Step-by-step explanation:
Summation means that you are adding together all the numbers that result from putting in the numbers 5-11 for i:
(-7 - 6(5)) + (-7 - 6(6)) + (-7 - 6(7)) + ( -7 - 6(8)) + ( -7 - 6(9)) + ( -7 - 6(10)) + ( -7 - 6(11)) which gives you the numbers:
-37 + -43 + -49 + -55 + -61 + -67 + -73 = -385

Step-by-step explanation:
<u>Step 1: Define</u>
(6x² - 10x + 9) + (-5x² + 9x - 5)
<u>Step 2: Simplify</u>
- Combine like terms (x²): x² - 10x + 9 + 9x - 5
- Combine like terms (x): x² - x + 9 - 5
- Combine like terms (Z): x² - x + 4
Basically, you move all terms not containing Y to the right side of the equation.
Y=-1.2
