Step-by-step explanation:

<em>(</em><em>On</em><em> </em><em>Rationalizing</em><em> </em><em>)</em>





Answer:
A
Step-by-step explanation:
The only one you can eliminate on sight is C. You are going to get an x^3 somewhere along the line.
You can eliminate D on sight as well. The x^3 term is 12x^3 not 7x^3
Doesn't leave much does it?
(3x + 2)(4x^2 - 2x - 7)
3x: 12x^3 - 6x^2 - 21x
2 : 8x^2 - 4x - 14
======================= Add
12x^3 + 2x^2 - 25x - 14
Answer: A
(-6,-8) i believe but its difficult without a graph in front of me haha
Answer:
The table cannot be modeled by a linear equation.
Step-by-step explanation:
The data <u>cannot</u> be modeled by a linear equation because the rate of change is <u>not</u> constant.
If grab two set of points from the given data:
Let (x1, y1) = (1, 18)
(x2, y2) = (2, 15)
Plug these values into the slope formula:

Compare this slope with another set of ordered pairs:
(x1, y1) = (4, 12)
(x2, y2) = (8, 9)

As you can see, the rate of change (slope) is not constant. Therefore, the given set of data cannot be modeled by a linear equation.
