Answer:
Equation: -5 <3× -8
+8. +8
3 <3x
_ _
3. 3
Answer: 1 = X
Step-by-step explanation:
Equation: -5 <3× -8
First Step: You must add 8 to -8 and move it to both sides. The reason why we do this is because on the left side we have 1 number and on the right side we have 2 numbers. We see that the right side has more numbers than the left, so we must move the -8 turning it to a positive 8 (8-8 cancels each other making 0) and adding the +8 in -8 to -5 as well, since we're adding to both sides.
Second Step: Since we added 8 to -5, it equals 3 now 8-5=3. Changing the equation to 3 <3x. Now we have to divide 3 to both sides as well, because we want the x to be by itself. So, 3 ÷ 3 = 1 and 3x ÷ 3 = x
Results: After our extraordinary calculations we recieve

The value of y in the equation 1/2 = 1/4y + 1/8y when solved is y = 4/3 .
A linear equation in one variable is defined as an equality between two expression either or both containing the variable .
A linear polynomial over a field, from which the coefficients are taken, can be reduced to a linear equation by equating it to zero.There is only one answer when there is only one variable. The term "linear equation" frequently alludes indirectly to this specific situation, in which the variable is appropriately referred to as the "unknown."When we say we've solved an equation, we mean we've found the value of the variable that, if we plugged it into the equation, would make it true or balanced.The given expression can be written a linear equation of the form :
1/2 = 1/4y + 1/8y
Simplifying the equation we get :
y = 4 / 3

The answer of the given question of radicals is -1.
What is radicals?
A surd or radical is an unresolved root, particularly one that employs the radical symbol. A radical expression is any expression that contains a radical, whether it is a square root, a cube root, or a higher root, while an algebraic expression is any statement that does not contain any transcendental functions or transcendental numbers. The root test is used to determine the radius of convergence of a power series. The nth roots of 1 are known as roots of unity, and they play an important role in many areas of mathematics, including number theory, equation theory, and the Fourier transform.
Given, ∛-1

B) f(x)=3x^2−x+2
C) f(x)=3x^2+2x−1
D) f(x)=3x^2−2x−1
The quadratic equation in standard form is y = 3 · x² + 2 · x - 1. (Correct choice: C)
How to derive the quadratic equation associated with a set of three points
In accordance with the fundamental theorem of algebra, a quadratic function can be found by knowing three distinct points. Quadratic functions are polynomials of the form, known as standard form:
y = a · x² + b · x + c
Where a, b, c are real coefficients.
If we know that (x₁, y₁) = (- 3, 20), (x₂, y₂) = (0, - 1) and (x₃, y₃) = (2, 15), then the coefficients of the polynomial are found by numerical methods:
9 · a - 3 · b + c = 20
c = - 1
4 · a + 2 · b + c = 15
The solution to the system of linear equations is (a, b, c) = (3, 2, - 1). The equation is y = 3 · x² + 2 · x - 1.

Anupa's favorite fraction is equal to $\frac{5}{3}$. The sum of the numerator and denominator of Anupa's favorite fraction is $160$. What is the difference between the numerator and denominator of Anupa's favorite fraction?
The difference between the numerator and denominator of the fraction parameters is 40
How to determine the difference between the fraction parameters?From the question, the fraction is given as
5/3
The above fraction can be represented as
5x/3x
This is so because of the following equation
5x/3x = 5/3
The above is calculated by dividing the numerator and the denominator by the common factor x
Solving further, we have
Sum of the numerator and denominator = 160
This means that
5x + 3x = 160
Evaluate the sum in the above equation
So, we have
8x = 160
Divide both sides of the fraction by 8
So, we have
x = 20
The required difference is represented as
Difference = 5x - 3x
Evaluate
Difference = 2x
Substitute x = 20 in Difference = 2x
So, we have
Difference = 2 x 20
Evaluate
Difference = 40
Hence, the difference between the fraction parameters is 40

To solve the inequality given by -n/7 ≤ 14 , -7 should be multiplied to both sides of the inequality .
Any monotonically rising function can, by definition, be applied to both sides of an inequality without changing their connection to one another (provided that both expressions are in the domain of that function).
If a monotonically falling function were applied to both sides of an inequality, the inequality relation would be reversed.The rules for the additive inverse and the multiplicative inverse for positive numbers serve as illustrations of the use of a monotonically declining function.If the function is strictly monotonic and the inequality is strict (a b, a > b), the inequality remains strict.If only one of these conditions is fulfilled, the resulting inequality is not strict. The conditions for both additive and multiplicative inverses really serve as a demonstration that a strictly monotonically dropping function is being applied.The inequality is -n/7 = 14
or, -n ≤ 14 × 7
or, -n ≤ 98
or, n ≥ -98
Therefore the first step is solve the inequality is to multiply both sides by 7.

