Answer:

The slope is 0 the line is constant.

Step-by-step explanation:

.

The slope of side LN is 0.

In an isosceles triangle, if two sides are equal, then the angles opposite to the two sides correspond to each other and are also always equal.

Now, in the given isosceles triangle LMN,

Coordinates of vertices are,

L(x₁,y₁)  =  (0, 1),

M(x₂,y₂) = (3, 5), and

N(x₃,y₃) = (6,1)

The slope of side LN ,

Slope = (y₃ - y₁)/(x₃ - x₁)

⇒ Slope = (1-1)/(6-0)

⇒ Slope = 0

means " LN is a horizontal line".

Thus, the slope of side LN is 0.

Explanation:

If g(x) is the inverse of f(x), and vice versa, then we have these two properties:

Since we want to find a function that is its own inverse, we want f(x) and g(x) to be the same function.

Through trial and error, you should find that f(x) = g(x) = x fit the description.

f(x) = x

f( g(x) ) = g(x) ... replace every x with g(x)

f( g(x) ) = x

You should find that g(f(x)) = x as well.

One possible answer is f(x) = x

---------------------------

Through more trial and error, you should find that f(x) = g(x) = 1/x works as well. In fact, anything of the form f(x) = g(x) = k/x will work.

The proof can be written as follows

f(x) = k/x

f( g(x) ) = k/( g(x) )

f( g(x) ) = k/( k/x )

f( g(x) ) = (k/1) divide (k/x)

f( g(x) ) = (k/1) * (x/k)

f( g(x) ) = x

Through similar steps, you should find that g(f(x)) = x is the case also.

This proves that f(x) = k/x is its own inverse, where k is a real number constant.

Another possible answer is anything of the form f(x) = k/x

If we pick k = 3, then we get f(x) = 3/x which is the answer I wrote above.

You can pick any k value you want.

---------------------------

There may be other types of functions that have this property, but I'm blanking on what they might be.

The solution for x is x = (y + 49)/7.

Given that an equation 7x - 49 = y, we need to determine the equation in for of x,

To solve for x in the equation 7x - 49 = y, we'll isolate x on one side of the equation.

Here's the step-by-step process:

Start with the given equation: 7x - 49 = y.

Add 49 to both sides of the equation to isolate the term with x:

7x = y + 49.

Divide both sides of the equation by 7 to solve for x:

(7x)/7 = (y + 49)/7.

Simplify:

x = (y + 49)/7.

Therefore, the solution for x is x = (y + 49)/7.

Answer:

$3

Step-by-step explanation:

Let c represent the cost of a box of cereal and let m represent the cost of a jug of milk.

Create a system of equations:

2c + m = 8.5

3c + 2m = 14

Solve by elimination by multiplying the top equation by -2:

-4c - 2m = -17

3c + 2m = 14

Add them together and solve for c:

-c = -3

c = 3

So, a box of cereal costs $3

A box of cereal cost $3 if two boxes and a jug of milk cost $8.50, and three boxes and two jugs of milk cost $14.00.

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, two boxes of cereal and a jug of milk cost $8.50, and three boxes of cereal and two jugs of milk cost $14.00

Let c stand for the price of a box of cereal and m for the price of a milk jug.

The obtained system of equations is as follows,

2c + m = 8.5

3c + 2m = 14

Multiply the top equation by -2 to reach the solution by elimination:

-4c - 2m = -17

3c + 2m = 14

Put them all together to find c:

-c = -3

c = 3

Thus, a box of cereal cost $3 if two boxes and a jug of milk cost $8.50, and three boxes and two jugs of milk cost $14.00.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

2a is five times bigger than b. Then the equation is given as,

2a = 5b
