The combined total profit is (17x + 2502) dollars
<em><u>Solution:</u></em>
Profit for each Mp3 player = $ 35
Profit for each DVD player = $ 18
Let x be the number of MP3 players sold last week
Number of MP3 players = x
Last week, Techwiz sold a combined total of 139 MPS and DVD players
Total number of mp3 and dvd sold = 139
Number of DVD player = 139 - x
<em><u>Write an expression for the combined total profit (in dollars) Techwiz made from MP3 and DVD players last week.</u></em>
Combined total profit = Number of MP3 players x Profit for each Mp3 player + Number of DVD player x Profit for each DVD player
Thus the combined total profit is (17x + 2502) dollars
Answer:
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal or initial amount of money invested.
R represents interest rate
T represents time
Considering the investment on account A,
I = $6.94
R = 3.7%
T = 9 months = 9/12 = 0.75 years
6.94 = (P × 3.7 × 0.75)/100 = 0.02775P
P = 6.94/0.02775 = $250
Considering the investment on account B,
I = $13.80
R = 2.3%
T = 18 months = 18/12 = 1.5 years
13.8 = (P × 2.3 × 1.5)/100 = 0.0345P
P = 13.8/0.0345 = $400
To determine the account that earned more interest in the first month,
250/9 = $27.8
400/18 = $22.2
Account A earned you the most interest the first month because $27.8 is higher than $22.2
F(x) will = 0 when either x = 0 or x = 8. Here's how you know.
if x = 0 then 0 * (x - 8) = 0 because anything multiplied by 0 is zero.
if x = 8 then 8 * (8 - 8) = 8 * 0 = 0

Answer:
(no solutions)
Step-by-step explanation:
Solve for x:
abs(x + 3) = -10
Hint: | Show the equation has no solution.
By definition, absolute value is positive. Therefore abs(x + 3) = -10 has no solution:
