Calculate the % loss
Cost price of an article =$28
Selling price of the article=$21
The loss in percentage is 25%.
Given that,
Cost price of an article = $28
Selling price of the article = $21
We know that,
A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Now loss can be calculated by subtracting selling price from cost price,
Therefore,
28 - 21 = 7
Hence there are loss of $7 in business,
Now to calculate percentage loss,
Divide loss by cost price then multiply with 100,
Then,
⇒ (7/28)x100
⇒ 25%

Does -a ? = (-a)?? Explain why or why not.
Explanation:
Always remember that variables have coefficients (x is the same as 1·x or 1x).
Raising a base to either an odd or even exponent has particular rules when it comes to signs:
If you raise -a² = -a² because a has a coefficient of - 1. This implies that -a² = -1a². Now, raising -a³ (odd exponent) still results in -a³ because you're only raising the base, a, to its exponent, and it doesn't include its coefficient of -1. Hence, -a³ = -1a³ = -a³.Also, (-a²) = -a² because once again, you're only raising the base, a, and not its coefficient (even if both are inside the parenthesis).It will be different if the base is raised as follows:
(-a)² = a² because the coefficient, -1, is included within the parenthesis. It is the same as (-1a)² = 1a² or a².(-a)³ = -a³ or -1a³ because it is an odd exponent, and if you raise a negative base to an odd exponent results in a negative value of the base.The key is that the exponent outside the parenthesis will affect both the coefficient and its base, such as (-a)².
Hope this makes complete sense.

The area of a rectangle is 33 m”, and the length of the rectangle is 5 m less than double the width. Find the dimensions of the
• rectangle
Answer:
Width: 5:5
Length: 6
Area: (6) (5.5 = 33m^2
Step-by-step explanation:
Width: x
Length: 2x - 5
(2x-5)(x) = 33
2x^2 - 5x - 33 = 0
(2x - 11) (x + 3) = 0
2x - 11 = 0
x = 11/2 = 5.5
x + 3 = 0
x = -3
[(2*5.5)-5](5.5) = 33

The table below represents a linear function f(x) and the equation represents a function g(x):
x f(x)

0 -1
1 7
g(x) = 3x-2
Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).
Part B: Which function has a greater y-intercept? Justify your answer.
Please hurry as I only have a few hours left too turn in :) Thank you.
Answer:
Use 2 points from he table to find the slope of f(x):
(0, -1) and (1, 7)The slope is:
m = (7 - (-1))/1 = 8The y - intercept is b = -1 according to point (0, -1).
Part AThe lines are:
f(x) = 8x - 1g(x) = 3x - 2The f(x) has greater slope since 8 > 3 and greater y-intercept since -1 > - 2.
Part BSee above

2. Railyn is saving for a laptop computer. She already has
$800 saved and plans to save $50 a week from her baby
sitting money. If the laptop she wants costs $1,150, how
many weeks will it take her to save enough to buy it?
a. Define the variable and represent the situation with
an equation.
x = number of weeks which is some positive whole number
50x = amount saved after x weeks, when saving $50 per week
50x+800 = add on the 800 she already has
The expression 50x+800 is the total money saved. We set this equal to the 1150 to set up the equation we're after
