This would be something that goes along with your class. You could get the website from your teacher to begin.

There is no one answer. This is an equation for a straight line.

2x = 3y + 10 is linear. !!!!

In straight line form it is

3y = 2x - 10

y = (2/3)x - 10/3

This one looks like No Solution. This is how I read it: 5x = 8 = 98-4x. If 5x = 8, then x = 8/5 = 1 3/5 (or 1.6), substitute into 98 - 4x --> 98 - 4(1.6) = 91.6, which does not equal 8, as it should from the equation.

For any integer value of x ≥ 0, there are two values, ±y, such that x! = y2.

For example, if x = 3 then x! = 6 and so y = ±√6

It is a singular matrix.

Periodic or cyclic neutropenia is a disorder which causes frequent infections. This condition in which neutrophils, a type of white blood cell, decrease on a regular basis is extremely rare and has been shown to be a genetic mutation.

x = -5

yes

There are none. Those two curves do not intersect.

x2 - 4x - 9 = 0

∴ x2 - 4x = 9

∴ x2 - 4x + 4 = 13

∴ (x - 2)2 = 13

∴ x - 2 = ±√13

∴ x = 2 ± √13

The equation y = 13x is in the form "y = mx + b" (in this case, b is zero). Therefore, the equation is linear.

x+2y = 1

2y = -x+1

y = -1/2x+1/2

Slope = -1/2 and the intercept is 1/2

If 4x - 1 = -5, then adding 1 to each side gives 4x = -4 and dividing, x = -1

It is true that if when x is getting larger, y is getting smaller, that would be an inverse relationship.

3X - 16 = 2

add 16 to both sides

3X - 16 + 16 = 2 + 16

3X = 18

divide both sides integers by 3

(3/3)X = 18/3

X = 6

----------------check in original equation

3(6) - 16 = 2

18 - 16 = 2

2 = 2

-------------checks

yes,but only when it has nothing else avalable

A relational model is the means of ordering elements that relates to one another, called a tuple.

Multiple tuples of similar structure can be seen as a table, with rows that describe each tuple, and similar elements ordered in columns.

All operation are described as binary operation as in calculus, e.g. "Insert" is the same as addition, as a new relation is added, where the elements in the relation constitutes a new unique group of values.

Any tuple can have a relation to another tuple - such as "they belong together" or "one comes after the other".

That relations can be represented as tables is used by a number of application building tools, such as MS Access. These refer to the similar elements - the column by assigning them names. They will usually also assume a similar datatype (int, numeric text, float, code, text, etc). The relation model is entirely based on mathematics, relational calculus and relational algebra developed by Chris Data and Ted Codd at Watson Height, IBM Research Center.

The relational model does not relate to any relationship between the tables, and relationships needs to be coded by the application programmer that use codes to make e.g. a parent relates to child. The database system can implement constraints such as that every child has a parent, while not every person has a child.

The model is then used by application developers to create the user interface.

The competing model is the CODASYL network model that was made to satisfy the requirements for application support. This will provide "pointers" that can link a child to a parent, and an order line to a order. However, these does not lend themselves to allow generic tools such MS Access to make the applications, as it does not support the flexibility needed to "just make it".

The min and max is when the first derivative , or slope at any point, is zero.

For f of x = 2x first derivative is 2, so this is constant slope with no min or max as this is not zero; min is thus negative infinity and max is infinity

The x intercept is where y = 0, on the x-axis. So plug in y=0 to you equation:

-5(x) + 20(0) = 20 ... -5(x) = 20...

Divide each side by -5: x = 20/-5 = -20/5 = = -4.

Therefore the x intercept is where y = 0 and x = -4 --> (-4, 0)

Set up the equation and solve:

x + 5 = -13 (next subtract 5 from each side of the equation to solve for x)

x = -18

The answer to the problem of 7-3x equals 34 is x equals -9.
