For this case, the first thing we must do is define a variable.
We have then:
n: number of days.
We now write the explicit formula that represents the problem.
We have then:
an = 4n + 15
Where,
15: crunches the first day
4: increase the number 4 each day
Answer:
An explicit formula for the number of crunches Abbie will do on day n is:
an = 4n + 15
Answer:
A. -7
Step-by-step explanation:
The y-intercept of a line is where the line <em>intercepts</em> the y-axis. The y-intercept is shown, in point form, (0,y), y being where the line intercepts the y-axis.
If I did it right, it is 120
17/4 This is what I would choose
-3/2
