Answer:

f(x)=4×-2,g(x)=2(x)+8

h(x)=f(x)+g(x)

solution:

h(x)=f(x)+g(x)

=4x-2+2x+8

4x+2x=8+2

6x=10

6x/6=10/6

x=5/3

Each time, you take out one ball from the box and then put it

Answer:

40/3087

Step-by-step explanation:

First, we need to count the number of each type of numbered ball.

Ball Counts: 1 - 5 balls; 2 - 2 balls; 3 - 1 ball; 4 - 2 balls; 5 - 4 balls; 6 - 3 balls; 7 - 1 ball; 8 - 2 balls; 9 - 1 ball, there are then a total of 21 balls

Next, you need to find the probability of each event.

Get less than 4

p(<4) = (5+2+1)/21

p(<4) = 8/21

Get less than 2

p(1) = 5/21

Get exactly 6

p(6) = 3/21

p(6) = 1/7

Next, we need to find the probability of all three events by multiplying the probabilities together.

p(all three) = (8/21)*(5/21)*(1/7)

p(all three) = 40/3087

The probability of all three events occurring is 40/3087.

Answer:

$-3x^3+x$

Step-by-step explanation:

Let's first write the expression:

$-3x+x^3-2x^2-(4x^3-2x^2-4x)$

Now we can simplify. Be sure to remember to distribute the "-" to all the numbers in the parentheses. You can picture it like multiply "-1" to all the numbers in the parentheses to make it easier.

$-3x+x^3-2x^2-4x^3+2x^2+4x$
