(3x−9x)+(12+8)
Answer
−6x+20
To solve for x, add 3 to both sides, multiply both sides by -1, then take the square both sides.
Answer:
C
Step-by-step explanation:
the rate of change is constant in y (adding 3) and x (adding 2)
When you divide a number by two, you find the number that if you add it to itself, become the original number.
When you square root a number, you find the smaller number that becomes the bigger number if you multiply it by itself.
For sixteen, if you divide it by two, you get 8, while if you square root it, it becomes 4.
Answer:
![C = 82](https://tex.z-dn.net/?f=C%20%3D%2082)
Step-by-step explanation:
Given
-- Rate
-- Principal
-- Time
Required
Determine the compound interest
First, we calculate the Amount (A)
![A = P(1 + R)^N](https://tex.z-dn.net/?f=A%20%3D%20P%281%20%2B%20R%29%5EN)
![A = 800*(1 + 5\%)^2](https://tex.z-dn.net/?f=A%20%3D%20800%2A%281%20%2B%205%5C%25%29%5E2)
Express % as decimal
![A = 800*(1 + 0.05)^2](https://tex.z-dn.net/?f=A%20%3D%20800%2A%281%20%2B%200.05%29%5E2)
![A = 800*(1.05)^2](https://tex.z-dn.net/?f=A%20%3D%20800%2A%281.05%29%5E2)
![A = 882](https://tex.z-dn.net/?f=A%20%3D%20882)
The compound interest (C) is then calculated as:
i.e. Amount - Principal
![C = 882 - 800](https://tex.z-dn.net/?f=C%20%3D%20882%20-%20800)
![C = 82](https://tex.z-dn.net/?f=C%20%3D%2082)
