Let's solve for f.
y=f−1x
Step 1: Flip the equation.
f−x=y
Step 2: Add x to both sides.
f−x+x=y+x
f=x+y
Answer:
f=x+y
Answer:
Step-by-step explanation:
marked down by 1/4 of the original price.
let x represent original price
original price - 1/4 of original price = sales price
x - 1/4x = 128
4/4x - 1/4x = 128
3/4x = 128
x = 128/(3/4)
x = 128 * 4/3
x = 512/3
x = 170.666 rounds to 170.67 <== original price
==============================
I hope I am understanding this one correctly...
let x = price the store paid
x + 1/2x = 170.67
2/2x + 1/2x = 170.67
3/2x = 170.67
x = 170.67 / (3/2)
x = 170.67 * 2/3
x = 341.34/3
x = 113.78 <=== what the store paid
===========================
the difference between the discount price..I am assuming this is the $ 128 from part A.....and what the store paid....113.78...from part B..
128 - 113.78 = $ 14.22 <==
I am not completely sure about B and C......B confused me.....and if B is wrong, so is C.
C is the correct answer.

Answer: 24 square meters</h3>
The notation "m^2" is a shorthand way of saying "square meters".
Chances are you'll simply type in the number and leave out the units, as that's already taken care of.
==========================================================
Work Shown:
area = base*height
area = 8*3
area = 24 square meters
---------
Explanation:
We simply multiply the base 8 and height 3 and that's our answer. It's not a trick question even if it might seem like it.
The side that's 7 meters long is never used. The base and height are always perpendicular to one another, which means that they form a right angle (aka 90 degree angle).
The area formula of a parallelogram and rectangle are the same. We can think of a non-rectangular parallelogram as a slanted rectangle in a sense. Imagine you had stacks of blocks to form a rectangle. Now imagine nudging that stack slightly to one side. The blocks themselves don't change, so the area of one wall doesn't change. All that's changed is the shape.
