Answer:
Replace a and b with their given values:
(2(3/5) -1/3) / -6.75/15
2 x 3/5 = 6/5
6/5 - 1/3 = 18/15 - 5/15 = 13/15
13/15 / -6.75/15 = 13/15 x 15/-6.75 = (13 x 15) / (15 x -6.75) = 195/-101.25 = -1 25/27
Answer: -1 and 25/27
We have a function f(x) defined below:
f(x) = (4x²-36x)/(x-9)
We can factor the top:
f(x) = (4x)(x-9)/(x-9)
We see an (x-9) term in the top and bottom. This means that we can reduce f(x) down to:
f(x) = 4x
But we must keep in mind that due to the canceling (x-9) terms, there is a <em>removable discontinuity (hole) at x = 9</em>
To find the zeros of f(x), simple set f(x) = 0 and solve for x:
f(x) = 4x
0 = 4x
x = 0
Choice B
X< -4
You need to do inverse operations and add 12 to both sides.
