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 rewrite and solve for y 2x less than y plus 7?
your equation is this...
2x < y + 7
Now solve for y...
2x - 7 < y
Since you have two variable the most you can get out of (y) is the graph and the y-intercept.
the y-intercept is y > -7
0.25 * 5 = 1.25
It would have been quicker to use a calculator and you cannot be sure that I have got the correct answer!
What is the rational zeros for x3 plus x2-17x plus 15?
x3 + x2 - 17x + 15 = (x - 1)(x - 3)(x + 5).
Thus, the zeros are 1, 3, and -5.
All three zeros are rational.
What is 16x squared minus 12x plus 9?
It's a second degree trinomial in 'x'. Its numerical value depends on the value of 'x'.
========================================================================
The first contributor observed:
Very nice exercise with the quadratic formula. But it doesn't apply here.
The formula is used to solve a quadratic equation, but there's no equation
here ... the question doesn't say that the trinomial is equal to anything.
If the trinomial were equal to zero, then your application of the formula
is the way to solve it; but as it stands, there's nothing to solve.
Also BTW: (B2 - 4AC) < 0 doesn't mean no roots. It means a pair of imaginary
or complex conjugate roots. A quadratic equation alwayshas two roots, even
though they may be equal or imaginary.
How do you solve the problem x-5 equals 2x?
First, you have to know what 'solve' means, so you know what you're looking for.
'Solve' means find a number for 'x' that will make the problem a true statement
when you plug that number in wherever 'x' appears.
Here's how to find it. First, write the problem down and look at it:
x - 5 = 2x
Now subtract 'x' from each side:
-5 = x
And there you are.
What is the relationship between relation and function?
A function is a relationship that is one-to-one or many-to-one but not one-to-many.
Thus, if a and b are in the domain of the function, then their images in the range, f(a) and f(b) MUST be equal.
What is the answer to 5x 2y equals 44?
Furthermore, there can be no answer to one linear equation in two unknown variables. You need two independent equations in order to solve for the two variables.

He needs to continue his therapy--time is the best indicator of how he will deal with his feelings. If you don't feel he's making an honest attempt to change, and is going through the motions only to keep you from leaving, end the relationship. You can't change his behavior for him--he alone has the power to do that. If you decide to stay with him, the best thing for you to do is to set boundaries. Make it absolutely clear that any further incidents of abuse are the dealbreaker of your relationship. Neither of you have the right to physically or verbally abuse the other. Don't use his violent act towards you as ammunition in arguments or as a way to get him to do what you want. You are wise to consider distancing yourself from him. Just because he is in therapy isn't enough for you to waffle about forgetting the hitting incident. He still has a long road to behavioral health, and you have to heal.
How many pounds of sand to fill a 7' x 8' x 12 sandbox?
It depends on the density of the sand. Certainly, you are talking about 56 cubic feet, but you will need to know the bulk density of sand to figure out how much that weighs.
What is the pH of a solution with a H plus equals 1.4 x 10-3 M?
-Log(1.4x10-3)= 2.85
The Log to be used here is the decimal one, not the neperian one.
How much is 18 equals 3 plus 5x for x?
Your question is actually: "What is 'x' if [18 = 3 + 5x] ?"
18 = 3 + 5x
Subtract 3 from each side of the equation:
15 = 5x
Divide each side by 5:
3 = x
What happens to y as x moves towards negative infinity?
The value of y as x changes depends on the function under consideration. The answer could be any of the following (or something quite different):
- y approaches a specific value
- y approaches positive or negative infinity
- y is undefined
If you have 5x+3=48
takeaway 3 from both sides which leaves you with5x=45 then divide both sides by 5 which is
x=9

∫ f'(x)/(p2 + q2f(x)2) dx = [1/(pq)]arctan(qf(x)/p)
What is the answer to 5.60 x 6.40 x 2.20 x 2.15 x 2.10 x 1.90?
20.35 ! Just add them all together in your head - it's not rocket science !
