Answer:
The answer is 90 songs.
Step-by-step explanation:
Let x be the number she has to transfer, then:
x + 150 =2(210 - x)
x + 150 = 420 - 2x
3x = 420 - 150
3x = 270
x = 90
No, this is because you are subtracting 1/2 in one and adding 1/2 in the other. This will cause two different outcomes
Answer:
f(n) = 100·4^(n-1)
Step-by-step explanation:
The given function c(n) is apparently the multiplier for n days. Its value is 1 for n=1, so we simply need to multiply c(n) by 100:
f(n) = 100·c(n) = 100·4^(n-1)
M = 8 + 1 / -2 - 4 = 9/-6 = 3/-2
y = 3/-2x + b
8 = 3/-2(-2) + b
8 = 3 + b
b = 5
Formula is y = -3/2x + 5
