It is impossible to answer the question without some information about V or t or what the equation is meant to represent.
X2 = k Take square root each side. X = (+/-) sqrt(k) ============
31 = 3-4k 31-3 = -4k 28 = -4k Divide both sides of the equation by -4 to find the value of k: k = -7
Using the discriminant the possible values of k are -9 or 9
Using the discriminant of b^2 -4ac = 0 the value of k works out as -2
K = 6
k equals 5.6
The equation -k =287.658 just gives k = -287.658
k is the variable.
I am supposing you are looking for k, in that case you add 4.05 to both sides of the equation to cancel out the 4.05 on the k side, making the equation k = 10.25
For the equation x2- 10x - k equals 0, you can solve this by knowing that if there is only one solution then the discriminant b2 - 4ac must be equal to 0. In this equation, a is 1, b is 10 and c is k This equation becomes 100 - 4k equals 0, and k is 25.
p = k/v or pv = k k is a constant p is pressure v is volume
k = sqrt(160) = 12.6
It is an equation. Taking it step by step: 37 - k = 17 -k = 17 - 37 -k = -20 k = 20
T/oC = T/K - 273.15
You cannot go beyond x = k unless you know the value of k. And in that case, the equation is solved so there is nothing further to do!
It represents an algebraic equation in the variable, k.
It is a linear equation in the variable r.
