Perpendicular lines have negative reciprocal slopes. All that means is " flip " the slope and change the sign.
slope = -2, or -2/1....so flip the slope...-1/2...and change the sign...1/2.
so the perpendicular slope would be 1/2.
Not exactly sure which equation you meant:
3(100-b)=6b
300-3b=6b
300=9b
b= about 33
100-3b=6b
100=9b
b=about 11
Answer:
0.15 etc.
Step-by-step explanation:
they are straight lines that make a plus
2r - 4 2(r - 2)
--------- = ----------- = 2
r - 2 r - 2
