Step-by-step explanation:
The first one (f×g)(x) is asking you what is f of x times g of x. This means you multiply the function. You can multiply by the first term (5x) then the second (3) and combine like terms.


Combine like terms

The second one asks you to divide.
Factor out f(x):

From dividing f(x) /g(x)

To

Cancel like terms since (5x+3) is on top and bottom of fraction.
You get 3x+2
Answer:
$2522; if her sister put in 1/3 of Daniella's original money.
But if you don't combine Daniella's original money it would be $2328
Step-by-step explanation:
582 x 3= 1746.
and 1/3 of 582= 194
582+1746+194=2522
Because it says "not black" we would do white marbles
There are 15 white marbles and a total of 20
So the fraction of white marbles to total would be 15/20
Because the answer is wanted as a decimal divide 15 by 20
15/20=.75
There is a .75 chance that she will not draw a black marble
