Answer:
Step-by-step explanation:
1) UP
2) (2, -4)
3) x = 2
4) minimum
5) y = -4
6) Real numbers
7) -∞ ≤ x ≤ ∞, y≥ -4
8) y = -3
9) x = -2, x = 6
10) ∞
The first one is the last answer because you subtract 18 and when you divide you change the inequality symbol
the second one is the last answer for the same reason
the 3rd one is x<-1.25
the 4th one is x<8/15
Answer: Debería ser 7
Step-by-step explanation:
The student is not correct.
Absolute value means distance from zero
|-9| = 9
|4| = 4
Since 9 is greater than 4,
|-9| is greater than |4|
In other words, -9 is further from zero then 4
