Based on the SAS, SSS, and the transitive property of congruence, the reason why ΔABC ≅ ΔGHJ is because of option B.

The SAS is a triangle theorem that states that two triangles are congruent if they both have two pairs of congruent sides and a pair of included congruent angles.

On the other hand, the SSS states that two triangles that have three pairs of congruent sides are equal.

The transitive property of congruence states that if two triangles are congruent to a third triangle, then all three triangles are congruent to each other.

Based on the SSS, triangle ABC is congruent to triangle DEF.

Based on the SAS, triangle DEF is congruent to GHJ.

Therefore, based on the transitive property of congruence, triangle ABC is congruent to triangle GHJ.

The equation of each quadratic in the picture of formula and graphs attached is y=-1(x+8)^2 +9 and y=1/4*(x-6)^2 +3

What is Graph Transformation?

When a graph is transformed, the graph's curve either "moves to the left/right/up/down," "expands or compresses," or "reflects." For instance, by simply pushing the graph of the function g(x) = x2 up by 3 units, the graph of the function f(x) = x2 + 3 is generated. graph transformations are highly useful for graphing functions without having to start from scratch since they allow you to move, extend, compress, or reflect the curve. The graph of the parent function is either "moved," "resized," or "reflected" by a graph transformation. The three primary categories of graph transformations are as follows:

A)

first of all we need to find which type of parabolic graph is it

from the picture give we can clearly see it is a x^2=-4ay type of graph

and using graph transformation formula

i.e. y= a(x-h)^2 + k

where h = -8

k=9

we get y=a(x+8)^2+9

as we know (-5,0) lie on this graph

so,

0=a(-5+8)^2+9

a=-1

so the equation is y=-1(x+8)^2 +9

B)

first of all we need to find which type of parabolic graph is it

from the picture give we can clearly see it is a x^2=-4ay type of graph

and using graph transformation formula

i.e. y= a(x-h)^2 + k

where h = 6

k=3

we get y=a(x-6)^2+3

as we know (0,12) lie on this graph

so,

12=a(0-6)^2+3

a=1/4

so the equation is y=1/4*(x-6)^2 +3

A field of mathematics known as arithmetic operations deals with the study of numbers and the operations on those numbers that are relevant to all other branches of mathematics. The basic operations included in it are addition, subtraction, multiplication, and division.

Calculations involving numbers are done using arithmetic operators. The numerical results that are produced by arithmetic operators are associated from left to right.

The following are the three properties you should consider: Commutative addition applies to full numbers. Associative math is the addition of whole integers. When adding whole numbers, the number 0 serves as an identity.

In several contexts, including multiplication (repeated addition), division, and other operations, the fundamental operations of addition and subtraction are applied (repeated subtraction). These operations are used to transform the word problems into mathematical expressions.

You want to identify the graph of f(x) = (x -1)/(x² -x -6).

The function can be factored as ...

  [tex]f(x) = \dfrac{x-1}{(x-3)(x+2)}[/tex]

The numerator is zero when x=1, so that is where the x-intercept lies.

The denominator is zero for x=-2 and x=3, so those are the locations of the vertical asymptotes.

The graph that has vertical asymptotes at x=-2 and x=3, and an x-intercept of x=1 is Graph A.

Using simplification by factorisation and division

(x² + 6x + 9)/(x² - 9) = (x + 3)/(x - 3) and (3x² - 9)/(x² - x - 6) = 3x/(x + 2)

To simplify the equations, we shall factorize both the numerator and the denominator, and divide through by a common factor.

for the equation (x² + 6x + 9)/(x² - 9);

the numerator:

x² + 6x + 9 = x² + 3x + 3x + 9

x² + 6x + 9 = x(x + 3) +3(x + 3)

x² + 6x + 9 = (x + 3)(x + 3)

the denominator:

x² - 9 = x² - 3²

x² - 9 = (x + 3)(x - 3) {difference of two squares}

(x² + 6x + 9)/(x² - 9) = (x + 3)(x + 3)/(x + 3)(x - 3)

divide through by the common factor (x + 3)

(x² + 6x + 9)/(x² - 9) = (x + 3)/(x - 3)

For the equation; (3x² - 9)/(x² - x - 6)

the numerator:

3x² - 9 = 3x(x -3)

the denominator:

x² - x - 6 = x² -3x + 2x - 6

x² - x - 6 = x(x - 3) + 2(x - 3)

x² - x - 6 = (x + 2)(x - 3)

divide through by the common factor (x - 3)

(3x² - 9)/(x² - x - 6) = 3x/(x + 2)

Thus, (x + 3)/(x - 3) and 3x/(x + 2) are the results for simplifying (x² + 6x + 9)/(x² - 9) and (3x² - 9)/(x² - x - 6) respectively using factorization.

The value of the h is A(2) / b when the formula is A = 1/2bh the formula is area of the triangle.

Given that,

We have a formula A = 1/2bh

We have to find h value from the formula.

We know that,

The variable h should be on one side of the equation, and the rest should be on the other. Divide the two sides in half as a good place to start. In this way, we eliminate the undesirable fraction.

A / 1/2 = 1/2bh / 1/2

Now on the right hand side left the 1/2 cancels out.

A / 1/2 = bh

And when a fraction is divided, the result is the same as multiplying it backwards.

A(2/1) = bh

Now, divide both sides by b.

A(2) / b = bh/b

On the left hand side b cancels out and we are left with the final product.

h = A(2) / b

Therefore, The value of the h is A(2) / b when the formula is A = 1/2bh the formula is area of the triangle.

We know that,

By definition, no function is symmetrical about the x-axis (or any other horizontal line). Because the one flipped with respect to the horizontal violates the vertical line test.

On the other hand, functions can be symmetric about a vertical line or a point. In particular, functions symmetric about the y-axis are also "even" functions, and functions symmetric about the origin are also "odd" functions. Because of this correspondence between graph symmetry and function equality or oddness, "symmetry" in algebra is usually applied to the y-axis and the origin.
