First-degree equations with

fractions and parentheses. Boys and

How are you girls, welcome to the

math channel with John and we're going to

solve this equation where you have to

to be very careful with this sign

less that affects the parentheses, it's about

of a first degree or degree equation

1 with fractions and parentheses. Before

throw ourselves like crazy to solve this

first-degree equation we have to

understand what solving an equation is,

what we're doing when we say

"we're going to calculate the solution of a

first-degree equation." Well, we have

to know the following. First we have

to know that there's some kind of function

which are called linear

and this is the general form of a

linear function. These linear functions

have a very nice property and is that

if we represent them on the plane

Cartesian it turns out that they are always

straight lines, are straight lines, lines

that can be in many ways.

It may be so, it may be so, .... Well look,

I'm going to draw one, specifically this one.

This is a straight line,

is given by a linear function and look,

this straight line against the x-axis.

at this point. Well, guys, it turns out

that linear functions can be

equal to zero. Look, this function

I'm going to equalize it to zero.

Solve an equation, an equation of

degree one, is to calculate this point of

cutting, the cutting point on the axis of the

"x", at which point the function cuts off the axis

of the "x's." This is really what

means solving an equation of

first grade and we're going to solve

an equation right now of the first

degree, that is to say, we what we are going to

to do is to find out at what point the function

next, at which point the function

next (x, two, minus one third less

3x, 6, minus 1 match of 12) at what point

This function shortens the "x" axis.

and let's go, let's go for it, let's go

solve it, we're gonna solve it. What's the point?

Point will it be? At what point will it be? At what point will it be?

point will cut this function to the axis of the

"x"? We just saw the preamble more

important, understand the problem well.

Now we're gonna figure it out, we're gonna

solve it. Come on, guys.

Before we solve we have to look at a

little, to study a little this equation of

first degree, linear equation and so

we see that, boys, girls,

this can be simplified. Do we have three

sixths? This equation can be ... three sixths

we can write it as... if we divide it.

up and down by 3, dividing up

and down between 3

we're going to have that this fraction is

equivalent to this one. Yeah? If we split up

up and down between 3 we have this. Okay.

Well, a half, a half. We rewrite this

equation of the following, of the following

way: "x" means minus one third minus "x"

means equal to 1 game of 12. Good!

Our next step is to remove this

parentheses. A lot of care, a lot of care

watch out for this minus sign because this

less sign affects the signs that there are

within the parentheses and a super error,

but super typical, go here to see

the most important errors of the

mathematics,

a super typical mistake is to do what

next: "x" means minus one third less

"x" means 1 match of 12.

Guys be careful because these are no less,

this is more, because less for less is

more and I'm going to put here the sign implies,

pardon, the equivalent sign

and we go on, we go on. Here we have our equation,

our equation a little more

simplified and we see that we have

[Music]

fractions, we see that we have fractions.

Ah, look! We have here "x" means and here "x".

means. "x" means plus "x" means, this such

time we could write it from the next

way: then "x" means plus "x" means

(we can write it that way, of course)

minus a third equal to 1 match of 12,

that is to say, 2x party of two, minus one

third and this would be equal to 1 game of

12. 1 game of 12. We can simplify

here, here we can simplify 2 above 2

downstairs. We simplify and this is

equivalent to "x" minus one third equal to

1 game of 12.

Well, well, well, well, well, well, well.

Ah, look, look how beautiful! The "x" the

we're almost, almost ready to be

clear. Look, we have the "x" minus one

third. Boys are less than one third that

there is here I can make you the following

play, I can add here a third and

add here a third, whatever you do in a

member I do in the other, this is the

game that is always done with the

equations and doing this little game,

minus one-third plus one-third we are

would go, this would go away and we could

write, we could write that

"x" is equal (let's put the east sign of

equivalence) "x" is equal to 1 match of

12, 1 match of 12, plus, plus

A twelfth plus a third? I am

to do up here.

A twelfth plus a third, look.

we could make the least common multiple

of 12 of 3 and blablabla.

To trade fractions using minimum

common multiple go to this video, but I

here I'm going to do something else, here I'm going to

to do something else. I'm going to do it

understanding a little the handling of

fractions. Look, I want these two

fractions have the same denominator.

