Step-by-step explanation:

240 divided by 12 is 20

Answer:

Step-by-step explanation:

In order to solve the question, we have to derivate each function.

1) f(x) = x2 +4x -11

Then,

f'(x)= 2x +4

Now, if f'(4)=0 we would have a critical point, which could be a minimum. Let's find out:

f'(4)= 2*4 +4 = 12 ≠ 0 then this function doesn't not have a minimum at (4, -3)

2) f(x) = –2x2 + 16x – 35

Then,

f'(x)= -4x +16

Now, if f'(4)=0 we would have a critical point, which could be a minimum. Let's find out:

f'(4)= -4*4 16 = 4 ≠ 0 then this function have a critical point at (4, -3)

then,

f''(4) =-4 <0 then we have a minimum at (4, -3)

3) f(x) = x2 – 4x + 5

Then,

f'(x)= 2x -4

Now, if f'(4)=0 we would have a critical point, which could be a minimum. Let's find out:

f'(4)= 2*4 -4 = 4 ≠ 0 then this function doesn't not have a minimum at (4, -3)

4) f(x) =  2x2 – 16x + 35

Then,

f'(x)= 4x -16

Now, if f'(4)=0 we would have a critical point, which could be a minimum. Let's find out:

f'(4)= 4*4 -16 = 4 ≠ 0 then this function doesn't not have a minimum at (4, -3)

well u move all the variables to the left side, so 8x is already in the left but 7x isnt so you move 7x to the left side of the equal sign which makes 7x to -7x.

8x-2-7x=-9

you move the -2 to the right side of the equal sign which becomes +2.

8x-7x=-9+2

you do the math which 8x-7x=1x and -9+2=-7

so.... 1x=-7

and x=-7. Make sure to always combine like terms.

To make sure it is correct replace the x with the -7 and

8(-7)-2=-9+7(-7)

-56-2=-9-49

-58=-58

so x= -7
