Answer:
Equation : 
Gallons needed =
gallons
Step-by-step explanation:
It is given that:
Gallons of paint used by Tyler = 
Area of fence painted = 5/7
Let,
x be the whole fence needed to paint.

Because we know that 5/7 of the fence is painted with 5/4 gallons of paint.
Multiplying the equation with 7/5

Therefore,
Equation : 
Gallons needed =
gallons
M = 20/-4 = -5
Sub in (-4,0): 20+b = 0 ->b = -20
So, y = -5x - 20
Answer:
3
Step-by-step explanation:
Evaluating the limit of the function 9n - 3n / 2n.
First we factor out n from the numerator of the function to have
F(n) = n(9-3)/2n
Cancelling the variable n at the numerator with the one at the denominator we have:
Iim f(n) = 9-3/2
Iim f(n) = 6/2
Lim f(n) = 3
This shows that the limit of the function given is 3 no matter what the variable x is tending to.
