70℅ = 14
100 = X
70X = 1400
X = 1400/70
X = 20
20 Euros is the full price
can you translate it to engish, i might help!
1) factor the denominators: 2b/(b-1)2 - 2/ (b-1)2
2) MAKE SURE YOU HAVE A COMMON DENOMINATOR
3) combine the numerators: 2b-2/(b-1)2
4) distribute 2 from numerator: 2(b-1)/(b-1)2
5) simplify; answer is 2/(b-1)
The slope is 4/3.
rise/run
rise = 4
run = 3
