Answer: 18
For how many months does he go to the gym?
9514 1404 393
Answer:
a4 = 14
Step-by-step explanation:
Use the recursive definition repeatedly.
a1 = 8
a2 = a1 +2 = 8 +2 = 10
a3 = 10 +2 = 12
a4 = 12 +2 = 14
_____
The recursive definition tells you the terms of the sequence have a common difference of 2. The explicit formula for a term of the sequence can be written as ...
an = 8 + 2(n-1)
Then a4 is ...
a4 = 8 +2(4 -1) = 8+6
a4 = 14
Assume that y its Jonah's cash and its initially 3000
y=300
But he spends 25/week. Assume that x is number of weeks.
y=300-25*x - its our function
If we want to find Jonahs cash after 9 week we have to substitute x=9, so
y=300-25*9
y=300-225
y=75$ - its the result
Answer:
slope intercept form of the equation for these points would be y=2x-7
standard form of linear equations for this equation would be: -2x+y=-7
