Calculus
The branch of mathematics that deals with the study of continuously changing quantities, with the use of limits and the differentiation and integration of functions of one or more variables, is called Calculus. Calculus analyzes aspects of change in processes or systems that can be modeled by functions. The English physicist, Isaac Newton, and the German mathematician, G. W. Leibniz, working independently, developed calculus during the 17th century.

How do you answer 2x plus 5 equals -76-7x?
2x + 5 = -76 - 7x
Add 7x to both sides: 9x + 5 = - 76
Subtract 5 from both sides: 9x = -81
Divide both sides by 9: x = -81/9 = -9
What is the solution of 2y-x equals 3 and y equals -5x plus 7?
2y - x = 3
y = -5x + 7
Rewrite the second
y + 5x = 7
Mutiply it by 2
2y + 10x = 14
Now subtract the first equation from this:
2y + 10x = 14
2y - x = 3
11x = 11
Divide both sides by 11: x = 1
Substitute for x in the first equation:
2y - 1 = 3
Add 1 to both sides: 2y = 4
Divide both sides by 2: y = 2
Answer: (x, y) = (1, 2)
What is the value of the discriminant of the polynimial 4x2 plus 7x plus 4?
72-4*4*4 = -15
The discriminant is less than zero so there's no solutions to the quadratic equation.

How do you write x3 plus 2x2-5x-6 in factored form?
x3 + 2x2 - 5x - 6 = x3 + x2 + x2 + x - 6x - 6 = x2(x + 1) + x(x + 1) - 6(x + 1)
= (x + 1)(x2 + x - 6) = (x + 1)(x2 + 3x - 2x - 6) = (x + 1)[x(x + 3) - 2(x + 3)]
= (x + 1)(x + 3)(x - 2)
Find the value of x in the equation x squared equals 6x minus 9?
(X-3)(X-3)
Foil that and you will see tha X = 3. This is a parabola that touches the X axis at X = 3.
What is -6x plus 3y equals -18 -10 plus 5y equals -30 using substitution?
The question is not quite clear, do you mean -6x+3y = -18 and -10+5y = -30?
If so then the solution is:
-10+5y= -30
5y = -30+10
5y = -20
y = -4
Substitute the value of y into the equation -6x+3y = -18:
Answer: x = 1 and y = -4
How do you Simplify 4 over 2X plus 9 over 3X?
You can divide the integers in this case - 4 divided by 2 and 9 divided by 3. You would get 2 over x plus 3 over x.
4/2x + 9/3x = 2/x + 3/x = 5/x
How do you solve x plus 4 equals 8?
x=4
From superscot85: How you solve it is to subtract 4 from each side leaving x = 4
That would be a very simple graph, in the form of a straight line. The line passes through the origin, that is, the intersection of the x and y axes, since as you see from the defining equation y = 3x, when x is zero, y is also zero (3x0 = 0). To draw the line we need only one other point. Let look at x = 4. So, y = 3x4 = 12. We mark a dot at (4,12) and then connect that dot to the origin and voila, we have the graph. The line can be extended as far as you like, of course, it doesn't run only from x=0 to x=4. Lines continue forever.
If: y = 4x^2 -12x -3 and y = x^2 +11x+5
Then: 4x^2 -12x -3 = x^2 +11x+5
Transposing terms: 3x^2 -23x -8 = 0
Dividing all terms by 3: x^2 -23/3x -8/3 = 0
Completing the square: (x-23/6)^2 = 625/36
Square root both sides: x-23/6 = -25/6 or 25/6
Add 23/6 to both sides: x = -1/3 or 8
Therefore the values of x are: -1/3 or 8
What is the answer to -9 - 7x equals -5?
-9-7x=-5
express first the equation in terms of x,
where,
7x=-9+5
then,
7x=-4
thus,
x=-4/7
x/-5 + 8 = 11
To solve this:
Subtract 8: x/-5 = 3
Multply by -5: x = 3*-5
Work it out: 3*-5 = -15
x = -15
Is there a rule to decide if a shape will tessellate?
For regular polygons, the interior angle must be a factor of 360 degrees.
Irregular triangles and quadrilaterals (whose angle sums are factors of 360 degrees) will tessellate. For other polygons, I am not aware of any simple rule.

What is the answer to 5x plus 33 equals 15x-77?
5x + 33 = 15x - 77
Subtract 5 x from both sides: 33 = 10x - 77
Add 77 to both sides: 110 = 10x
Divide both sides by 10: 11 = x
