Answer:
d = 7.2
Step-by-step explanation:
We can cross multiply the equation to get:
6 * 30 = 25 * d
(* is multiplication sign by the way)
180 = 25d
Divide both sides by 25 to get:
d = 7.2
Answer:
y = -x -1

x1= 0, y1= -1

-1 = x/(y+1)
-1 (y+1) = x
y+1 = -x
y= -x -1
Take notes and pay attention since just slacking off for only 10 minutes can get you behind and struggling.
