1. roots may be +/-1,2,3,6 and fractions
A root must be minus since if they were positive, the function would be >0.
-1 works by inspection, so (x+1) is a factor.
-1/1==6==11==6

can divide
1/1=0==-7===6
1---1-- -6===0
The factors are (x+1)(x^2+x-6)=(x-1)(x+3)(x-2)
roots are 1,2,-3
-
3.x^3+x^2-12x
factor out an x
x(x^2+x-12)=x(x+4)(x-3)
roots are 0, -4, 3
-
4.9x^3-7x+2
roots can be +/-1, and +/-2 along with (1/3) (2/3),(1/9), (2/9)
-1
(x+1) is a factor.
-1/9===0== -7===2
9----- -9===2====0
(x+1)(9x^2-9x+2)
factor the last with +/- 1, 2.
second factors by noting x^2-9x+18 factors Into (x-6)(x-3)
divide the constant by 9 and put the denominator in front
(3x-2)(3x-1)
so the roots are -1, (2/3), and (1/3)
-
5x³+4x²-31x+6, note: I will assume 31 x.
Roots include (1/5)(2/5)(3/5)(6/5) along with
+/- 1,2,3,6, and 1, -1 do not work by inspection
2/5===4=== -31===6
5------14---- -3===0
so (x-2)(5x^2+14x-3)
or (x-2)(5x-1)(x+3) are the factors
roots are 2, (1/5), -3

The table in question shows a proportional relationship between x and y, this shows that there is an independent and a dependent variable and their value compliments each other
This is further explained below.
What is the proportional relationship?Generally, The table in question demonstrates that there is a proportionate connection between x and y.
This indicates that there is both an independent and a dependent variable and that the values of both variables complement one another.
In conclusion, Relationships between two variables that are proportional occur when their ratios are equal.
Another way to consider them is that in a proportionate connection, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant.

A math test is worth 100 points. There are a total of 26 questions. There are equation questions that are worth 2 points each and vocabulary questions are 5 points each. Use a system of equations to solve for the number of equation questions and vocabulary questions on the math test.
Answer:
Let the number of equations be x and the number of vocabulary questions be y.
x + y = 26 (total num of questions)So, y = 26 - x (eliminate one variable to solve for one first)2x + 5y = 100 (total points)2x + 5 (26 - x) = 100 (substituting 26 - x in place of y)
2x + 130 - 5x = 100 (distributing the 5)-3x = -30x = 10
Since there are 10 equation questions, there must be 16 vocabulary questions to satisfy the total number of questions in the test

5 ft, 2 inch
The area of the rectangle with a base of 5ft and a height of 2 inches is: 120 square inches.
How to Determine the Area of a rectangle?The area of a rectangle is the product of the length of its base and its height.
Area of rectangle = (base)(height)
Given the parameters:
Length of the base of the rectangle = 5 ft
[Note: 1 ft = 12 inches]
Convert 5 feet to inches
5 feet = (5)(12) = 60 inches
Height of the rectangle = 2 inches

A linear equation could have more than one variable. If a variable's maximum power constantly equals one, an equation is considered to be linear.
Let us x ∝ y.
Following that, x = ky, where k is a constant or proportional.
When two variables that were in proportion are split, it will result in a constant proportional because k = x/y.

The resulting polynomial after subtracting will be -5x² +18x -9
In the given question, we have two polynomials. We have to Subtract (3x-3)² from 4x². Firstly we will have to calculate (3x-3)².
Calculating, (3x-3)²
=> (3x - 3)² = 9x² -18x +9
After evaluating (3x - 3)² we get 9x² -18x +9.
Subtracting 4x² by 9x² -18x +9 we get:
=> 4x² - (9x² -18x +9) => 4x² - 9x² +18x -9

Compound interest is interest calculated on the principal and the interest accrued in previous periods. Compound interest is interest based on principal and interest accumulated over a period of time.If we specifically state that the quantity in question is "continuously composed", we must use the continuous constitutive formula which is given by [tex]A=Pe^{rt}[/tex] .....
