2x-3y= -4 because 2x=8 since x=4 so,
8 - 3y = 20
-8. -8
-3y = 12
————
-3
y = -4
Answer:
2, 4, 5, and 6 have the same pair of solutions.
Step-by-step explanation:
1. n(n+3)(n-4) = 0
2. 2n(4n+6)(6n-4) = 0
3. 2n(6-4n)(4n-6n) = 0
4. n(2n+3)(3n-2) = 0
5. 2n(2n+3)(3n-2) = 0
6. 3n(6n+9)(9n-6) = 0
Answers:
1. n = 0, -3, 4
2. n = 0, -3/2, 2/3
3. n = 0, 3/2
4. n = 0, -3/2, 2/3
5. n = 0, -3/2, 2/3
6. n = 0, -3/2, 2/3

Step-by-step explanation:
Answer:
The value of the computer is given by 900(0.7)^t.
Step-by-step explanation:
A computer sells for $900.
If the price of the computer loses 30% of its value per year, then it is compounded every year.
Now, the price of the computer t years after it is sold will be
900(1 - 30/100)^t = 900(0.7)^t ........... (1)
Therefore, the value of the computer is given by the above equation (1). (Answer)
