Answer:
The only solution I see is for x=0
Step-by-step explanation:
y=8x+2
y=-8x+2
y=y so substitute:
8X+2=-8X+2
Subtract 2 from each side
8X=-8X
divide each side by 8
x=-x
The only solution I see is for x=0

Answer:
x = 2
Step-by-step explanation:
The square of the tangent is equal to the product of the secant lengths to the near and far circle intersections.
(x +4)² = (2x -1)(2x -1 +9)
0 = (2x -1)(2x +8) -(x +4)² = (4x² +14x -8) -(x² +8x +16)
0 = 3x² +6x -24 = 3(x² +2x -8) = 3(x +4)(x -2)
This has solutions x = -4 and x = 2. Only the latter works in this geometry.
x = 2
Answer:
-48
Step-by-step explanation:
(-12)•4 = -48
Plug in the 6 and -1 to get the answers
f(6)=120
