Experts from the World Health Organization just expressed concern for the rising number of measles outbreaks across Europe. Despite a perfectly capable existing vaccine, "immunization coverage has dropped below the necessary threshold of 95%," causing the measles to spread throughout the European region.
From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts. And, thanks to the Internet, it's easier than ever to follow in their footsteps (or just finish your homework or study for that next big test). With this installment from Internet pedagogical superstar Salman Khan's series of free math tutorials, you'll learn how to solve a system of linear inequalities by elimination.
\When both equations in a linear system are in the form Ax + By = C, you can solve the system using elimination. How is this method different from substitution? The idea behind the elimination method is to create a new equation from a combination of the original equations in the system. The new equation is formed by adding or subtracting the originals. When we combine two true equations, the sum or difference must also be true.
This video helps us understand the organic molecules and elimination reaction. Take some sugar in a beaker. Sugar has 12 carbon atoms, 22 hydrogen atoms and 11 atoms of oxygen. The sulphuric acid is poured into the sugar and the color change is observed. The color of the sugar gradually changes into black. The sulphuric acid causes an exothermic reaction which releases a large amount of sulphur dioxide gas. All the water (containing hydrogen and oxygen atoms) is eliminated out of the sugar du...
Elimination in mathematics is used to find the solution set of a system of equalities. This video tutorial shows how to use elimination to find the solution set of a given equation and offers several examples to illustrate the process. Before applying this method, the equation must be in the form “Ax +By=C.” When graphing a set of mathematical equations that intersect, the answer to the elimination is the point on the graph where the two lines cross.
The video shows us how to solve a system of equations with the elimination method. First write the two equations one on top of the other, as it is going to be elimination method and it is recommended to write it in that way. Here the 2 equations are x+y=-3 and x-y=1. In the elimination method we need to add the 2 equations by columns. So adding it column wise we get to have 2x=-2 and solving this we will get the value of x=-1. Then you need to substitute this value of x in any of the two equa...
In this video the instructor shows how to solve a system of equations by elimination method. First you need to know how many possible number of solutions you can get by solving a system of equations. There are three possibilities. In the first case there are two lines with different slopes, so they intersect at a point which is the solution to that system. In second case there can be two lines with same slope but are parallel to each other. In this case the system has no solution. In the thir...
A close look at using matrices, Gaussian elimination, and determinants. This video is good for beginners who have never used a matrix before.
This video is about using the elimination method to solve a linear system. The lady presenting this video says that elimination method means that one of the two variables has to be eliminated while adding up the two linear equations. She then explains the example equations 6x-2y=66 and 5y=-29-2x. She asks you to first line up x and y. So the second equation is rewritten as 2x+5y=-29. Then she says that, to eliminate a variable, we should have their variables equal in value but of opposite sig...
If you suspect that you have some sort of food sensitivity or allergy that is giving your body negative symptoms (such as skin breakouts) or bringing down your overall well-being, you should, try going on an elimination diet.

Nineteen days ago, several hundred people could have been exposed by a traveler with measles in Nova Scotia, Canada. The next day, someone flying from Minnesota to Nebraska may have spread the measles to other passengers. A couple weeks ago, it's possible that a man and his six-month old child spread the measles in several Seattle-based locations. Authorities are trying to locate persons who may have been in contact with these people. None of the persons with measles were vaccinated. Why?
You may not have heard of visceral leishmaniasis, onchocerciasis, or lymphatic filariasis, and there is a reason for that. These diseases, part of a group of infections called neglected tropical diseases (NTDs), impact more than a billion people on the planet in countries other than ours. Despite the consolation that these often grotesque illnesses are "out of sight, out of mind," some of these infections are quietly taking their toll in some southern communities of the US.
If you've been keeping tabs on the rumor mill for the iPhone 7, one of the most discussed elements of Apple's upcoming device is the possible elimination of the headphone jack in favor of a Lightning connection.
There's been a lot of speculation as to what Apple's next iPhone models will have in store for us. There's a lot of credible rumors about the iPhone 7, but is there also a Pro model in the works? We may actually have a legitimate sneak peek at what that device could look like.
The Google Cast feature that serves as the primary interface for the Chromecast and comes bundled with Android TV devices like the Nexus Player is a marvel of modern technology. But as these things go, troubleshooting issues can be difficult with something so groundbreaking, especially when you consider that there are two parts to the equation—the casting device (your phone, tablet, or computer) and the receiver.
When LinkedIn first arrived on the scene, I thought it was a great resource for staying connected and getting in touch with those people in your desired career path. Keyword: Thought.

Since Motorola engineer Bill Smith invented Six Sigma in 1986, corporations around the world have employed it to eliminate costs and process cycle time while increasing profits and customer satisfaction. These techniques and tools for process improvement were invaluable to famed CEO Jack Welch, who used them to redefine General Electric's business strategy in 1995.
A recent initiative by the Cherokee Nation American Indian Tribe delivers a success story for knocking out a silent killer — Hepatitis C.
Activating the body's own immune system to fight cancer is the goal of immunotherapy. It's less toxic than chemotherapy and works with our body's natural defenses. The trouble is, it doesn't work for most patients — only about 40% of cancer patients get a good response from immunotherapy. But coupling it with another type of cancer therapy just might deliver the punch that's needed to knock out cancer.
Tremendous strides have been made in the treatment and outlook for patients infected with HIV, the human immunodeficiency virus. Treatment with a combination of antiretroviral drugs can keep patients with HIV alive for decades, without symptoms of the infection. The trouble is, if HIV-infected people stop taking their medications, the virus takes over in full force again—because the virus hides out quietly in cells of the immune system, kept in check, but not killed by the treatment.
The 2021 season of Major League Baseball (MLB) is in full swing, and now that vaccines are widespread in the US, major baseball stadiums are allowing fans back in at full capacity.
Last week, augmented reality startup Proxy42 released Father.IO, a multiplayer game that turns any indoor or outdoor space into a laser tag arena.
HIV-infected people who are treated long-term with antiviral drugs may have no detectable virus in their body, but scientists know there are pools of the virus hiding there, awaiting the chance to emerge and wreak havoc again. Since scientists discovered these latent pools, they have been trying to figure out if the remaining HIV is the cause of or caused by increased activation of the immune system.

In this math lesson you will learn how to solve systems of equations. Systems of equations usually have 2 equations and two variables. You can solve a system of equations by using one of the following methods.
In each day of our life, we see inflammation. We see it during sore throats and abscess formations in our bodies, and even slight tooth pain is a form of inflammation. Sometimes it's good when it fights to protect us from invading organisms, but sometimes it becomes bad when it occurs in inappropriate ways, like acne.

Wireless contracts and phone-buying programs continue to become more and more confusing. As if you didn't have enough to worry about with regards to the rising costs of services and the elimination of contracts with mobile providers, Verizon Wireless will soon institute a new charge that puts the grub in "money-grubbing." Sadly, this isn't one of those April's Fools pranks that are running rampant on the web today. Starting next week, the largest mobile phone provider in the United States wil...
It's soon going to be time for the elections and everyone is prepping up for it. The Republicans are waiting to elect Romney, who in my and many others view will not keep his promises. The Democrats are trying their best (its working) to make Obama as strong as possible against Mitt, who, in their minds, will be easy to defeat. Obama's acceptance polls have been steadily rising in the past few months.
The noble board game has stalwartly staved off elimination in the face of more technologically advanced video games for four decades. Try as they might, video games just can't seem to surpass them as an easy-to-use diversion for large groups of seated indoor people.
