The angel L in the triangle JKL is measured as 52 degree.
What is triangle?
A triangle in geometry is a three-sided polygon with three edges and three vertices. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic. This characteristic is known as the triangle's angle sum property.
Given in the question,
∠J = (8x+6)°
∠K = (2x+2)°
∠L = (4x+4)°
We know that, the sum of the all angles in triangle is 180°
So, in triangle JKL
∠J + ∠K + ∠L = 180
Putting the values from the question. we get,
(8x+6) + (2x+2) + (4x+4) = 180
14x + 12 = 180
(180 - 12)/14 = x
x = 12
Putting the value of x in given value of angle L.
∠L = 4x+4
∠L = 4(12)+4
∠L = 48 + 4
∠L = 52°
Hence the angle L is measured as 52 degrees.

He following cards are dealt to three people at random, so that everyone gets the same number of cards. what is the probability that everyone gets a red card?
The probability that everyone will get a red card is 0.5.
What probability exactly is?Probability is a branch of mathematics that deals with numerical representations of the probability that an event will happen or that a statement is true.The probability of an event is a number between 0 and 1, with 0 roughly denoting impossibility and 1 denoting certainty.The probability is the likelihood that something will happen, to put it simply.The likelihood or likelihood of various outcomes can be discussed when we don't know how an event will turn out.The study of events that fit into a probability distribution is known as statistics.So, the probability that everyone gets a red card:
Probability formula: P(E) = Favourable events/Total number of eventsAs cards are distributed to 3 people, divide both favorable events and total events by 3.Then,
P(E) = Favourable events/Total number of eventsP(E) = (26/3)/(52/3)P(E) = 26/3 × 3/52P(E) = 26/52P(E) = 0.5Therefore, the probability that everyone will get a red card is 0.5.

Two angles form a linear pair. The measure of one angle is z and the measure of the other angle is 2.4 times z plus 10°. Find the measure of each angle.
Two angles form a linear pair.
so, the sum of the angles are 180
the measure of the angles are z and (2.4 * z + 10)
so,
z + (2.4 * z + 10) = 180
solve for z
so,
z + 2.4 * z + 10 = 180
3.4 z = 180 - 10
3.4 * z = 170
divide both sides by 3.4
so, z = 170/3.4 = 50
so, the angles are 50 and 130

4 × logx -(2 × logv + 3 × logy)
Simplifying the given logarithmic equation, the expression is obtained as log([tex]\frac{x^{4} }{v^{2} y^{3} }[/tex]).
The objective is to find the resultant expression for 4 × logx -(2 × logv + 3 × logy)
According to logarithmic results,
The product of an integer constant and a logarithm term of a number is equivalent to the logarithm of the number raised to the power of the particular integer constant.
That is, b × log(a) = log([tex]a^{b}[/tex])
Hence, 4 × log(x) = log([tex]x^{4}[/tex]),
2 × log(v) = log([tex]v^{2}[/tex])
and, 3 × log(y) = log([tex]y^{3}[/tex])
So, the equation can be rewritten as log([tex]x^{4}[/tex]) - (log([tex]v^{2}[/tex]) + log([tex]y^{3}[/tex]))
The sum of the logarithms of two numbers is equivalent to the logarithm of their product.
That is, log(a) + log(b) = log(a×b)
Hence, log([tex]v^{2}[/tex]) + log([tex]y^{3}[/tex]) = log([tex]v^{2}[/tex][tex]y^{3}[/tex])
So, the equation can be rewritten as log([tex]x^{4}[/tex]) - log([tex]v^{2}[/tex][tex]y^{3}[/tex])
The difference in the logarithms of two numbers is equivalent to the logarithm of their fraction.
That is, log(a) - log(b) = log(a÷b)
Hence, log([tex]x^{4}[/tex]) - log([tex]v^{2}[/tex][tex]y^{3}[/tex]) = log([tex]\frac{x^{4} }{v^{2} y^{3} }[/tex])

The expression is equivalent to option A, 8x[tex]\sqrt[6]{x}[/tex].
Option A is correct
How do expressions work?Variables, constants, and mathematical operators make up an expression, which is a mathematical statement.
How can one locate equivalent expressions?Add any like terms together, combining x-terms with x-terms and constants with constants, on either side of the equation. The x-term is typically put before constants when arranging the terms in the same sequence. It is said that two expressions are equivalent if every phrase in them is the same.
The expression is 2[tex]\sqrt[3]{x^2}[/tex]
The expression can be simplified as
= 2.4[tex]x^{2/3}[/tex][tex]x^{1/2}[/tex]
= 8[tex]x^{7/6}[/tex]
= 8x[tex]x^{1/6}[/tex]

Write an equation for the line that is
perpendicular to the line y = 4x + 9
and goes through the point (2, 8).
Answer:
[tex]\sf y =\dfrac{-1}{4}x+\dfrac{17}{2}[/tex]
Step-by-step explanation:
Equation of the line: y =mx + bwhere m is slope and b is y-intercept.
y = 4x + 9
Slope = m₁ = 4
[tex]\sf \text{Slope of the perpendicular line = $\dfrac{-1}{m_1}$}[/tex]
[tex]\sf \boxed{m = \dfrac{-1}{4}}[/tex]
[tex]\sf y =\dfrac{-1}{4}x +b[/tex]
The point (2,8) passes through the line. Substitute in the above equation to find 'b'.
[tex]\sf 8 = \dfrac{-1}{4}*2+b\\\\\\ 8 = \dfrac{-1}{2}+b\\\\[/tex]
[tex]\sf 8+\dfrac{1}{2}=b\\\\ \dfrac{16}{2}+\dfrac{1}{2}=b\\\\ \boxed{b=\dfrac{17}{2}}[/tex]
Equation of the line:
[tex]\sf y =\dfrac{-1}{4}x + \dfrac{17}{2}[/tex]

