Step-by-step explanation:
The LHS and RHS are exactly the same, so the equality is true.
The associate property of addition says that
[tex]\boxed{a+(b+c)=(a+b)+c}[/tex]
In order to make the addition of fractions, the denominators should be same. So we can write three fractions as one.
[tex]\dfrac{1}{2} +\left(\dfrac{2}{3}+\dfrac{3}{4} \right )[/tex]
[tex]\dfrac{1}{2} +\dfrac{2}{3}+\dfrac{3}{4}[/tex]
[tex]\dfrac{1\cdot 6 }{2\cdot 6} +\dfrac{2 \cdot 4}{3 \cdot 4}+\dfrac{3 \cdot 3 }{4 \cdot 3}[/tex]
[tex]\dfrac{ 6 }{12} +\dfrac{8}{12}+\dfrac{9 }{12}[/tex]
[tex]\dfrac{ 23 }{12}[/tex]

The centroid of a triangle is the point of intersection of its medians.
The lines that pass through the centroid of a triangle divides the side lengths of the triangle into equal halves.
The figure whose centroid is point G is triangle LMN.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Now, From the attached image, we have the following highlights
There is no evidence that the lines that pass through point G divides the three sides of triangle ABC into equal halves
The lines that pass through point G divides the three sides of triangle LMN into equal halves
The above highlights mean that:
Point G is the centroid of triangle LMN.
Hence, the figure whose centroid is point G is triangle LMN.

Step-by-step explanation:
Multiply the first equation by -2 to get rid of whatever variable. Lets say I wanted to get rid of the variable X to solve for Y. To do that, I'd need to make x, -2x. Now the equation is -2x -8y = -12. If you add the two equations together, you'd get 0 = 0, meaning there are infinite solutions.

The only triangle with the base being bisected perpendicularly is an isosceles triangle or an equilateral triangle. Therefore, [tex]KJ = KL[/tex]
[tex]KJ = 4x + 9\\KL = 11x - 61\\[/tex]
Since the sides are equal, we can equate the expressions to get the equation:
[tex]4x + 9 = 11x - 61\\11x - 4x = 70\\x = 10[/tex]
[tex]x[/tex] is equal to [tex]10[/tex].
Plug that in [tex]11x - 61[/tex] and you get [tex]110 - 61[/tex] which is [tex]49[/tex]. So, Option B is correct :D

Composite functionsComposite function is a function in another function
Given the following functions
f(x)=3x^2-4
g(x)=x^3+5x
f(g(x)) = f(x³ + 5x)
Substitute x³ + 5x into the function f(x)
f(x³ + 5x) = 3(x³ + 5x)² -4
Hence the composite function f(g)(x) is equivalent to 3(x³ + 5x)² -4

If l is parallel to m, solve for x and y.
Answers
Answer:
Step-by-step explanation:
3x + 49 = 7x - 23
4x = 72
x = 18
11y - 1 = 3(18)
11y = 55
y = 5
The value of x is 18 and y is 5.
What are the properties of parallel lines?Following are the properties of parallel lines,
The pairs of vertically opposite angles are equal.The pairs of corresponding angles are equal.The pairs of alternate exterior angles are equal.The pairs of alternate interior angles are equal.Given:
<1 = 7y -23
<2 = 11y -1
<3 = 3x
Using corresponding angle
7x - 23 = 3x + 49
4x = 72
x = 18
again, Using corresponding angle
3x = 11y - 1
3(18) = 11y - 1
11y = 55
y= 5
Hence, the value of x is 18 and y is 5.

Identify the parent function.
Answers
Answer: D) Absolute Value
Step-by-step explanation:
From the graph, we can see that the function is the absolute value.
From the graph, we need to identify the type of parent function.
What is parent function?In mathematics, a parent function is the simplest function of a family of functions that preserves the definition (or shape) of the entire family.
From the graph, we can see that the function is the absolute value.
An axis of symmetry of the graph of a function is a vertical line that divides the graph into mirror images. An absolute value graph has one axis of symmetry that passes through the vertex. The absolute value function is defined by f (x) = |x|. This is the absolute value parent function.
Therefore, from the graph, we can see that the function is the absolute value

In a group of 27 pupils, 7 play the flute only.
5 play the piano only.
10 play both instruments.
A student is chosen at random.
What is the probability the student plays neither instrument?
Answers
Answer:
5/27
Step-by-step explanation:
I wrote it as a fraction, but the explanation is, if you're finding out how many who don't play instruments, you first need to find out who many do play instruments, so you add the numbers together.
10+5+7 = 22
So the probability that you'll pick one who does play an instrument would be 22/27 (because 22 out of the 27 pupils play an instrument.) But remember that's not what it's asking us for.
You have to subtract 27 - 22 to get the pupils who don't play instruments, you get 5, so the probability is 5/27 (5 pupils out of 27 don't play instruments.)
To put this in a percent, just divide the top number by the bottom number and move the decimal 2 places over, you get 18.5% or 19% both answers are correct depending on rounding.

Let's solve your equation step-by-step.
2x+9=8x+21
Step 1: Subtract 8x from both sides.
2x+9−8x=8x+21−8x
−6x+9=21
Step 2: Subtract 9 from both sides.
−6x+9−9=21−9
−6x=12
Step 3: Divide both sides by -6.
-6x/-6=12/-6
x=-2
Answer:
-2 = x
Step-by-step explanation:
First, combine like-terms. I subtracted 21 from both sides and subtracted 2x from both sides. This gave us 12 = -6x. Then, divide to solve for x. This gives us -2 = x.
