Answer:
Associative Property
Commutative Property
Distributive Property
Identity Property
Step-by-step EXPLANATION
ASSOCIATIVE PROPERTY
In this property, irrespective of the regrouping between a number and the addent within a bracket, the sum, value does not change.
For example:
(A + B) + C = A + ( B + C)
COMMUTATIVE PROPERTY
In commutative Property, you will always get thesame results after changing the order or position of the addent.
For example:
A + B = A + B
Also,
A + B = B + A
DISTRIBUTIVE PROPERTY
Basically here, please note that, the sum (addition) of two numbers times a Third one is always equal to the sum of these numbers times the third one.
For Example:
A x (B + C) = AB + AC
IDENTITY PROPERTY
This property is the easiest of all, it simply says that "Add a number to Zero must always be that number".
For example:
A + 0 = A
B + 0 = B
C + 0 = C

The advantage of using a table to determine the equivalent ratio is that, it easier to determine the unknown ratio.
The advantage of using a graph to determine the equivalent ratio is that, it helps to determine the exact value of the unknown ratio.
The use of table to find equivalent ratio makes it easier to determine the unknown ratio. The unknown ratio can easily be determined using interpolation method, this method gives the approximate value of the unknown ratio.
The use of graph to find equivalent ratio helps to determine the exact value of the unknown ratio. This method gives the exact value of the unknown ratio.
The use of table is better because it minimizes error from tracing the values from the graph.

Answer:
y = x² - 3x - 28
Step-by-step explanation:
given a parabola with x- intercepts x = a and x = b , then
(x - a) and (x - b) are the corresponding factors and the equation is the product of its factors
y = (x - a)(x - b)
here the x- intercepts are x = - 4 and x = 7 , then the factors are
(x - (- 4)) and (x - 7) , that is (x + 4) and (x - 7) , then
y = (x + 4)(x - 7) ← expand using FOIL , then
y = x² - 3x - 28 ← in standard form
The original price of the sweater is $80 which is 100% of the price.
If the price is reduced by 25%, then the new price is 75% of the original price since 100% - 25% = 75%.
Now we need to find 75% of $80.
To find a percent of a number, multiply the percent by the number.
To convert a percent into a decimal, divide the percent by 100 which is the same as moving the decimal point two places to the left.
Here's how to change 75% into a decimal.
75% = 75/100 = 0.75
Here's how you calculate 75% of $80.
75% of $80 =
= 75% * 80
= 0.75 * $80
= $60
Answer: The sale price is $60.
