Answer:
2x+1
Step-by-step explanation:
(4-2x), (-7-3x),(11x+6)
Add the three expressions
(4-2x)+ (-7-3x)+(11x+6)
Combine like terms
-2x-3x+11x+4-7+6
6x+3
Divide by the number of expressions which was 3
(6x+3)/3
2x+1
The average is 2x+1
Answer:
x=3y−9
Step-by-step explanation:
Since there is a 70% chance of making $12,000 so have that:
.70 × 12000 = 8400
Also, we have a 10% chance of breaking even, so we also have that:
.10 × 0 = 0
Finally, we have a 20% chance of losing $7400 so we also have that:
.20 × 7400 = 1480
Thus, putting it all together we have:
.70(12000) + .10(0) + .20(7400) = 8400 + 0 + 1480 = 9880
Therefore, the expected value is:
$9880
Answer:
The correct answer is: Option 3.
Step-by-step explanation:
To begin the problem asks to find 
· 
which can be defined as ](https://tex.z-dn.net/?f=%5Bf%2Ag%5D%28x%29)
. Now we are given that:
So now we need to 'multiply' our two algebraic expressions as follow:
Eqn.(1)
The domain of Eqn. (1) is all real numbers of 
.
Which according to the given options , Option 3 is correct.
