Answer:
Right answer is choice D.
Answer:
4 + (-10)
Step-by-step explanation:
for the answer you are taking adding TEN negatives from a non negative number. So we subtract 4 - 10 this equals -6 which is the same as -10 - (-4)
The answer is D.
First, separate the compound equality into 2
1st -3 (x-4) greater than/ equal to 21
2nd -3( x-4) < 30
Second, solve the inequality for x
1st x less than/ equal to -3
2nd x > -6
Third, find the intersection
D. -6 < x (less than/equal) to -3
I hope this helped, and if you don’t mind, giving me brainiest!