The quadratic equation that Olivia is solving is y = x² + 4x + 6
Any expression that can be changed into standard form, such as the ones below, is considered to be a quadratic equation in algebra:
y = ax² + bx +c
With a = 0 (and b = 0), the equation is linear rather than quadratic since the ax² term is omitted, and x symbolizes an unknown whereas a, b, and c denote known quantities.The quadratic coefficient, linear coefficient, and constant or free term are the three coefficients of an equation, indicated by the numbers a, b, and c, respectively.The values of x that satisfy the equation are represented by the roots or zeros of the equation on the left side of the equation.We know that the quadratic formula to solve a quadratic equation is:[tex]{\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}}[/tex]Now from the given step and by using the quadratic formula we can ascertain that the values of a ,b and c are 1 ,4 and 6 respectively.
hence the quadratic equation is y = x² + 4x + 6.

Please help me solve this algebra problem on my homework
We need to determine a few characteristics of the following linear equation:
[tex]y-5=-\frac{1}{2}(x-2)[/tex]The first step we need to take is to isolate the "y" variable on the left side.
[tex]\begin{gathered} y=\frac{-1}{2}(x-2)+5 \\ y=\frac{-1}{2}\cdot x+1+5 \\ y=\frac{-1}{2}\cdot x+6 \end{gathered}[/tex]Now we need to analyze this function and provide the necessary characteristics.
First is the Domain. The Domain of a function is the group of all numbers that can be used as an input (x), in this case the Domain is the whole Real group.
Second is the Range, which is the group of numbers that can be the output of the function (y), for this case we also have the whole Real group as Range.
Then we need to find the "Zero". Which is the value at which the function crosses the x-axis, to calculate it we must make "y=0" and solve for x.
[tex]\begin{gathered} 0=\frac{-x}{2}+6 \\ \frac{x}{2}=6 \\ x=12 \end{gathered}[/tex]The zero is equal to 12.
The slope of the function is the number multiplying "x", in this case it is -1/2.
The slope is negative, decrescent.
To find the value of f(8), we need to replace x by 8 and solve for y.
[tex]\begin{gathered} f(8)=\frac{-8}{2}+6 \\ f(8)=-4+6=2 \end{gathered}[/tex]The value of f(8) = 2.
To determine the value of x where f(x) is equal to 5, we need to replace f(x) by 5 and solve for x.
[tex]\begin{gathered} 5=\frac{-x}{2}+6 \\ \frac{-x}{2}=5-6 \\ \frac{-x}{2}=-1 \\ -x=-2 \\ x=2 \end{gathered}[/tex]The value of x for which f(x) is equal to 5, is 2.
Now we need to graph the equation, for that we have to use two of the points we found before, we will use (8, 2) and (2,5). We need to mark these points at the coordinate plane and draw a line between them:
Identify any solutions to the system shown here
2x+3y>=6
3x=2y<=6
(1.5, 1)
(0.5, 2)
(–1, 2.5)
(–2, 4)
For the given equation 2x+3y≥6 and 3x=2y≤6, the solution is (1.5, 1). Option A is correct.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that,
3x=2y<=6
3x =2y
y=1.5x
3x≤6
x≤2
2y≤6
y≤3
As a result, we found that y is 1.5 times x, the value of x should be less than 2, and y should be less than 3.
We analyze each option one by one we obtained the correct values is,
(y,x) = (1.5, 1)
The values follow all the obtained condition
Thus, for the given equation 2x+3y≥6 and 3x=2y≤6 the solution is (1.5, 1). Option A is correct.

except the greater than symbol has a line under. Graph each inequality and write the solution set using both set-builder notation and interval notation.
The solution set of the inequality x ≥ - 4 using set builder notation and interval notation is {x | x ∈ Z, - 4 ≤ x ≤ ∞ } and [ - 4, ∞ ) respectively.
An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way.
A set can be represented by its elements or the properties that each of its members must meet can be described using set-builder notation.
Interval Notation: A set of real numbers known as an interval contains all real numbers that fall inside any two of the set's numbers.
Consider the inequality,
x ≥ - 4
In the number line, the value of x is equal to and greater than - 4 increasing to infinity.
Therefore,
The solution set using the set builder notation is:
{x | x ∈ Z, - 4 ≤ x ≤ ∞ }
The solution set of the inequality using the interval notation is:
[ - 4, ∞ )

Consider the equation 8x - 2y= 24. Select True or False for each statement.
8y - 2y = 24
a)
The x intercept is when y = 0; if we use the equation when y = 0:
8x - 2(0) = 24 ==> 8x = 24 ==> x = 24/8 ==> x = 3
So the fist answer is TRUE
b)
The y intercept is when x = 0; if we use the equation with x = 0:
8(0) - 2y = 24 ==> -2y = 24 ==> y = 24/(-2) ==> y = -12
So the second answer is FALSE
c)
if we take the equation and solve it for y:
8x - 2y = 24 ==> 8x - 24 = 2y ==> (8x - 24)/2 = y ==> 4x - 12 = y ==> y = 4x -12
So the third answer is TRUE
