Linear Algebra

23 and one half is larger.

Any set of answers that make one sentence will make the other correct. y=2x is the same as 2y=4x because (1,2) and (3,6) would make these correct.

Velocity is measured in metres per second, to find how many metres a body has travelled you need t know the length of time it was moving for.

If a body moves at 10 metres per second for 5 seconds, how far does it travel?

It goes 10 metres every second, so in 5 seconds it must go 5 times 10 metres; 50 metres.

You need to multiply the velocity by the time taken. (m/s) X s = m.

The solution set for the equation 7 * w <= 28 (where <= means less than or equal to) with regard to the unknown variable w, is the set of numbers less than or equal to 4. So the answer is yes since 4 is less than or equal to 4, or simply yes since 7 * 4 = 28 which is smaller than or equal to 28.

Inverse proportion is when one value increases, as the other decreases. For example the number of builders building a wall and the number of days it takes to build a wall are 2 quantities in inverse proportion because the more builders there are, the less time it takes to build the wall (there are more people working on it, so it will be built quickly). As the number of builders increases, the number of days to build the wall decreases. This is inverse proportion.

The parole evidence rule applies when there is a (signed) written document that would be contradicted by oral testimony.

In other words, "if it ain't on the papers, it ain't part of the deal."

int sym_test(const **a,int n){

int i,j,sym;

i=1;j=0;sym=1;

while(sym && i<n){

if ( a[i][j] != -[j][i] ) sym=0;

else if (j<i-1) ++j;

else ++i,y=0;

}

return sym;

}

There is none. y=5 is a straight horizontal line meaning it never crosses the x-axis

Or in other words,

At the x-intercept, y=0. If y=5, then y is unequal to 0. There is no x intercept.

The question does not have enough information in it to properly answer it. (How many "what" per kph.) Please restate the question.

If: -x-3y = -4 and 3x+5y = 16

Then: x = 7 and y = -1

Suppose you have n linear equations in n unknown variables.

Take any equation and rewrite it to make one of the variables the subject of the equation. That is, express that variable in terms of the other (n-1) variables. For example, x + 2y + 3z + 4w = 7

can be rewritten as x = 7 - 2y - 3z - 4w

Then, in the other (n-1) equations, plug in that value for the variable and simplify (collect like terms). You will end up with (n-1) equations in (n-1) unknown variables. Repeat until you have only one equation in 1 variable.

That gives you the value of one of the variables. Plug that value into one of the equations from the previous stage. These will be one of two equations in two variables. That will give you a second variable. Continue until you have all the variables.

There are simpler methods using matrices but you need to have studied matrices before you can use those methods.

Only square matrices have a determinant

4+m

When the lines never intersect, usually when they are parallel.

Unfortunately not all of the notation made it through.

If neither of the variables is raised to some power, say x2 or y3, then the expression or equation appears to be linear.

You use substitution when you can solve for one variable in terms of the others. By substituting, you remove one variable from the equation, which can then be solved.

Once you solve for one variable, you can use substitution to find the other.

Im a student and I do drama at school. If you are talking about "high and low status" as a element of drama, it is used to portray the importance and superiorness of a character, or their insignificance. For example if one character was alot more powerful than the other, that character could be standing, while the insignificant character might be sitting or lying on the ground to portray this. Hope this may be of some help.yes this helps alot

If the slope of a line is 0 then it will either be a horizontal or vertical line depending on where it crosses the x or y.axis

NO, but it goes in 5 times with a remainder of 1.

The x should be to the third power to be a cubic. The way this is written the 3 is a coefficient.
