F(x)=5-3x³
f'(x)=-9x²
f'(3)=-81
y+76= -81(x-3)
y+76=-81x+243
y=-81x+167
I remember answering the same question, but you didn't attach any photos. But I remember that the answer is the first one.
I hope I helped. Stay safe and God bless!

2.25c+1.5m context is that 2.25c represents the price of selling bags of cookies, hint the c. 1.5m represents the price of selling muffins, hint the m. In whole the equation represent the amount of money the bake sale would make minus the $25 donation.

Well the first has the angles being 3x+12,x,and 90 so they have to add up to 180 degrees because it is a triangle.
3x+12+x+90 = 4x+102 = 180 solve
4x+102=180
4x=78
x=19.5
Answer:
Following are the answers to this questions:
A) False.
B) False.
C) True.
D) True.
Step-by-step explanation:
In option A,
Let A is 
diagonal matrices that is,
![\left[\begin{array}{ccc}0&1&0\\0&0&6\\0&0&0\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D0%261%260%5C%5C0%260%266%5C%5C0%260%260%5Cend%7Barray%7D%5Cright%5D)
here 
= 0, In this A is the nilpotent matrix and A has three values that are equal to 0 but it is not a diagonalizable matrix.
In option B,
If ![A =\left[\begin{array}{ccc}0&1\\0&0\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D0%261%5C%5C0%260%5Cend%7Barray%7D%5Cright%5D)
in given value A elements are 0 and 1 as a distinct eigen value, that's why A is diagonalizable but |A| =0 its means A is not invertible, that's why it is false.
In option C,
It is given that 
where A~ D, which is A is similar to diagonal matrices, that's why it is true.
In option D,
It is given that A has eigen vector, which leases from 
. A has eigen vector and A is 
matrix, the number of A eigen values = given vector of A, that's why it is correct.
