Answer:
AC = 38
Step-by-step explanation:
AB = BC
4 - 5x = 2x + 25
-7x = 21
x = -3
AC = 2(BC) = 2(2x + 25) = 4x + 50 = 4(-3) + 50 = -12 + 50 = 38
AC = 38
Add like terms. "Like terms" are those with the same constellation of variables.
.. terms with variable x: 5x +3x = (5 +3)x = 8x
.. terms with no variable: -9 -20 = -29
The simplified form is 8x -29.
Answer:
The answer is C
Step-by-step explanation:
All of the other answers have the same domain and range for the function.
Since it says *10^5, we must multiply the number by 100,000.
To multiply a number by 100,000, move the decimal place of the original number 5 place values to the right. Fill in any necessary zero's.
Final answer: 183,000
Answer:
The expected value of the lottery is $80
Step-by-step explanation:
To get the expected value, we have to multiply each outcome by its probability
Then we proceed to add up all of these to get the expected value of the lottery
we have this as ;;
125(0.2) + 100(0.3) + 50(0.5)
= 25 + 30 + 25 = $80
