" -7y plus 1975 " is not an equation, it doesn't ask any question, and it needs

no solution.

It's just an expression that stands for a number. There's no way to know what number

it stands for until you know what number 'y' is.

Yes.

Yes.

Yes.

Yes.

y = x + 14.

The answer is 8.89 cm (approx.). Inches and centimeters are both units of linear measurement. Inches are used in the imperial system whereas centimeters are used in the metric system. To convert from inches to cm, multiply the inch unit by 2.54.


To convert from inches to centimeters, multiply by 2.54.

You seem to be unaware of the fact that you could have obtained the answer much more easily and quickly by using the calculator that comes as part of your computer.
The answer is 24404.

There are 1.518631194 miles in 2,444 meters. 2,444 meters x 1 mile/1,609.344 meters = 1.518631194 miles 1 miles = 1,609.344 meters

The slope of the equation y=-7x +6 is -7 or -7/1... The standard form is y=mx+b, m being the slope.

In-line functions differ from normal functions by the way they are dealt with by the compiler.

Normally, a function (or its code, more exactly) is stored once within the executable program. A call to this function then results in putting the parameters onto the stack and jumping to the start address of the function. When the function is finished, the stack is freed from the parameters and the program continues right after the point from where it has jumped to the function.

For an in-line function, its code is stored at any place where it is called. This saves us from the administrative overhead (putting parameters etc. onto the stack and cleaning up at the end) and, thus, reduced computing time. On the other side it enlarges the eecutable.<br>

This leads to some restrictions to inline-functions.

Just like numbers, polynomials can be prime in some way, although this is usually referred to as being irreducible. Your polynomial is not in fact irreducible since it can be decomposed into (x-4)(x+3). This also means that plugging in any integer value for x gives a factorisation for the number x^2-x-12, which is (x-4)(x+3), so the value of x^2-x-12 for any integer x can only be prime if either x-4 = 1,-1 or x+3 = 1,-1 so for x=5,3,-2,-4. Now for x=5 we get 25-5-12=8, which is not prime. For x=3 we get 9-3-12=-6, which is not prime either. For x=-2 we have 4+2-12=6, which again is not prime. And for x=-4 we have 16+4-12=8 again, which of course is still not prime. So not only is your polynomial reducible, also any value it takes when plugging in an integer x will be composite. An alternative way of establishing this fact would have been to note that this polynomial only takes even values for any integer x and that the value 2 is not in fact attained for any integer x.

0 is the identity under addition for integers, rationals, reals, complex numbers. This means that 0+x = x+0 = x for all x.

The above answer is correct, but with some mild "un0carefulness" as we call 0 the identity BEAUSE 0 + x = x + 0 = x for all x in those sets.

As a matter of fact, we want something in our sets with an operation to be the identity, we just decided to call it 0.

In other words, we DEFINE 0 as a element in a group, ring, field, or other number systems where 0 + x = x + 0 = x for all x.

By the way, if you don't like it, you can call it something else. Like @ + x = x + @ = x for all x. You just have to define it. Then you can use it on your papers :P After all, 0 without a definition is just a symbol.

Yes, it sure is.

The square root of 59,834,759,834 is: 244,611.44665366746

1. It can have a unique solution. On a graph this would be single point of intersection.

2. It can no no solutions such as two parallel lines on a graph.

3. It can have an infinite number of solutions such as two equations that represent the same line on a graph.

You can make up examples to see this very easily.

For number 3, take any linear equation such as y=x+1

Now multiply both sides of the equation by 10 10y=10x+10. The solution to the system of those two equations is all real numbers, an infinite solution.

Now for number 2, take any line and just find a parallel line. Easy to do by simply making sure it has the same sloe but a different y intercept.

For the last one, take two lines that intersect. This will most often be the case if you randomly pick two linear equation. Say y =x+1 and y=3x+13. Different slope and different y intercept.

The Range is all the Real numbers you can think of.

The Domain is also all Reals.
