Answer:
Tn = 17-6n
Step-by-step explanation:
d = 5-11 = -6
Tn = a + (n-1)d = 11 + (n-1)×-6
= 11 -6n +6 = 17-6n
Answer:
D. 
Step-by-step explanation:
The point-slope form of a line is given by:

The line given to us has equation;
.
The slope of this line is -4. The of the line perpendicular to this line is the negative reciprocal of the slope of the given line.
Our slope of interest is therefore; 
Since the point goes through (-2,7), we have
.
We plug in the slope and the point into the point-slope formula to obain;

The required equation is:

You need to subtract 16.2 from 1.6 which is (-14.6) then divde by 8 on both sides leaving you with n=-1.825
90 divided by 5 would be 18, so you want to do 18 times 2 I'm pretty sure, so it will be 36 minutes.
Answer:
1. C 2. 4.95
Step-by-step explanation:
1. Car payments are typically set so that the payments are equal (with the possible exception of the very last payment--sometimes called a balloon payment).
2. "Difference" implies a subtraction: 7.75 - 2.8 = 4.95. That is not among the answers offered; could answe B be a typo?
