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 solve -x plus y equals 1 and -2 plus y equals -2 by substitution?
-x+y = 1
-2+y = -2
y = 1+x
y = -2+2 => y = 0
By sustituting the values of x and y can be found
x = -1 and y = 0
Remember that a minus from a minus is equal to a plus. So - -1+0 = 1
Which is the greater rate of change y equals 2x plus 1 or y equals -3x - 1?
The second equation has the steeper slope.
What is the answer 3x plus 37?
Without any knowledge of x, all that can be said is that it is 3x + 37.
Since x is a constant (2.8) the only variable changing would be y, that means that it is a vertical line that crosses the x-axis in 2.8

It's about 6 miles. The actual way to calculte is 5/8ths. The is 5 miles = 8 Kms. Therefore multiply by 5 & divide by 8= 45 divided by 9 = 5.6 miles.
Which point lies on 2x plus 5y equals 10?
First, in this form. Y =mX + c
2X + 5Y = 10
5Y = - 2X + 10
Y = (-2/5)X + 2
Y = 2
----------0 out equation
(- 2/5)X + 2 = 0
(- 2/5)X = - 2
X = 5
---------
(0, 2) and (5, 0)
------------------------------ points on the line
What is the answer for 7 plus 3 x -3?
When solving these types of problems, follow BEDMAS.
B-Brackets. You always answer the equation in the brackets first.
E-Exponents. For instance, 3 to the power of 3 isn't the same as 3x3 because you're multiplying 3x3x3=27.
D-Division
M-Multiplcation. Division and multiplication go together. For example, 8x2 divided by 4. Even when you divvide 2 by 4 first, then multiply 8 by 2, it's the same product as doing it the other way around, but you must always answer from left to right when it comes to division and multiplication; and addtion and subtraction, but with brackets as an acception.
A-Addition
S-Subtraction *These go together!
Now, using BEDMAS, you can now answer the operation.
7+3x3
=7+9 (because 3x3=9)
=16
