Answer:
Option D
Step-by-step explanation:
Increasing intervals represent the inputs that make the graph rise, or the intervals where the function has a positive slope. Decreasing intervals represent
the inputs that make the graph fall, or the intervals where the function has a negative slope.
The inputs ( − values) that make () rise are
(-2,∞)
Hi there!

We can begin by making each fraction have a common denominator:
If we make each have a common denominator of ab, we get:

Simplify:

Multiply both sides by ab:

Move b to the opposite side:

Factor out b:

Divide by (ac - 1):

Answer:
x = 4±sqrt(19)
Step-by-step explanation:
Assuming you meant x^2 -8x = 3
Take the coefficient of x
-8
Divide by 2
-8/2 =-4
Square it
(-4)^2 = 16
Add this to each side
x^2 -8x +16= 3+16
The number inside the square term is the coefficient divided by 2
(x-4)^2=19
Take the square root of each side
sqrt((x-4)^2=±sqrt(19)
x-4 = ±sqrt(19)
Add 4 to each side
x-4+4 = 4±sqrt(19)
x = 4±sqrt(19)