What can I do to make this fraction

has the same denominator as this one? Well

what I can do is this: I can

multiply this fraction by this one,

4 out of 4.

And doing this little trick, doing

this little trick just watch what happens.

This is what happens.

I happen to have 1 game of 12 + 4 by

one is 4 and 4 by 3, 12. Ha, ha! Now I have

the same denominator, then this is the same

a

5 games of 12. Little friends, little friends.

little friends, I can write that this is

equal to 5 games of 12. And colorín

colored

the equation is over. The one who

solution of this equation is "x" equal to

5 twelfths means the following:

means

the function associated with this equation is

i.e. the function

x means less than one third less 3x

match of 6 minus one twelfth

this linear function, it turns out that

I don't know how, how it's going to be (this is

a straight line) I don't know how it's going to be

oriented, but I know that

is going to cut the x-axis in a

period. Well, this point is going to be worth

Five-twelfths. This is what it means

solving a first-degree equation is

say I'm calculating for which values

it is fulfilled, it is fulfilled the following, that

"and" equals zero.

Good friends good friends we have

at the end of the exercise, I say goodbye to

you. Perhaps you would like to subscribe,

then subscribe, subscribe. You

Goodbye!

Consejos y cuidados para la displasia de cadera de tu perro - Duration: 4:34.

Hip dysplasia is a bone disease that affects numerous dogs, especially

to those of big and giant race.

But do you really know what it is and how it produces?

And more importantly: if your pet suffers, Do you know what care you can provide?

Provide chondroprotectors and choose the most appropriate food are some tips

that we give you in this article.

What is hip dysplasia?

As we said at the beginning, it's a disease bone that involves the malformation of the joint

coxofemoral, that is, the one that joins the hip and the femoral head.

It is hereditary and not congenital, that is, it does not manifest itself at birth but rather it starts

to perceive as the puppy grows (from 4 months to 12 months of age).

Being degenerative, the disease goes further, sharpening your symptoms, such as lameness and pain.

It has a higher incidence in breed dogs big and giant, more likely to suffer

joint problems

However, it can also be manifested in any type of race, especially in

those that experience very fast size and weight in puppy age.

I think for dogs and other cares to have consider

Hip dysplasia is a genetic disease, so you can not talk about measures for

prevent its appearance.

However, you can have certain considerations to diagnose it in phases

early, slow it down and mitigate its effects.

Regarding diagnosis, there are different tests that have emerged recently.

The PennHip test is one of them, which indicates the odds that a certain dog

suffer this disease.

There is also the Dysgen Test, developed by Bioibérica, which focuses its analysis on

Labradores Retriever, one of the most breeds affected by hip dysplasia.

As for the slowing down of the disease, it is important to take care of your dog's diet,

especially at early ages.

You must offer feed for puppies of veterinary range, according to your advice

vet.

This control of the diet must continue in adult ages, avoiding dog food

common: weight control in animals with dysplasia must be strict so as not to aggravate

the symptoms of the disease.

In addition, the ideal is to provide chondroprotectors, indicated for dogs with joint problems.

Its goal is to reduce the inflammation of the cartilages and improve their elasticity and

flexibility.

Another aspect to consider is sterilization, especially if your dog is Golden

Retriever, because according to a recent study from the University of California at Davis,

the cases of hip dysplasia are doubled in this race when the sterilization is

occurs before one year of age.

As for the treatments that can receive dogs with hip dysplasia are

the Conservatives.

They include the aforementioned veterinary diet based on feed for dogs with problems

joint

It is also worth mentioning the use of chairs wheels or special supports, which will allow

walk the dog with less effort and pain, especially when the disease is already

widely developed.

There is also the possibility of submitting the dog to a surgical intervention.

The professionals of the veterinary team will determine which is the most appropriate option and what results

can provide.

Some of the possibilities are the Triple Pelvic osteotomy or replacement of

the hip joint by a prosthesis, among other.

Some have healing purposes and others, palliatives.

As regards the online catalog of Animalear, on our website you will find different

products aimed at dogs with dysplasia Hip.

On the one hand, chondroprotectors, and another, veterinary pet range feed

with joint problems.
