Answer:15
Step-by-step explanation:
2(8+7) -3(5)
2(15)-15
30-15
=15
Which recursive formula can be used to generate the sequence
below, where f(1) = 3 and n ≥ 1?
3, –6, 12, –24, 48
The recursive formula for this sequence is
f (n + 1) = –2 f(n)
at n=1 f(n)= 3
at n = 2
f(2) = -2 (3) = -6
n = 3
f(3) = -2 (-6) = 12 and so on
Answer: 24
Step-by-step explanation:
First, find out what z is
6z + 4 = 8z
Subtract the 6z on both sides
4=2z
Divide by 2 on both sides
z=2
Then, find 12z
12*z
12*2=24
Hope this helped!
at x = 0, y = 100, y-intercept
meaning at 0 years, at the very beginning of functioning, the satellite had 100 units of power.
at y = 0, x = 10, x-intercept
meaning, at year 10, the satellite had 0 units of power, already out of power.
A 2 over 3 because 2 and 3 both go in to 6 whereas the others don't.
