Help!! Math question ASAP!!!!
The sum of a number and twice the second number is 24. Determine the two numbers to maximize their product. Show your work (equations, calculations, etc.) If it is easier to describe in detail what you did rather than show something (such as using your calculator), you may do so.

Answer:
The answer is: expected value is -$0.88
Step-by-step explanation:
Given is, the he bidding starts at 1¢ and goes up 1¢ at a time. A television that is worth $2000 is won, on average, with a bid of $160. So, $160 in 1¢ steps means 16000 bids.
Therefore, a person invest $1 with a 1/16000 probability of a $2000 return.
Noe, the expected value will be =
= -1+0.125 = -0.875 ≈ -$0.88
Hence, the answer is -$0.88

2.35 / 3.45
1.10 / 3.45
294.20 / 3.45 x 1.10 = 93.80 to 4sf
294.20 / 3.45 x 2.35 = 200.40 to 4sf
93.80 + 200.40 = 294.20
93.80 / 1.10 = 85.2727272727
200.40 / 2.35 = 85.2765957447
85 + 85 = 170 need two more
84 x 1.10 = 92.40 84 x 2.35 = 197.4
88 x 2.35 = 206.8 88 x 1.10 = 96.8
= 299.2 = 294.20

Answer:
x = 6
Step-by-step explanation:
The x-intercept of the equation is where the graph crosses the x-axis when y = 0. So, we simply plug in 0 for y:
2(0) - x = -6
0 - x = -6
-x = -6
x = 6
Alternatively, you can graph the equation into a graphing calc and analyze where the graph crosses the x-axis.

Answer:
product y ³ - 64 and a = 16.
Step-by-step explanation:
Given : (y — 4)(y² + 4y + 16) .
To find : Using the distributive property to find the product a polynomial of the form y³ + 4y² + ay – 4y² – ay – 64. What is the value of a in the polynomial?
Solution : We have given
(y — 4)(y² + 4y + 16) .
Distribute y over (y² + 4y + 16) and - 4 over (y² + 4y + 16).
y (y² + 4y + 16) - 4 (y² + 4y + 16).
y ³+ 4y² + 16 y - 4y² - 16y - 64.
This is in form of y³ + 4y² + ay – 4y² – ay – 64.
Here, a = 16.
Product : combine like terms
y ³+ 4y² - 4y² + 16y - 16y - 64.
y ³ - 64.
Therefore , product y ³ - 64 and a = 16.
