x = 3 - (3×6) + 2. We perform the operation in the bracket first.
x = 3 - 18 + 2
x = -15 + 2 = 2 -15 = -13
x = -13
Answer:
coefficient of x: 2
coefficient of y: 3
coefficient of z: -7
Step-by-step explanation:
To solve this problem, first we need to sum the polynomials A and B, then we need to check the coefficients of x, y and z.
The sum of the polynomials is:
A + B = 5z + 4x^2 - 6y + 2 + 2x + 9y - 12z - 2
A + B = 4x^2 + 2x + 3y - 7z
So, the coefficients are:
coefficient of x^2: 4
coefficient of x: 2
coefficient of y: 3
coefficient of z: -7

Answer:
The inequality is ![25w+200> 750.](https://tex.z-dn.net/?f=25w%2B200%3E%20750.)
Step-by-step explanation:
<u><em>The question is incomplete so the complete question is attached below:</em></u>
Now, to write an inequality that can be used to find
, the number of weeks after starting his collection when Lawrence will have more than 750 baseball cards in his collection.
Let the number of weeks be ![w.](https://tex.z-dn.net/?f=w.)
Number of cards Lawrence purchases each week = 25.
Number of cards Lawrence's father gave him = 200.
Total number of cards Lawrence will have more than in his collection = 750.
Now, to write an inequality that can be used to get the number of weeks after starting his collection when Lawrence will have more than 750 baseball cards in his collection:
![25\times w+200>750](https://tex.z-dn.net/?f=25%5Ctimes%20w%2B200%3E750)
![25w+200> 750.](https://tex.z-dn.net/?f=25w%2B200%3E%20750.)
Therefore, the inequality is ![25w+200> 750.](https://tex.z-dn.net/?f=25w%2B200%3E%20750.)
