Which equations are true for x = –2 and x = 2? Select two options x2 – 4 = 0 x2 = –4 3x2 + 12 = 0 4x2 = 16 2(x – 2)2 = 0
The equations that are true for x = –2 and x = 2 are:
x^2-4=0 and 4x^2 = 16
How can the equation be known?We can determine the equations that are true for x = –2 and x = 2 by testing the given options:
After testing the options option 1 ; x^2-4=0 putting x = 2 or -2 into the equation will give zero.
(2^)2-4=0
(-2)^2-4=0
Then option 4: 4x^2 = 16
4(2)^2 = 16
4(-2)^2 = 16

Find the length of line segment x.

B)

Answer:
x = 6
Step-by-step explanation:
4(x + 4) = 5(3 + 5) => Intersecting Secants Theorem
4(x + 4) = 5(8)
Open the bracket
4x + 16 = 40
Subtract 16 from each side
4x + 16 - 16 = 40 - 16
4x = 24
4x/4 = 24/4
x = 6
The length of the segment x is 6
The length of the segment x is calculated using the Intersecting Secants Theorem
This is represented as:
[tex]4(x + 4) = 5(3 + 5)[/tex]
Evaluate 3 + 5
[tex]4(x + 4) = 5(8)[/tex]
Open brackets
[tex]4x + 16 = 40[/tex]
Collect like terms
[tex]4x = 40 - 16[/tex]
Evaluate the like terms
[tex]4x = 24[/tex]
Divide both sides by 4
[tex]x = 6[/tex]
Hence, the length of the segment x is 6

How to calculate discount price in rupees?For example, you may want to calculate the sale price of a shirt that regularly costs Rs 1,000. If the shirt is 20% off, you must convert 20% to a decimal (20/100 = 0.2). You have Rs 1,000 * 0.2 = Rs 200. You then subtract the discount from the original price as Rs 1,000 – Rs 200 = Rs 800.Discount is the difference between the marked price (list price) and the selling price of an article. Therefore, the formula used to calculate discount is: Discount = List price - selling price.For example, $100 invested today in a savings scheme that offers a 10% interest rate will grow to $110. In other words, $110, which is the future value (FV), when discounted by the rate of 10% is worth $100 (present value) as of todayTo learn more about discount price refers to:

Which statement about the values 0.034 and 3.40 are true
Answer:
See Explanation
Step-by-step explanation:
This question requires options.
Since none is provided, I will give a general solution.
We have: 0.034 and 3.40
Required
The relationship between them
3.40 can be expressed as:
[tex]3.40 \to 0.034 * 100[/tex]
This means that 3.40 is 100 of 0.034
Similarly, 0.034 can be expressed as:
[tex]0.034 \to 3.40 * \frac{1}{100}[/tex]
This means that 0.034 is 1/100 of 3.40
the sum of two rational numbers is -2. if one of the numbers is -14/5 find the other number
The other number is 4/5
Step-by-step explanation:
let the number be x
if one of the numbers is -14/5
The sum of two rational numbers is -2.
Here, we get the equation
x + (-14/5) = -2
x - 14/5 = -2
x = 14/5 - 2
x = 14 - 2 × 5 ÷ 5
x = 14 - 10 ÷ 5
x = 4/5
Thus, The other number is 4/5
FOR VERIFICATION ONLY:x + (-14/5) = -2
4/5 + (-14/5) = -2
4/5 - 14/5 = -2
4 - 14/5 = -2
-10/5 = -2
-2 = -2
Hence, L.H.S = R.H.S

Answer:
y = 3x² + 5x + 1
x = -b±√b²-4ac/2a
a = 3, b = 5 c = 1
x = -5±√5²-4(3)(1)/2(3)
x = -5±√25-12/6
x = -5±√13/6
The number that belongs in the green box is -5.
Given:
Quadratic equation y = 3x² + 5x + 1 into the quadratic formula,
which is [tex]\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \][/tex], determine the values of a, b, and c from the given equation.
Comparing the equation y = 3x² + 5x + 1 with the standard quadratic form y = ax² + bx + c
a = 3
b = 5
c = 1
Now, substitute these values into the quadratic formula:
x = (-(5) ± √((5)² - 4(3)(1))) / (2(3))
x = (-5 ± √(25 - 12)) / (6)
x = (-5 ± √(13)) / 6
Therefore, the quadratic equation y = 3x² + 5x + 1 can be expressed in the quadratic formula as: x = (-5 ± √(13)) / 6
Thus, the number is -5.

DONE
To find the greatest common factor (GCF) between monomials, take each monomial and write it's prime factorization. Then, identify the factors common to each monomial and multiply those common factors together.
What is monomial?Monomial is defined as an expression that has a single non-zero term. It consists of different parts like the variable, the coefficient, and its degree. The variables in a monomial are the letters present in it. The coefficients are the numbers that are multiplied by the variables of the monomial. The degree of a monomial is the sum of the exponents of all the variables. Let us consider an expression 6xy2. The variables, the coefficient, and the degree of this monomial are shown in the table given below. Observe the table to learn the various parts of the monomial 6xy2.In algebra, a monomial is an expression that has a single term, with variables and a coefficient. For example, 2xy is a monomial since it is a single term, has two variables, and one coefficient. Monomials are the building blocks of polynomials and are called 'terms' when they are a part of larger polynomials. In other words, each term in a polynomial is a monomial.To learn more about coefficients refer to:

What are the mean absolute deviation and population standard deviation of this data set? Round to the nearest tenth if necessary. 2, 4, 6, 9, 14
Answer:
For a data set of N elements:
{x₁, x₂, ..., xₙ}
The mean is:
[tex]M = \frac{x_1 + x_2 + ... + x_n}{N}[/tex]
The mean absolute deviation is:
[tex]MAD = \frac{|x_1 - M| + ... + |x_n - M|}{N}[/tex]
And the population standard deviation is:
[tex]PSD = \frac{\sqrt{|x_1 - M|^2 + ... + |x_n - M|^2} }{\sqrt{N}}[/tex]
In this case, our set has 5 elements, and the set is:
{2, 4, 6, 9, 14}
The mean of this set is:
[tex]M = \frac{2 + 4 + 6 + 9 + 14}{5} = 7[/tex]
The mean absolute deviation is:
[tex]MAD = \frac{|2 - 7| + |4 - 7| + |6 - 7|+ |9 - 7| + |14 - 7| }{5} = 3.6[/tex]
And the population standard deviation is:
[tex]PSD = \sqrt{\frac{|2 - 7|^2 + |4 - 7|^2 + |6 - 7|^2+ |9 - 7|^2 + |14 - 7|^2 }{5}} = 4.2[/tex]
