15 ( y - 4 ) - 2 (y - 9 ) + 5 (y + 6) = 0
wolverine [178]

Answer:

y = 2/3

Step-by-step explanation:

Assuming you are looking for "y":

15 * ( y - 4 ) - 2 * (y - 9 ) + 5 * (y + 6) = 0

15y - 60 - 2y + 18 + 5y + 30 = 0

15y - 2y + 5y -60 + 18 + 30 = 0

18y = 60 - 18 - 30

18y = 12

y = 12/18

y = 2/3

2 lines form intersecting at a right angle a. form a line b. are parallel b. are perpendicular c. form a ray​
Nonamiya [84]
Two lines intersecting at a right angle would be perpendicular. Parallel lines do not cross or touch each other, and rats don’t form right angles. Perpendicular lines are horizontal and vertical crossing together to form a right angle.

Hope this helps!
