Answer:
<em>C = -5</em>
Step-by-step explanation:
<u>Functions</u>
F(x) is defined as:
We know F(-2) is undefined. It comes from the fact that the denominator is 0 for this value of x, thus:
D - (-2) = 0
Solving:
D = -2
Substituting:
We also know F(-1) = 4:
Multiplying by -1
C + 1 = -4
Solving for C:
C = -5
3x³ -2x - 8 = 0

Answer:
B
Step-by-step explanation:
All you have to basically do on this one is go backwards.
The beginning equation is 4x+4=12, so to first revesre the adding we are going to use 12, the product, and subtract 4 from it (since that is what was added).
12-4=8
Now you need to reverse the times 4, so to do that just divide instead because that is the invese of multiplication.
8/4=2
Now you have 2, which is the variable, x. To make sure this is right you can just put it into the equation and see if 4x2+4 is 12
Hope this helped!
Answer:
(2 a - 5) (2 a + 5)
Step-by-step explanation:
Factor the following:
4 a^2 - 25
4 a^2 - 25 = (2 a)^2 - 5^2:
(2 a)^2 - 5^2
Factor the difference of two squares. (2 a)^2 - 5^2 = (2 a - 5) (2 a + 5):
Answer: (2 a - 5) (2 a + 5)
