Step-by-step explanation:
this is clearly not a linear sequence (the terms don't have the same difference).
so, it has to be a geometric sequence.
the common ratio is r.
s2 = s1 × r
16 = 64 × r
r = 16/64 = 1/4
control :
s3 = s2×r
4 = 16 × 1/4 = 4
correct.
Answer:
P(x) = 3x - 150
Step-by-step explanation:
● P(x) = R(x) - C(x)
We khow that:
● R(x) = 5x
● C(x) = 2x + 150
● P(x) = 5x -(2x+150)
● P(x) = 5x - 2x -150
● P(x) = 3x - 150
Answer:
x =
Step-by-step explanation:
Given
4x - - 2x - =
Multiply through by 6 to clear the fractions
24x - 5 - 12x - 1 = 4
12x - 6 = 4 ( add 6 to both sides )
12x = 10 ( divide both sides by 12 )
x = =
