Determine if the lines are parallel, perpendicular or neither:
1. x + 4 = y and y – x = -3
2. y = 4x + 3 and 4y + x = -1
3. y + 3 = 6x and -6x – y = 2
4. 2x + 6y = -3 and 12y = 4x + 20
5. 3x – 4 = y and y – 3x = 8

step-by-step explanation:

i recommend you do what your heart desires. if you're attracted to the same gender, then you're attracted to the same gender. you can't determine what your heart wants.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
