The formula for axis of symmetry is -b/2a.
For f(x):
0/2(4)
0/8
Axis of symmetry= 0
For g(x)
-(-8)/2(1)
8/2
Axis of symmetry= 4
For h(x)
-(-12)/2(-3)
12/-6
Axis of symmetry= -2
Order from least to greatest: -2, 0, 4
Final answer: h(x), f(x), g(x)
Answer:
I think B
Step-by-step explanation:
the answer I got is 5.184
50*8=400
400+175=575
it subtracted 575 on the last round
Answer:
Equations:
--- Cindy
--- Ruben
Solution to equation:
Time they have the same amount: 14 minutes
Number of cards they have at that time: 140 flashcards
Step-by-step explanation:
Solving (a): Variables and what they represent
The variables to use are x and y
Where x represent the minutes and y represents the number of flashcards in x minutes
Solving (b): System of linear equation
Cindy:
per minute
Total number of flashcards (y) in x minutes is:
Ruben:
per minute
Total number of flashcards (y) in x minutes is:
Solution to Equations:
Time they have the same amount.
To do this, we expressions
i.e.
Collect Like Terms
Number of cards they have at that time.
Here, we simply substitute 14 for x in any of the equations.
or
Well, for
solving system of equations, we can use either substitution where we plug one
equation into the other, or elimination where we combine the equations.
-
Using elimination,
you would to eliminate one variable from both equations, so you automatically would
get one equation with one variable!
