Answer:
The 3rd one
Step-by-step explanation:
Answer:
where is the graph? makes no sense
X^2-4x+5=8 so let's complete the square, subtract 5 from both sides
x^2-4x=3 halve the linear coefficient, square it, and add it to both sides...(-4/2)^2=4
x^2-4x+4=7 now the left side is a perfect square of the form
(x-2)^2=7 take the square root of both sides
x-2=±√7 add 2 to both sides
x=2±√7
So A. is your answer.
Answer:
C because the line doesn't touch the x axis
Step-by-step explanation:
If the 4th lies opposite the 11th, then you know the 3rd lies opposite the 10th, the 2nd opposite the 9th, and the 1st opposite the 8th; meanwhile, in the reverse direction you'd find that the 5th lies opposite the 12th, the 6th opposite the 13th, and the 7th opposite the 14th. Move up one more bead and you're back at the 1st, which you already know lies opposite the 8th. Therefore there are 14 total beads.
