Answer:
B is the correct answer
Step-by-step explanation:
Let’s write the equation for Tim according to the question, that is t = 14h
Now for sheri, looking at the table, we can see that in two hours, he sells 14 tickets . This means that he sells at an average rate of 7 tickets per hour
Modeling his selling rate, with t being the number of tickets and h being the number of hours, we have;
t = 7h
Tim’s rate is t/h = 14
While sheri’s rate is t/h = 7
We can see that Tim’s rate is double Sheri’s rate
The exact value of f(n - 1) is fn - f

Answer: B) y = -5x+5</h3>
slope = -5, y intercept = 5
===========================================
Explanation:
The given equation has slope 1/5. We can see that by comparing it to y = mx+b, with m as the slope.
Flip the fraction and the sign to go from 1/5 to -5/1 = -5. The perpendicular slope is -5. We can stop here since only choice B has such a slope.
---------------
If you're curious about finding the y intercept, then you would use m = -5 along with (x,y) = (2,-5) to find the value of b
y = mx+b
-5 = -5(2)+b
-5 = -10+b
-5+10 = -10+b+10 ... adding 10 to both sides
5 = b
b = 5 is the y intercept
So we have y = mx+b update to y = -5x+5 as the perpendicular line.
It's low ! Hope this helps:3
