Question

solve inequality and graph solution
-3e - 10 less than or equal to -4

-3e - 10 +10 less than or equal to -4 +10
-3e less than or equal to 5
-3e/3 less than or equal to 5/3
e less than or equal to 1.6666

Answer 1

-4+10 should be 6 not 5

Answer 2

Then when you divide by -3, it flips the inequality sign

Answer 3

\[-3e \le 6\]

\[e \ge -2\]

Answer 4

ok I got it so I would have an open circle on -2 and it would go towards the positive side

Answer 5

Shaded circle since its less than or EQUAL to, and yes shading to the right

Answer 6

so you would flip the sign if the other side is positive correct

Answer 7

You flip the sign whenever you divide or multiply by a negative number

we divided by -3 so we flipped the sign

Answer 8

so did I do this one right 15 less than or equal to 3 -4s
15-3 less than or equal to 3-3 -4s
12 less than or equal to -4s
12/-4 great than or equal to -4s/-4
-3 great than or equal to s
since this is not true it would be an open circle towards the negative

Answer 9

You're right with \[-3 \ge s\]

but it would be shaded circle on -3, shading to the left

Answer 10

oh is it because the -3(-4) would be 12

Answer 11

No, its because s is less than or equal to -3

so that means -3 and everything less than it is included

Answer 12

ok thanks
