Answer:
Step-by-step explanation:
30 = -5(6n + 6)...distribute the 5 thru the parenthesis
30 = -30n - 30....add 30 to both sides
30 + 30 = -30n
60 = -30n....divide both sides by -30
-60/30 = n
-2 = n <===
Yes if he practices X amount of hours and is told to practice X amount of hours than he practiced long enough
![y = mx+b\\\\[m is the slope, b is the y-intercept]\\\\y=\frac{2}{3}x+5\\](https://tex.z-dn.net/?f=y%20%3D%20mx%2Bb%5C%5C%5C%5C%5Bm%20is%20the%20slope%2C%20b%20is%20the%20y-intercept%5D%5C%5C%5C%5Cy%3D%5Cfrac%7B2%7D%7B3%7Dx%2B5%5C%5C)
That means 2/3 is the slope and 5 is the y-intercept.

Answer:
4n+(2n-9)
4n+2n-9
6n-9 =the total age
6n=9
divide by 6 both sides.
n=9/6
n=1.5 years.
substitute the value of n in the age of the father and the daughter.
Age of father=4×1.5
6years.
Age of Daughter = (2×1.5)-9
3-9
=-6 years
Total age
6-6=0
