Construct a graph corresponding to the linear equation y equals 2x - 6?
-4
To find critical points?
Take the derivative of the function and set it equal to zero. The solution(s) are your critical points.
How do you solve a simultaneous equation with 3 variables?
You cannot have a simultaneous equation: you must have 2 or more equations for there to be any simultaneity.The simplest method to solve them is to invert the matrix of coefficients but this requires you to know matrix algebra and the question suggests tha you are not that advanced.In that case, express any one of the variables in terms of the other two. Substitute the resulting expression in the other equation(s). Repeat until you have only one variable. Find its value and substitute in the previous equation. That will then enable you to find a second variable. And so on.
What is the graph of a function when it has no gaps or holes?
It is a continuous line whose shape depends upon what expression it is meant to represent.The equation y = x would be a straight line passing through (0,0) and all the other points where the x and y co-ordinates were equal, including negative ones such as (-11,-11).But if the equation has x squared in it the shape would be a parabola, while the graph of an equation with y cubed in it would have something like an S shape in it. More complex equations could produce many differently shaped lines.
How do you solve 2mn-2mt plus 2sn-2st equals 0?
2mn - 2mt + 2sn - 2st = 0Divide both sides of the equation by 2:mn - mt + sn - st = 0m (n - t) +s (n - t) = 0(m + s) (n - t) = 0That's as far as you can go with the information given.
If the discriminant is negative the graph of a quadratic function will cross or touch the x-axis time s?
If the discriminant is negative, the equation has no real solution - in the graph, the parabola won't cross the x-axis.
What is the meaning of solution of an equation?
The solution to an equation consists of the value (or values) of all the variables such that the equation is true when the variable(s) take those values.
The ordered pair 2 16 is a solution for which equation s?
7-4-14
What is the net ionic equation for silver nitrate solution and potassium iodide solution?
The chemical equation is: (K+ + I-)(aq) + (Ag+ + [NO3]-)(aq) --> AgI (s) + (K+ + [NO3]-)(aq) or The chemical equation is: K+I- (aq) + Ag+[NO3]- (aq) --> AgI (s) + K+[NO3]- (aq)
What is the correct balanced reaction equation that shows the chemical reaction of aqueous solution lead II nitrate mixed with an aqueous solution of potassium sulfate Also the total ionic equation?
The complete balanced equation is Pb(NO3)2 (aq) + K2SO4 (aq) -> 2 KNO3 (aq) + PbSO4 (s). The total ionic equation is Pb+2 (aq) + SO4-2 -> PbSO4 (s).
What is the discriminant of the polynomial 2x2 4x-9?
b2 - 4ac (whatever that 4's sign is it is positive when squared ) (4)2 - 4(2)(- 9) 16 + 72 = 88 ===============Two real roots.
What is the ionic equation for Lead ions can be removed from solution by precipitation with sulfate ions Suppose a solution contains lead nitrate?
The ionic equation would usually be written as: Pb+2 (aq) + SO4-2 (aq) -> PbSO4 (s)
Will a double replacement reaction occur if a potassium hydroxide solution is mixed with a lead(II) nitrate solution if so write a net ionic equation for the reaction?
The chemical equation is:2 (OH)- + Pb(2+) = PbOH)2(s)
Will a double replacement reaction occur if a potassium hydroxide solution is mixed with a lead (II) nitrate solution if so write a net ionic equation for the reaction?
The chemical equation is:2 (OH)- + Pb(2+) = PbOH)2(s)

What has the author S Vadera written?
S. Vadera has written: 'Learning after trees by incorporating linear discriminant analysis'
How do you write a balanced equation for FeCl3 and Na2S)?
1. Add a small quantity of the FeCl3 solution into the Na2S(aq.). 2FeCl3+3Na2S=2FeS↓+6NaCl+S↓ the following is the ionic reaction equation 2Fe3+ + S2- = 2FeS↓+ S↓ 2. Add a small quantity of the Na2S solution into the FeCl3(aq.) 2FeCl3 + Na2S =2FeCl2 + 2NaCl + S↓ the following is the ionic reaction equation 2Fe3+ + S2- = S↓ + 2Fe2+
