Answer: infinitely many solutions.
Step-by-step explanation:
Ok, our equation is:
-2.1*b + 5.3 = b - 3.1*b + 5.3
now, simplifyng the right side, we have:
b - 3.1*b + 5.3 = (1 - 3.1)*b + 5.3 = -2.1*b + 5.3
Then our initial expression is:
-2.1*b + 5.3 = -2.1*b + 5.3
So in both sides of the equality we have the exact same thing, so this is a trivial equality.
This means that the equality will remain true for any value of b, which means that we have infinitely many solutions.
The possible other could be 20
Answer:
-9/2
Step-by-step explanation:
Find the slope of the line first then it's negative reciprocal will be what you're looking for.
m=8-6/6--3=2/9
Perpendicular slope=-1/2/9=-9/2
40 and 40 and 100 is one set
Another is 40 and 70 and 70
