Answer:
The equation of the line y= 5x+1. Line that is parallel to the function given should have the same slope as the equation which is 5. We use the point-slope form in order to find the second equation that contains the point (4,5).
y - 5 = 5(x-4)
y = 5x - 20 +5
y≈ 5x -15
Answer:
44.2%
Step-by-step explanation:
Rate of discount = (difference in prices / original price) x 100
Difference in price = $1299 - $725 = $574
Original price = $1299
($574 / $1299) x 100 = 44.187837%
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
the hundredth figure is 8, which is greater than 5. 1 would be added to the tenth figure.
So it becomes 44.2%
