Answer:
a
Step-by-step explanation:
-4,0,4,8,12,16
For this case, the first thing we must do is define variables.
We have then:
x: number of times Giselle uses the athletic club
b: amount of money remaining
We write a linear equation of the form:
b = mx + c
Where,
m: slope of the line that represents the cost for each time she uses the athletic club
c: initial amount that Giselle paid
Substituting values we have:
b = -10x + 190
Answer:
a linear function that model the situation is:
d. b = 190 - 10x
From 14 to 24 is 10; from 24 to 34 is 10, and so on, so the common difference is 10.
f(1) = 14
f(2) = 24 = 14 + (2-1)(10) = 14 + (n-1)(10)
So f(n) = 14 + (n-1)(10)
Check: Does f(4) come out to 44, as we expected?
Does 14 + (4-1)(10) = 44? Yes.
Answer:
The second answer is correct
6/11
