Step-by-step explanation:
Answer:
10
Step-by-step explanation:
To find the slope subtract the points like the following:
(-27-(-7)/(-2-0)
= -20/-2
=10
So, the slope is 10.
Answer:
- x = ±√3, and they are actual solutions
- x = 3, but it is an extraneous solution
Step-by-step explanation:
The method often recommended for solving an equation of this sort is to multiply by the product of the denominators, then solve the resulting polynomial equation. When you do that, you get ...
... x^2(6x -18) = (2x -6)(9)
... 6x^2(x -3) -18(x -3) = 0
...6(x -3)(x^2 -3) = 0
... x = 3, x = ±√3
_____
Alternatively, you can subtract the right side of the equation and collect terms to get ...
... x^2/(2(x -3)) - 9/(6(x -3)) = 0
... (1/2)(x^2 -3)/(x -3) = 0
Here, the solution will be values of x that make the numerator zero:
... x = ±√3
_____
So, the actual solutions are x = ±3, and x = 3 is an extraneous solution. The value x=3 is actually excluded from the domain of the original equation, because the equation is undefined at that point.

<em>Comment on the graph</em>
For the graph, we have rewritten the equation so it is of the form f(x)=0. The graphing program is able to highlight zero crossings, so this is a convenient form. When the equation is multiplied as described above, the resulting cubic has an extra zero-crossing at x=3 (blue curve). This is the extraneous solution.

Step-by-step explanation:
the equation is y=mx+b
the b part is the y-intercept
so in your equation... the y=intercept would be 7/6
Answer:
The volume of the cylinder is 2002 square units.
Step-by-step explanation:
It is given that,
Height of the cylinder, h = 13 units
Radius of the cylinder, r = 7 units
We need to find the volume of the cylinder. The formula of the volume of cylinder is given by :

So, the volume of the cylinder is 2002 square units.
