We can split them up
dy/dx-12x²=-12 times dy/dx x²=-12 times 2x=-24x
dy/dx9x=9 times dy/dx x=9 times 1=9
so
f'(x)=-24x+9
f'(6)=-24(6)+9
f'(6)=-144+9
f'(6)=-135

Proper fractions for 3(5/8) = 29/8.
<u>Step-by-step explanation:</u>
The given fraction can be converted into improper fraction as the numerator will be greater than the denominator.
3 is multiplied by 8 and then it is added to 5,
we will get 29,
and
3 (5/8) = ((3×8)+5)/8
= (24+5)/8
= 29/8
so finally 29/8 is the answer.
