ok so at first if u have fractions like the first follow my instruction:
1st: u have 2/3---1/2, u will multiply 3 by 1 and 2 by 2 so u will get 6 and 4
but remember that 2/3 and 1/2 u cris cross it the left one comes first like 6 then 4 so it could balance and do the rest of the fractions like that.
2nd: if u have decimal u will check the number after the decimal but if the are the same u will compare the numbers before the decimal.

The graph shows the relationship between the number of cups of flour and the number of cookies made. Write an equation for the proportional relationship.
Answers
The equation for the proportional relationship is 16x-y=0 .
The equation of the line passing through the two points (a,b) and (c,d) is given by
(y-b) = m(x-a), where m is the slope .
In the question ,
Given in the graph that
x represents the number of cups of flour and y represents the number of cookies made .
From the graph we can see that
when 6 cups of flower is used , 96 cookies are made
So, the point on the line is (6,96),
when 12 cups of flower is used , 192 cookies are made
So, the point on the line is (12,192)
hence the line passes through the two points (6,96) and (12,192).
So the slope of the line is
m=(192-96)/(12-6)
m= 96/6
m=16
Substituting the values of a,b, c,d and m in the equation of line formula ,we get
y-96=16(x-6)
y-96 = 16x - 96
16x-y=96-96
16x-y=0
Therefore , The equation for the proportional relationship is 16x-y=0.

The simplified form is 3/4( 2s-1).
The problem we dealing with here is related to factors of linear polynomial, where a linear polynomial is characterized as any polynomial expressed in the form of a condition of p(x) = ax + b, where a and b are real numbers and a ≠ 0. In a linear polynomial, the degree of the variable is rise to 1 i.e, the highest type of the variable is one, whereas a factor of polynomial P(x) is any polynomial that divides equitably into P(x). The factorization of a polynomial is its representation as a product of its variables.

Answers
The first term of the series such that the sum of the first three terms of the geometric series is 171 is equal to 81.
What is the first term of a geometric series?
In this problem we find the sum of three consecutive elements of a geometric series. A geometric series is a set of elements generated by a discrete exponential expression of the form:
y = a · rⁿ ⁻ ¹
Where:
a - First term of the series.r - Common ration - Index fo the element.According to the statement, we find the following expression:
a · (2 / 3)² + a · (2 / 3)¹ + a · (2 / 3)⁰ = 171
(4 / 9) · a + (2 / 3) · a + a = 171
(19 / 9) · a = 171
a = 81
Then, the first term of the series is:
y = 81 · (2 / 3)¹ ⁻ ¹
y = 81

The interval that describes where the graph of this function is negative is: C. 2 < x < ∞
What is a graph?A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
Generally speaking, a function is typically used for mapping an input variable to an output variable. In Mathematics, the value of y on the y-axis of a graph must be less than 0 (x < 0) for the graph of any function to be negative.
By critically observing the graph of this function, we can logically deduce that at point x = 2 is where the value of y becomes less than 0 (x < 0) and continues to infinity. Therefore, the graph of this function is negative is at an interval of 2 < x < ∞.

5. A man's taxable income is $35 200. He pays income tax at the rate of 25%. The amount of income tax payable is
Answers
If a man's taxable income is $35200 and he pays income tax rate of 25%, the amount of income tax payable is $8800
The man's taxable income = $35200
The income tax rate = 25%
The percentage is the hundredth part of any number.
The amount of income tax payable = The man's taxable income ×(The income tax rate/100)
Substitute the values in the equation
The amount of income tax payable = 35200×(25/100)
= 35200×0.25
