y = 2x
This is a positive line that increases from left to right, because the number 2 of the equation is positive.
So from the graphs that you send me, the right answer is the second one, it is an increasing line.
A graph increases from left to rigth if it goes up

Sale tax rate = 6.85%
To calculate the sale tax on a $14,000 Car, multiply 14,000 by the sale tax rate in decimal form ( divided by 100)
14,000 x (6.85/100) = 14,000 x 0.0685= $959
To find the final cost, add the sale tax amount to the price:
14,000 + 959 = $14,959

Antonio's plan is
[tex]3(0.75m+10)+2.50m-15[/tex]Brielle's plan is
[tex]2(1.50m+12)+m-4[/tex]Then, we express both expressions as equivalent to finding the number of minutes needed to cost the same.
[tex]3(0.75m+10)+2.50m-15=2(1.50m+12)+m-4[/tex]First, we use the distributive property.
[tex]2.25m+30+2.50m-15=3m+24+m-4[/tex]Then, we reduce like terms.

What is a expression? What is a mathematical equation? What is Equation Modelling?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

kurtosis is a measure of multiple choice the normality of a distribution. how fat the tails of a distribution are.
Answers
The normality of a distribution as well as how fateful its tails are Kurtosis is a test for a distribution's normality that focuses on the size of the tails.
Kurtosis is a metric that indicates how heavy-tailed or light-tailed the data are in comparison to a normal distribution. In other words, data sets with a high kurtosis tend to have large outliers or heavy tails. Data sets with low kurtosis frequently lack outliers and have light tails. The worst-case scenario would be a uniform distribution.
Kurtosis is three and skewness is zero for the normal distribution. The test is based on how much the data's skewness deviates from zero and how far its kurtosis deviates from three. When the p-value is less than or equal to 0.05, the test rejects the normality hypothesis.

The System of PolynomialsYou are aware of the different types of numbers: natural numbers, integers, rational numbers, and real numbers. Now you will work with a property of the number system called the closure property. A set of numbers is closed for a specific mathematical operation if you can perform the operation on any two elements in the set and always get a result that is an element of the set.Consider the set of natural numbers. When you add two natural numbers, you will always get a natural number. For example, 3 + 4 = 7. So, the set of natural numbers is said to be closed under the operation of addition.Similarly, adding two integers or two rational numbers or two real numbers always produces an integer, or rational number, or a real number, respectively. So, all the systems of numbers are closed under the operation of addition.Think of polynomials as a system. For each of the following operations, determine whether the system is closed under the operation. In each case, explain why it is closed or provide an example showing that it isn’t.1. AdditionType your response here:2. SubtractionType your response here:3. MultiplicationType your response here:4. DivisionType your response here:
Answers
Polynomials are closed under the operation of addition, subtraction, and multiplication only. Here's why:
1. Addition: (Closed)
Reason: Say we have two polynomials: (x⁴ + 2x³ - 4) and (3x³ - 2x² + 6x). If we add these two polynomials, (x⁴ + 2x³ - 4) + (3x³ - 2x² + 6x), it will result to x⁴ + 5x³ - 2x² + 6x - 4 which is also a polynomial.
When adding polynomials, the variables and the exponents don't change. This guarantees that the sum of these variables with exponents will always be a polynomial.
2. Subtraction: (Closed)
Reason: Say we have two polynomials: (x⁴ + 2x³ - 4) and (3x³ - 2x² + 6x). If we subtract these two polynomials, (x⁴ + 2x³ - 4) - (3x³ - 2x² + 6x), it will result to x⁴ - x³ + 2x² - 6x - 4 which is also a polynomial.
When subtracting polynomials, the variables, and the exponents don't change. This guarantees that the difference of these variables with exponents will always be a polynomial.
3. Multiplication: (Closed)
Reason: Say we have two polynomials (x + 2) and (x - 4). If we multiply these two polynomials, (x + 2)(x - 4), it will result in x² - 2x - 8, which is also a polynomial.
When multiplying polynomials, the variables do not change but the exponents will be added to each other. In this case, we can guarantee that the new exponents will be positive whole numbers still and this guarantees that the answer will be a polynomial.
4. Division: (Not closed)
Reason: When dividing polynomials, exponents are being subtracted from each other, therefore, we might have a result of a negative exponent. Negative exponents are not allowed in a polynomial. Example, say we have two polynomials (x²) and (x⁴), if we divide (x²) by (x⁴), the resulting value would be:
[tex]\frac{x^2}{x^4}=x^{-2}[/tex]The resulting value is x to the power of negative 2, and is not a polynomial.
