Find the 7th term in the following sequence (n = 7) f(n) = 8 + 5(n-1)

Also, for this question, state what a1 is (first term) and the common difference (a2 - a1).

n= - 3/5

Step-by-step explanation:

1- Substitute f ( n ) = 0 remove the parentheses

2- Calculate

3- Move the variable to the left

4- Divide both sides

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
