The axis of symmetry in form
y=ax^2+bx+c is -b/2a
so
y=x^2-5x+4
y=1x^2-5x+4
-b/2a=-(-5)/(2*1)=5/2
the axis of symmetry is x=5/2
Answer:
1/13
Step-by-step explanation:
If there are 52 cards and four aces
4/52=1/13
Meaning that the probability of you drawing an ace is 1/13
Answer:
P(x) = 17
Step-by-step explanation:
P(5) = -3 + 4(5) <- Substitute X
P(5) = -3 + 20 <- Multiply
P(5) = 17 <- Combine Like Terms
Hey there! :D
Let's break this up piece by piece.
The first two, let's say that the first boxes represent the bottom of the chart.
The first far left box would be 13.
The next one 9.
Going across, 10 and 11.
Two more up.
7 and 3.
One more across, which is 4.
So, 13, 9, 10, 11, 7, 3, 4 would be the ones you would want to shade.
I hope this helps!
