Answer:
true for all x
Step-by-step explanation:
3x - 4 ≤ 2
Add 4 to each side
3x - 4+4 ≤ 2+4
3x<6
Divide by 3
3x/3 <6/3
x<2
or
2x + 11 ≥ -1
Subtract 11 from each side
2x + 11-11 ≥ -1-11
2x≥ -12
Divide by 2
2x/2 ≥ -12/2
x ≥ -6
x<2 or x ≥ -6
true for all x

Answer:
4. x= -6
5. x= 7
6. x= -18
7. x= 8
8. x= 7
I'll do 9 and 10 in a separate answer
Step-by-step explanation:
4. Multiplying a negative with another negative always equals a positive, so replace x with -6, multiply -6 and -3 and you'll get 18.
5. To make it simple, think "what minus 3 equals 11?" So in this case, multiplying 2 by 7 would = 14, and that minus 3 is 11.
6. Divide a negative by a positive to get a negative answer. -9 + 6 = -3, but first we have to get 9. So since the fraction is x divided by 2, you'd replace x with -18 to get -9.
7. -3 x 8 is -24, + 11 is -13.
8. What minus 7 equals 21? 28. So replace x with 7. (7 x 4 = 28), subtract 7 from 28, and then you'll have 21.
You would do 20-(-25) which would make it 20+25 so the answer is 45 degrees
