Answer:
in steps
Step-by-step explanation:
DE // BC
m∠ADE = m∠ABC and m∠AED = m∠ACB
∴ ΔADE similar to ΔABC
AB/AD = AC/AE
(AD + DB) / AD = (AE + EC) / AE
AD/AD + DB/AD = AE/AE + EC/AE
1 + DB/AD = 1 + EC/AE
DB/AD = EC/AE (AD/DB = AE/EC)

Answer: 5</h3>
The coefficient is the term just to the left of the variable. So for the term 5y, the number to the left of y is 5.
extra info: 5y is the same as 5*y or "5 times y", where y is a placeholder for some unknown number.
Answer:
If the slope is positive it is increasing if the slope is negative it is decreasing :)
Example:
Y=mX+b
If m is positive it is a positive slope
You do 27 divided by 90 27/90=0.3 and then move the decimal two places which would give you 30%
