Answer:
Step-by-step explanation:
<u>Add:</u>
- 4x² - 2x + 6 + 2x² + 4x - 1 = 6x² + 2x + 5
<u>Subtract:</u>
- 6x² + 2x + 5 - 5x² - 2x + 4 = x² + 9
Answer:
2004
Step-by-step explanation:
This equation is in point-slope form. To change it to standard form, you must distribute -1/2 to (x+4) to get -1/2x-2. Your equation should now be y-8 = -1/2x-2. You should then add 1/2x to both sides (to cancel out -1/2x on the right side). Now, you should have y+1/2x-8 = -2. Finally, add 8 to both sides (to cancel out -8 on the left side) and flip the x and the y to get a final answer of 1/2x+y = 6.
