I think the 3rd one, please let me know if I'm wrong. I don't want to give others the incorrect answer.
Step-by-step explanation:
2 x -3(x)- 1(y)- 2 x -1(z)= -5
Answer:
(-3,1,-1)............
B. y=48x+2
C. y=2x−48
D. y=2x+48
Answer:
y = 2X-48
Step-by-step explanation:
Cost to the owner for day's supply of hot dogs,buns and mustard = $48
Profit = $2 profit for each hot dog sold
Let X be the number of hot dogs sold
The profit earned by hot dog stand for X number of hot dogs
y = 2X-48
Answer:
C. y=2x−48

Answer:
- After 2 weeks, Tarik will have $116 saved.
- After 3 weeks, Tarik will have $154 saved.
- After 4 weeks, Tarik will have $192 saved.
- Tarik will have enough money to buy the tablet after 6 weeks.
- The inequality representing the problem is $40 + ($38 * number of weeks) >= $265.49.
Step-by-step explanation:
To represent the amount of money saved after a certain number of weeks, we can use the expression:
Amount of money saved = $40 + ($38 * number of weeks)
Let's evaluate this expression for 2 weeks, 3 weeks, and 4 weeks:
For 2 weeks:
Amount of money saved = $40 + ($38 * 2)
Amount of money saved = $40 + $76
Amount of money saved = $116
For 3 weeks:
Amount of money saved = $40 + ($38 * 3)
Amount of money saved = $40 + $114
Amount of money saved = $154
For 4 weeks:
Amount of money saved = $40 + ($38 * 4)
Amount of money saved = $40 + $152
Amount of money saved = $192
To determine when Tarik will have enough money to buy the tablet, we need to set up an inequality. Let's represent the cost of the tablet as C:
Amount of money saved >= Cost of the tablet (C)
In this case, the cost of the tablet is $265.49. Therefore, the inequality becomes:
$40 + ($38 * number of weeks) >= $265.49
To solve this inequality, we can subtract $40 from both sides:
$38 * number of weeks >= $265.49 - $40
$38 * number of weeks >= $225.49
Finally, we divide both sides of the inequality by $38 to solve for the number of weeks:
number of weeks >= $225.49 / $38
number of weeks >= 5.93 (approximately)
Since the number of weeks must be a whole number, Tarik will have enough money to buy the tablet after 6 weeks.
To summarize:
- After 2 weeks, Tarik will have $116 saved.
- After 3 weeks, Tarik will have $154 saved.
- After 4 weeks, Tarik will have $192 saved.
- Tarik will have enough money to buy the tablet after 6 weeks.
- The inequality representing the problem is $40 + ($38 * number of weeks) >= $265.49.
Which expressions for Step 3 and Step 5 complete the derivation?
Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) + y )
Step 5: cos(x)cos(y) + sin(x)sin(y)
Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) + y )
Step 5: cos(x)cos(y) – sin(x)sin(y)
Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) minus y )
Step 5: cos(x)cos(y) + sin(x)sin(y)
Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) minus y )
Step 5: cos(x)cos(y) – sin(x)sin(y)
Answer:
Option (4)
Step-by-step explanation:
STEP - 1
cos(x + y)
STEP - 2
STEP - 3
STEP - 4
STEP - 5
cos(x)cos(y) - sin(x)sin(y)
[Since, and ]
[Since, cos(-x) = cos(x) and sin(-x) = -sin(x)]
Therefore, Option (4) will be the correct option.

Top Answer was right, don't know why it was rated poorly
The greatest common polynomial of 8r³-6r² is 2r². The expression when factored using the greatest common polynomial becomes 2r²(4r-3).
To find the greatest common polynomial of the expression 8r³-6r², we must look for the greatest common factor or polynomial. In this case, we observe that both terms, 8r³ and 6r², have a common factor of 2r².
To factorize the expression, we simply divide each term by the greatest common factor we identified. The factored expression is 2r²(4r-3).
So, the greatest common polynomial in the given expression is 2r².
