Answer:
2sin^2(3x)
Step-by-step explanation:
Answer:
y = -2/3 x + 5/3
Step-by-step explanation:
y = mx + b
y = -2/3 x + b
1 = -2/3 × 1 + b
3/3 + 2/3 = b
b = 5/3
y = -2/3 x + 5/3
Answer:
The error is the solution.
The solution is all real numbers, or infinite amount of solutions.
Step-by-step explanation:
Step 1: Write equation
-4(2n - 3) = 12 - 8n
Step 2: Solve for <em>n</em>
- <u>Distribute -4:</u> -8n + 12 = 12 - 8n
- <u>Subtract 12 on both sides:</u> -8n = -8n
- <u>Add 8n to both sides:</u> 0 = 0
Here we see that <em>n</em> can equal any number. If you plug in any number <em>n</em>, it will render the equation true. Therefore, our solution is n = infinite amount of solutions.
n = 0 is only slightly correct. 0 does work as the solution, but there are solutions as well.
This looks hard... good luck ! :D
