To solve this, plug 2b+1 in for a. :
4(2b+1)-5. Solve for b.
First use the distributive property:
8b+4-5=?
Combine like terms:
8b-1=?
Solve for b.
add 1 to both sides.
8b=1
Divide both sides by 8.
b=1/8
For lines to be perpendicular their slopes have to be negative reciprocals of one another, mathematically...
m1*m2=-1...in this case:
y=5x/3=1/3 so the slope of the lines is 5/3 so any line that has a slope of:
5m/3=-1,
m=-3/5 is perpendicular to the original line...
Answer:
true is the answer off this question
