Abstract Algebra

It's rare to see an equation with two equals signs. I'm guessing something else went in between 3z and 9.

3z + 9 = 15, then z = 2

3z - 9 = 15, then z = 8

3z x 9 = 15, then z = 5/9

3z/9 = 15, then z = 45

If I understand the question correctly then a is a proper subset of u.

Made by High Standard, value $150-$200.

I payed $900 for a '82 Honda 450, but it would depend on the mileage, and condition of the bike, to determine the value. Not to mention how much your willing to pay.

i think its the last number in the WORLD.[ literally]

Many of them are valued in price close to $900. The exact amount you can expect will depend upon its condition.

Some sequences are defined by rules and algebra is a mathematical way of describing rules.

It's worth 25 cents.

If: 3r-8 = 2-2r

Then: 5r = 10

And: r = 2

In a computer there are many A/D converters that put analog into digital. This signal is what is usually then led into an op amp which in the right configuration can be designed into an integrator or differentiator which is then used to solve differential equations.

You cannot prove it because it is not true. Some quintics ARE solvable.

For example, if all the coefficients (in a quintic in x) sum to 0 then (x - 1) is a factor. So one solution is x = 1 and you are left qith a quartic. If the sum of odd coeffs equals the sum of even coeffs then (x + 1) is a factor. So, in some cases, at least, quintics are solvable.

If you travel 550 miles in 8.5 hours.... the average speed is 64.70588 mph

No.

They are 165/3-2, 165/3 and 165/3+2 = 53, 55 and 57.

It i a number with the same value but written or represented in a different form.

The op amp differentiator is generally not used in any analog computer application. The basic reason for this is that high-frequency noise signals will not be suppressed by this circuit; rather they will be amplified far beyond the amplification of the desired signal.

There are two types of this note. If the watermark shows King Hussein (a young king at the time), then this is the most common note and is worth $50 to $500, depending on condition. $500 would be the value if it's in undisputably mint condition. if the watermark shows King Abdullah I (older and wearing a turban), then this is a scarcer variety and is worth up to $1,000 in mint condition. In used condition, however, it is still in the same range (perhaps a little more) than the more common type. $70-$100 used. I found this site www.JordanCurrency.com and it discusses all these notes and more.

A matrix is a rectangular array of elements. These elements are usually numbers but need not be. Matrices follow special rules for basic mathematical manipulation (addition and multiplication).

It is: 8

No because irrational numbers can not be expressed as fractions whereas rational numbers can be expressed as fractions

2 of them are associative and distributive but I don't know about the other 1.

(x - y)2 - z2 is a difference of two squares (DOTS), those of (x-y) and z.

So the factorisation is [(x - y) + z]*[(x - y) - z]

= (x - y + z)*(x - y - z)
