher
-12 < x which is the same as x > -12 is correct
Yes
gO_Od job!!! and yes i like that DON'T FORGET THE SIGN!!!!! :-)
Thanks
