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.
What is the answer to 3x plus 11 equals -25-9x?
Add 9x to each side: 12x + 11 = -25
Subtract 11 from each side: 12x = -36
Divide each side by 12: x = -3
X+2X2+4= just that. can't be simplified.
however...
X+2X+4= 3X+4
errr, is that what you meant?
It is quarilateral with one pair of parallel sizes?
A quadrilateral with one pair of parallel sides is a trapezoid.
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.
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.
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
Find the possible value of z in the quadratic equation z squared -4z plus 4 equals 0?
z = 2
Factorised as (z - 2)(z - 2) = 0
X squared plus nine x plus eleven divided by x plus seven?
are you sure from this equation ?
x^2 + 9x + 11
____________ = zero
x + 7
or there is no zero ??
please be sure from the x^2 + 9x + 11 ???
What is the function of the BKF?
If you mean Microsoft's backup file extension, it's function is to make PCs and Macs even more incompatible, thus putting more money into Bill Gates' pocket.
What will be the answer of this (956 - 830) x (908 x 291 plus 598)?
(956 - 830) x (908 x 291 + 598) =
(126) x (264228 + 598) = 33368076
1.5/6.5 = 3/13 and 6.5/1.5 = 13/3
The equation is : 39x2 - 178x + 39 = 0
x = {-(-178) ± sqrt[(-178)2 - 4*(39)*(39)]}/(2*39)
= {178 ± sqrt[25600]}/78
= {178 ± 160}/78
= 18/78 or 338/78
= 3/13 or 13/3, as required.
----
This is what I would add, although it might be unnecessary:
As Mehtamatics indicates the solutions are 3/13 and 13/3. This implies that the equation can be written as the product of factors ( x - 3/13 ) and ( x - 13/3 ).
( x - 3/13 )( x - 13/3 )
= x2 - ( 39 + 169 ) x / 39 + ( 3/13 ) ( 13/3 )
= x2 - 178 x / 39 + 1
= 39 x2 - 178 x + 39 = 0
The required condition is a*b ≠0. That is equivalent to the requirement that neither a nor b is 0.
