Answer:
Step-by-step explanation:
Slope of a line passes through (a,b) and (c,d) =
In graph(below) given line is passing through (-2,-4) and (2,2) .
Slope of the given line passing through (-2,-4) and (2,2) =
Since parallel lines have equal slope . That means slope of the required line would be .
Equation of a line passing through (a,b) and has slope m is given by :_
(y-b)=m(x-a)
Then, Equation of a line passing through(-3, 1) and has slope = is given by
Required equation:
Answer:
(a) $248.285
(b) $249.441
(c) I will prefer to buy the television from online store.
Step-by-step explanation:
The manufacturing price of a television is $170.
(a) The online retailer charges a standard makeup of 27% and an additional 15% charge for shipping and tax.
Therefore the final price will be $
= $(170 × 1.27 × 1.15)
= $248.285
(b) Now, the superstore has makeup of 34% and then 9.5% charges for state tax.
So, the final price becomes $
= $(170 × 1.34 × 1.095)
= $249.441
(c) So, I will prefer to buy the television from the online store because the final price is less and also the shipping charges are included in the final price. (Answer)
