Determine whether the graphs of y=-9x+11 and y=1/3x-12 are parallel, perpendicular, coincident, or none of these.

nirvana33 [79]

Answer:

None

Step-by-step explanation:

Parallel means exactly the same just lower or higher(same slope)

Perpendicular means they come together at a right angle, it is evident these do not

Coincident means directly on top of one another which they are not

Since it is none of these than the answer is obviously none of these ;)

I hope this helps u pls give a brainliest and a thx :)

Evaluate f(9) given the function f(x)=3x2 – 11x - 21*

Blizzard [7]

Answer:

123

Step-by-step explanation:

The given function is :

$f(x)=3x^2 - 11x - 21$

We need to find the value of f(9). It can be done by putting x = 9 in the above function as follows :

$f(9)=3(9)^2 - 11(9) - 21\\\\=243-99-21\\\\=123$

So, the value of f(9) is 123.
