(3 x a−3/4)∙1/3 if a=3/8
Dennis_Churaev [7]

Answer:

1 3/8

Step-by-step explanation:

Possible derivation:

d/dx(1/8 (-2 + 3 x))

Factor out constants:

= 1/8 (d/dx(-2 + 3 x))

Differentiate the sum term by term and factor out constants:

= 1/8 d/dx(-2) + 3 d/dx(x)

The derivative of -2 is zero:

= 1/8 (3 (d/dx(x)) + 0)

Simplify the expression:

= 3/8 (d/dx(x))

The derivative of x is 1:
