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.

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
Which is the greater rate of change y equals 2x plus 1 or y equals -3x - 1?
The second equation has the steeper slope.
If 3x - 1 11 what ia the value of x2 x?
Unfortunately, the browser used by Answers.com for posting questions is incapable of accepting mathematical symbols. This means that we cannot see the mathematically critical parts of the question. We are, therefore unable to determine what exactly the question is about and so cannot give a proper answer to your question.

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.
What is the basic definition of differential equation?
An equation where some terms are derivatives of functions. Usually the problem is to find the function that makes the equation true.
If a drag racer travels 3 tenths of a mile in 8 seconds what is the rate of acceleration?
It is impossible to determine acceleration simply from time and distance.

You can get your answers here, if you post the questions one at a time.
If you do that, you'll have all of your answers, probably within a week. But you won't be able to
solve the problems, any more than you are now, so the answers won't do you any good.
By a long shot, the very best person to help you with these problems is your teacher.
What is the value of x when 3x is less than -2x plus 15?
Treat as equation.
3X < - 2X + 15
add 2X to both sides
5X < 15
divide both sides by 5
X < 3
Must be, because putting 3 in for X gives you an equality, so X has to be less than that 3 found.
How do you evaluate the integral of 2udu divided by 1 plus u squared?
for the integral of (2x)dx/(1+x2 )
Take (1+x2 ) as your 'u' substitution.
find du, du= 2x dx
use u substitution to write new integral, integral of du/u
the integral of du/u= ln abs(u) + C
therefore, your original problem becomes an answer with ln
ln abs (1+x2) + C
*abs refers to absolute value of the parentheses
