of her earnings for entertainment,
1

for presents, and the rest she plans to save. What percentage of her earnings has Shanika planned to save?
this ones a bit interesting. given a(n) = 5 - 3n consider this:
a(n-1) = 5 - 3(n-1)
= (5 - 3n) + 3 => but a(n) = 5 - 3n, the first term
= a(n) + 3 => subtract 3 from both sides
a(n-1) -3 = a(n)
or
a(n) - a(n-1) -3

Answer from: Quest
the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .

Answer:
the image is given below
step-by-step explanation:
since the options are not given so we draw it from the equation
the given equation is
y = (x-1) (x+4)
y = y² + 3x - 4
the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
