Answer:
5x + 3y = 12
Step-by-step explanation:
We are given the line 5x + 3y = 6 and are to find the equation of a new line that is parallel to this one and goes through (3, -1).
Parallel lines have the same slope. The slope of the given line is determined by the coefficients 5 and 3 visible above. Therefore, the form of the equation of the new line is 5x + 3y = C, where we must determine the value of C.
Substitute 3 for x and -1 for y in 5x + 3y = C, obtaining: 5(3) + 3(-1) = C. Then 15 - 3 = 12 is the constant value, and the equation of the 'new line' is
5x + 3y = 12
Original price = $33,750
Marked down price = $29,700
Amount of decrease = $33,750 - $29,700
= $3050
What you are trying to find is the percentage of "amount of decrease" as compared to "original price" ("original price" will be your 100%).
Amount of decrease ÷ original price = $3050 ÷ $33,750 <This will be your ratio>
To find percentage decrease, $3050 ÷ $33,750 × 100 = 9.04% (rounded off to 3 significant places)
Hope this helps! :)
1. 13
2. 29.77
3. 21.7
Hope this helps:)
Btw I rounded the 2 and 3
If you can please post a trinomial, I would be happy to assist you.
