Answer:
Step-by-step explanation:
6y = -3x - 3
y = -1/2x - 1/2
perp. 2
y + 5 = 2(x - 1)
y + 5 = 2x - 2
y = 2x - 7
Answer: 5x - 1 = -6
Step-by-Step Explanation:
We have this diagram here showing numbers and symbols. Just a remainder, "X" is a variable which can be found through and equation of Algebra. Alright, so we have 5 boxes with the symbol "X". Alright, that's a start, so we have <u>5x</u> as a start of the equation. We have <u>-1</u> on the same side as well.
Alright, so on the other side- we have Six symbols of "-1".
That concludes to... <u>-6</u>. Alright, notice how all of the symbols are on a Scale, so we can heavily imply that the "=" symbol will take place between the two sets of symbols. Alright, combining them we get.. <u>5x - 1 = -6.</u>

Answer:
x^2 + 18x + 81 complete's the square.
Step-by-step explanation:
y = [x^2 + 18x + (18/2)^2 ] - (18/2)^2
y = [x^2 + 18x + 81] - 81
y = (x + 9)^2 - 81 This is just to make the completion of the square accurate.
You can't just add something to an expression. You have to balance it out.
