Answer:
She spent 17 books
Equation: 45+6 = 51 and 51/3 = 17 books
Answer:
Step-by-step explanation:
The given line has a slope m = 4.
We know parallel lines have equal slopes.
<u>Use point - slope equation and substitute the coordinates of the given point to get:</u>
- y - 5 = 4(x - 4)
- y - 5 = 4x - 16
- y = 4x - 16 + 5
- y = 4x - 11
S = n(a1 + an)/2
2S = n(a1 + an)
2S = na1 + nan
nan = 2S - na1
an = (2S - n a1)/n
