ale4655 [162]

Answer:

$a=\frac{8}{9}$

Step-by-step explanation:

$3^x-3x^{x-2} =a3^x$

Divide both sides by $3^x$ :

$3^{x-x}-3^{x-x-2}=a$

Simplify:

$3^0-3^{-2}=a\\a=1-\frac{1}{9} \\a=\frac{8}{9}$

What is the rate of A, what is the rate of B, which equation has a greater rate?

11Alexandr11 [23.1K]

Answer: Rate of A: 5/6

Rate of B: 3/5

A has a higher rate of change

Step-by-step explanation: You calculate slope/rate of change by determining the rise over the run. The rate of change in A is 5/6x, this is bigger than the slope of B.
