What is the inverse function of y equals -x-5?
This was on my test yesterday . . .it's really easy, just put a one over the -x-5.
How do you solve this problem 7x - 3 - 2x equals 17?
7x - 3 - 2x = 17
-2 -2
7x - 3 - x = 15
-7 -7
x - 3 - x = 8
+3 +3
x - x = 11
+x +x
x=11x
-x -x
(x=) 11
does that look familiar from class? You can do it different ways...
* * * * *
Yes, you can do it the correct way, instead!
7x - 3 - 2x = 17
Combine the like terms (7x and -2x) on the left side: 5x - 3 = 17
Add 3 to both sides: 5x = 20
Divide both sides by 5: x = 4
Check:
7*4 - 3 - 2*4 = 28 - 3 - 8 = 28 - 11 = 17
Does not work with x = 11!
What is A equation for -2x plus 8 equals 7x-10?
-2x + 8 = 7x - 10 is technically an equation, in and of itself.
What is the domain and range of the equation x² plus y² equals 36?
The domain and range are both [-6, +6].
It is correct to write it any way you like.
However, when dealing with equations it is usual to give the dependent variable (usually y) first; if it is unknown which variable is the dependent one (or for any general expression), they are usually written in alphabetical order.
How do you solve 22-7x equals 0?
22 - 7x = 0 /+7x
22 = 7x /divide by 7
x = 22/7 = 3 1/7
22/7 is your more formal answer, that's pertaining what's asked for the question, is it to answered as a mixed fraction, or improper fraction.
How do you make the left the same as the right for tan 0 times cot 0 all over tan 0 csc2 0?
You cannot because cot(0) is not defined, neither is cosec(0).
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. Also use ^ to indicate powers (eg x-squared = x^2).
It would appear that some symbols are missing: for example, between y and x-y. Second, the equations, such as there are, are not mutually consistent.
Can you give me area of a quadrilateral with sides measuring 197 x 39 x 196 x 42?
Not without knowing at least one of the angles.
You would need to know at least two of the angles (preferably opposite angles) then use Brahmagupta's formula.
How is being good at mathematics going to help you with physics chemistry and engineering?
Because the majority of economics, physics and engineering and general chemistry requires you to be able to calculate, not just learning concepts.
Since the base is unspecified, it is taken to be 10 and log(580) = 2.7634 approx.

How many 0 do you put when you divide by ten?
only one and it depends if you got more zeroes in the number like 100, 1000, 10000 as many as the number has....!!!
