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.

5 plus x equals 2x-3 whats the answer to that question?
Why do we have this nagging feeling that the questioner isn't completely
sure of what the question is ?
We shall now take the given equation and find the numerical value
that 'x' must have in order to make the equation a true statement:
5 + x = 2x - 3
Add 3 to each side: ---> 8 + x = 2x
Subtract x from each side: ---> 8 = x
How do you use measurement at home?
You use volume measurement to measure water and other liquids such as cooking or pouring a cup of water.
You measure the house temperature with a thermometer.
You measure weight (or mass) with a scale to weigh yourself or your food.
You measure velocity (and acceleration) while driving.
You measure distance, length or size with a ruler, or a meter stick or any other measurement tool.
What is the common point of these equations 2x plus 3y equals 12m and x - 3y equals -3?
It is [4m-1, (4m-2)/3]
What is the answers for these y 2 3 2 2-6 3 2 plus 9 and y 3 -3 2 2 plus 9 -3 2 -8?
Without knowing the plus or minus values of many of the given terms it is difficult to formulate an answer and whether or not the question should include any equality signs.
What are the steps for 5 times x plus 5 equals 20?
5x+5 = 20
Subtract 5 from both sides:
5x = 15
Divide both sides by 5 to find the value of x:
x = 3
Is this system a depedent x-y equals 2 and -2x 2y equals -4?
It doesn't look like you have anything that can be determined. The most confusing part of this is the -2x 2y = -4
If y represents the year then
prevalence(y, y+1) = 0.12*(y-1999) + 13.8
Show me an absolute function graph?
It is not possible to show an image here but you can see some examples at the attached link.
What is the solution of the system y equals x plus 5?
The 'solution' is a pair of numbers ... one for 'x' and another for 'y' ... that make the
statement true when you stick the numbers in place of 'x' and 'y'.
There are an infinite number of pairs that work. In fact, almost any pair of numbers
works ... just as long as the 'y' number is 5 more than the 'x' number.
What is the Variable of x plus 6 equals 2?
x + 6 = 2
Isolate the x. Take 6 to the other side, so subtract 6 from both sides (This will eliminate 6 from the left side, and move it over to the right side). 2-6= -4
x= -4
How would you solve this -x2 plus 1 x equals -3 I thinks it's -8 but I do not know?
-x2 + 1 = -3
As a general rule, you should always make the first term positive. This is not absolutely necessary, it just makes solving an equation a little easier. To do this, simply switch the sign of each term:
x2 - 1 = 3
Next, isolate the term with the unknown variable ( x2 ) by adding 1 to both sides:
x2 = 3 + 1 = 4
Lastly, to find x, you must take the square root of x2. To do this, you must do the same to the 4 on the other side. So, just take the square root of both sides to find your answer:
√x2 = √4
x = 2
What is the area of a right triangle when A equals 5 and B equals x plus 5?
It depends on which sides A and B represent: the two legs, or one leg and the hypotenuse.
What is the solution of the inequality -6x-17 greater than or equal to 8x plus 25?
-6x-17 ≥ 8x+25
Add 17 to both sides:
-6x ≥ 8x+42
Subtract 8x from both sides:
-14x ≥ 42
Divide both sides by -14. Since we are diving by a negative number, flip the sign.
x ≤ -3
