Answer:
The slope is positive 5.
Step-by-step explanation:
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

Answer:
b = -2
Step-by-step explanation:
Given expression:
9(b - 4) - 7b = 5(3b -2)
Using distributive properties, open the parentheses;
9b - 36 - 7b = 15b - 10
2b - 36 = 15b -10
collect like terms;
2b - 15b = - 10 + 36
-13b = 26
Divide both sides by -13;
b = -2
