Question

Solve the open sentence.

–2 ≤ n + 4 ≤ 7
	
	
 
A.
	

n ≥ 6 and n ≤ –4
	
 
B.
	

n ≤ 2 and n ≤ 7
	
 
C.
	

n ≤ –6 and n ≤ 4
	
 
D.
	

n ≥ –6 and n ≤ 3

anonymous · Answer

Subtract 4 from both sides to isolate the variable n. In the case where n is a negative, you must reverse the greater than or less than symbol, but this is not that case. So the answer is d.
