step 1: x - 9 = -30
step 2: x = -30 + 9
step 3: x = -21
How do you make x the subject when v x?
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).
One pair, 10z and -4z, since like terms are only terms that contain the same variable(s) with the same exponent.
What is AI Chatbot Integration?

23ftx17ftx27ftx8ft 8ft high what is this in square meters please?
It is impossible to answer the question. "23ftx17ftx27ftx8ft" is a measure in 4-dimensional hyperspace. If then, you add in a height, you have a "volume" in 5-dimensional space.
18=1,2,3,6,9,18
22=1,2,3,4,5,6,722 18=1,2,3,6,9,18
22=1,2,3,4,5,6,722
It is quarilateral with one pair of parallel sizes?
A quadrilateral with one pair of parallel sides is a trapezoid.
Under what circumstances would the domain be something other than all real numbers?
It would be an imaginary number (one that cannot exist). For example the square root of a negative number.
X+2X2+4= just that. can't be simplified.
however...
X+2X+4= 3X+4
errr, is that what you meant?
How do you rewrite equation T equals 101.3e to the H over 26200 power so that you solve for H?
T = 101.3 eH/26,200
eH/26,200 = T / 101.3
H/26,200 = ln(T/101.3)
H = 26,200 ln(T/101.3)
Whatever you want it to be. In mathematics, letters are used for "variables", placeholders for a number which is not specified. Sometimes you are supposed to find a value of "y" so that a certain equation is true. For example, if y + 5 = 8, the only correct value for y is 3. In another equation, "y" may have a different value.
2 perenthesis -2 perenthesis -3y equals 6?
2(-2)-3y=6 which is equal to -4 -3y = 6 which is equal to -3y = 10 which is equal to y = -(10 / 3) = -3.333...
If -1 equals x equals 2 and 1 equals y equals 3 then least value of 2y-3x is?
here for least value X=2,y=3
hence 2(3)-3(2)=0
=0
Which equation of the graph occurs when y equals x is changed to y equals x equals 2?
The diagonal line collapses into a single point on that line.
