Solve each of the following linear systems by eliminating
The regular price for an item that is on sale for $38.40 is $48.
A function takes in values, applies specific operations to them, and produces an output. The inverse function acts, agrees with the outcome, and returns to the initial function.
The output of a function is returned by the inverse function, which also returns the initial value.
Given the sale price of an item that has a regular price of R is,
S = R - 0.2R
the inverse function of R is
S = R(1 - 0.2)
S = R(0.8)
R = S/0.8
and the sale price is $38.40
regular price is,
R = S/0.8
R = 38.40/0.8
R = $48.
Hence the regular price is $48.

Answer:
R=48
Step-by-step explanation:
S=R(1-0.2) R = 38.40/.8
S=R(.8) R = 48
R=5/.8
Answer:
1000/2=500
Max=498000+500=498500
Min=498000-500=497,500

Answer: 14 inches
Step-by-step explanation:
Given the following :
James wants to cut a floor tile in the shape of a trapezium with the following dimension :
Top base = 12 inches
Bottom base = 16 inches
To obtain the medan, we take the average of the two bases :
(top base + bottom base) / 2
(12 inches + 16 inches) / 2
28 inches / 2
= 14 inches.
