Nine and a half times.
***
you can put it fully nine times. You reach 18 like this. But you have 1 more to go until 19! So, just cut the 2 in half to get 1, and put that in!

Answer: 9

Step-by-step explanation:

It can only fully go into 19, 9 times (2*9=18 and 2*10=20). However if you can use decimals or fractions 2 can go into 19 9.5 times or 9 1/2 times (9.5 is equal to 9 1/2. 9.5*2=19)

Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of the function y = 4x2 – 8x – 3.
Schach [20]
Axis of symmerty from form
ax²+bx+c is -b/2a
the axis of symetry is the x value of the vertex so just put the axis of symetry for x an evaluate


4x²-8x-3
-b/2a=-(-8)/(2*4)=8/8=1

input for x
4(1)²-8(1)-3=4-8-3=-7

(1,-7) is vertex
