Answer: 30y - 25b +5
Step-by-step explanation:
(look at attachment image fir explanation)
Simplifying
p + -4 = (-9) + p
Reorder the terms:
-4 + p = (-9) + p
-4 + p = -9 + p
Add '-1p' to each side of the equation.
-4 + p + -1p = -9 + p + -1p
Combine like terms: p + -1p = 0
-4 + 0 = -9 + p + -1p
-4 = -9 + p + -1p
Combine like terms: p + -1p = 0
-4 = -9 + 0
-4 = -9
Solving
-4 = -9

Answer:
Lines BC and F represent perpendicular lines
Step-by-step explanation:
we have
<em>Line BC</em>

the slope of the line BC is 
<em>Line F</em>

the slope of the line F is 
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
so

we have
-----> slope line BC
-----> slope line F
Find the product of their slopes

therefore
Lines BC and F represent perpendicular lines
