Answer:
First parabola's vertex is (-2,2), which is a minimum.
Second parabola's vertex is (3,2), which is a maximum.
Step-by-step explanation:
Simply, a vertex of a quadratic is a graph's turning point.
The maximum and minimum can be identified by seeing if the graph curves up or down.
Maximum occurs when your graph is facing down.
Minimum occurs when your graph is facing up.
6) subtract 16 on both sides
then it should be x/4>18
then you would times 18 by 4 and get
c as the answer
7) the answer is d.
because 52-12 is 40 and 52/4 is 13
6% is less than 48%. Due to the reason that 48% is a larger portion.
Answer:
84
Step-by-step explanation:
The mean is calculated as
mean = 
, then
= 21 ( multiply both sides by 4 )
sum = 84
Okay for this question the answer is x=0.
