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}

Please help me, its due today!!!
zlopas [31]

Answer:

7

Step-by-step explanation:

So we have the expression:

|3x-1|

And we want to evaluate it for x=-2.

So, substitute -2 for x:

|3(-2)-1|

Multiply:

=|-6-1|

Subtract:

=|-7|

The absolute value of a negative is positive. So:

=7

And we're done!
