Answer:
D: 7.6
Step-by-step explanation:
If you count it is 7 so i put 7.6
Could be 21. Try replacing function designators with the actual functions.

Answer:x>7 or x ≤ -3
Solving the 1st inequality
-6x +14 < -28 --------------- (Collect like terms)
-6x < -28 - 14
-6x < - 42 -------------------- (Divide both sides by -6)
Note: If you decide an inequality expression by a negative value, the inequality sign changes)
-6x/-6 > -42/-6
x > 7
Solving the 2nd inequality
9x + 15 ≤ −12 ----------- (Collect like terms)
9x ≤ −12 - 15
9x ≤ −27 ------------------(Divide both sides by 9)
9
9x/9 ≤ −27/9
x ≤ -3
Bring both results together, we get
x>7 or x ≤ -3
The final result is complex (i.e. can't be combined together).
Step-by-step explanation:
Answer:
Step-by-step explanation:
We start by subtracting 
from both sides of the second inequality:
Therefore, we conclude that:
Therefore, every point that satisfies the system has a 
-coordinate greater than 
.
