Answer:
yea its in the book
Step-by-step explanation:
8 / (7/8) =
8 * 8/7 =
64/7 =
9.14.....so he can cut 9 full pieces
That is so confusing the way theyou word it sometimes is like what the...what?
Answer:
its 45 degrees celcius
Step-by-step explanation:
The x coordinate of the vertex will be the average of the two zeros, here -3 and 5, so x=(-3+5)/2 = 1, f(1)=(1+3)(1-5) = -16.
Answer: (1, -16)
Let's do it some other ways. How about completing the square to turn f in to vertex form?
f(x) = (x+3)(x-5) = x² - 2x - 15 = (x² - 2x + 1) - 1 - 15 = (x-1)² - 16
and now we can read off (1, -16) as the vertex.
The other method is the vertex is x= - b/2a = - (-2)/2(1) = 1.
Three methods, same answer. Good.
