Answer:
D
Step-by-step explanation:
Yes.
Answer:
f(x) = 2x² - 8x - 10.
This is a parabola open upward (since a>0) with an axis of symmetry = -b/2a:
a) axis of symmetry: x = -(-8)/(2*2) = 8/4 = 2. Then x = 2, which is the x component of the vertex
b) for x = 2, f(x) = f(2) = - 18 (component of y of the vertex)
c) VERTEX(2, - 18)
d) DISCRIMINENT: b² - 4.a.c = 64 - 4*2*(-10) = 144
Hope this helps! :)
<span>4x – 9y = –36
-9y=-4x-36
take minus out
9y=4x+36
y=1/9(4x+36)
y=4/9x+4.............answer
y=mx+c is slope intercept form

Answer:
If 22 is an option, go with it. I am pretty certain it is correct.
Step-by-step explanation:
Find pie for both circles
13 x pie = 40.8
6 x pie = 18.8
40.8 - 18.8 = 22
