: Hope this helps :)
It is given in the question that,

Since we have the value of r given, so we have to use the formula to find the nth term of the geometric progression, which is

Substituting the values of a and r, we will get

So the correct option is the third option .
Answer:
X+6
Step-by-step explanation:
Combined like terms.
Answer:
The y value of a point where a vertical line intersects a graph represents an output for that input x value. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output.
A.) 7y+14. Because 7 is the amount he will increase each year (y) so 7y represents each year added, plus 14 (the amount he already can do per minute)