let ???? represent the difference between the number of heads and the number of tails obtained when a coin is tossed ???? times. what are the possible values of ?????
The possible values of X are that if n is even X can takes even integers from [-n, n], and if n is odd, X can takes odd integers from [-n, n]
To solve this question, we can use X to represents the difference between the number of heads and the number of tails obtained when a coin is tossed X times, the possible values of X are now obtained below:
Let H be the no. of heads and T be the no. of tails, since the coin is tossed n times, we have:
H+T=n
now, X = H-T ,
X=H-(n-H)
X=2H-n
Now,
H takes values {0,1,2,3 ......,n-2, n-1,n}
2H takes values {0,2,4,6,.....,2n-4,2n-2,2n}
2H - n takes values {-n,-(n-2),-(n-4), -(n-6),.............,n-4, n-2,n}
X takes values {-n,-(n-2), -(n-4),-(n-6),.............,n-4, n-2, n}
therefore, if n is even X can takes even integers from [-n, n]
and, if n is odd, X can takes odd integers from [-n, n]

A toy rocket is launched from a 2.1 m high platform in such a way that its height, h (in meters), after t seconds is given by the
equation h = -4.9t² + 14.0t+2.1. How long will it take for the rocket to hit the ground?
Answer:
3 seconds
Step-by-step explanation:
The height of the rocket when it hits the ground will be zero meters.
Therefore, set the equation to zero and solve for t by using the quadratic formula.
Quadratic Formula
[tex]x=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}\quad\textsf{when }\:ax^2+bx+c=0[/tex]
Given equation:
[tex]-4.9t^2+14t+2.1=0[/tex]
Therefore:
[tex]a=-4.9, \quad b=14, \quad c=2.1[/tex]
Substitute the values into the quadratic formula:
[tex]\implies t=\dfrac{-14 \pm \sqrt{14^2-4(-4.9)(2.1)}}{2(-4.9)}[/tex]
[tex]\implies t=\dfrac{-14 \pm \sqrt{196+41.16}}{-9.8}[/tex]
[tex]\implies t=\dfrac{-14 \pm \sqrt{237.16}}{-9.8}[/tex]
[tex]\implies t=\dfrac{-14 \pm15.4}{-9.8}[/tex]
Therefore:
[tex]\implies t=\dfrac{-14 +15.4}{-9.8}=\dfrac{1.4}{-9.8}=-\dfrac{1}{7}[/tex]
[tex]\implies t=\dfrac{-14-15.4}{-9.8}=\dfrac{-29.4}{-9.8}=3[/tex]
As time is positive, t = 3 s only.
Therefore, it will take 3 seconds for the rocket to hit the ground.

A. The lines with equation 3x - 4y = 6 and 3y = -4x + 9 are perpendicular
B. The lines with equation y = 1⁄2x - 7 and 6x - 12y = 24 are parallel
How do I determine if the lines are parallel or perpendicular?From the equation of lines, we can detect if they are parallel or perpendicular as follow:
Parallel lines have the same slope (or gradient). Thus, m₁ = m₂Perpendicular lines have slope that have the following property: m₁ × m₂= -1With the above information, we can obatin the answer to the questions. Details below
For question A.
We shall determine the slope of each line. This can be obtained as follow:
3x - 4y = 6
Rearrange
4y = 3x - 6
y = 3/4x - 6/4
Comparing y = 3/4x - 6/4 with y = mx + c, the slope is 3/4
3y = -4x + 9
y = -4/3x + 9/3
Comparing y = -4/3x + 9/3 with y = mx + c, the slope is -4/3
Slope (m₁) of 3x - 4y = 6 is 3/4Slope (m₂) of 3y = -4x + 9 is -4/3m₁ × m₂
3/4 × -4/3 = -1
Thus, we can say: 3x - 4y = 6 and 3y = -4x + 9 are perpendicular
For question B.
We shall determine the slope of each line. This can be obtained as follow:
y = 1/2x - 7
Comparing y = 1/2x - 7 with y = mx + c, the slope is 1/2
6x - 12y = 24
Rearrange
12y = 6x - 24
y = 6/12x - 24/2
y = 1/2x - 12
Comparing y = 1/2x - 12 with y = mx + c, the slope is 1/2
Slope (m₁) of y = 1/2x - 7 is 1/2Slope (m₂) of 6x - 12y = 24 is 1/2m₁ = m₂
Thus, we can say: y = 1/2x - 7 and 6x - 12y = 24 are parallel
