Write the word problem in algebraic form:
n2 -14 = 5n
Write as a quadratic:
n2 - 5n - 14 = 0
Factor:
(n+2)(n-7) = 0
Solve:
n+2 = 0 => n = -2
n-7 = 0 => n = 7
positive solution is 7. (14 less than 72 = 35 which is also 5 times 7)
17.
The point-slope form:

We have slope=m=8, and the point (-5, -3). Substitute:

18.
The formula of a slope:

We have the points (3, 4) and (15, 10). Substitute:

The point-slope form:

or

Answer:
b/(2-3)
Step-by-step explanation:
So we could plot those points, 0, 5. When x is 0, y is 5. When x is 6, y is 0. I think if wrong sorry
