two step equations variables

Find a value of the variable x for which the value of x 2 + 3x - 4 is equal to 0. Let x =1, Then, f(1) = (1) 2 + 3(1) - 4 = 0..

We have the following conditions on the variables x and y. a) Sum of the numbers is atleast 15 i.e., x + y 15 b) Difference of the numbers is at most 7 i.e., x - y 7 c) Since the x and y should be positive, we have two more conditions x > 0, y > 0 We call Z as objectiv..

The first 2 electrons will go to the 1 s t shell = K Shell (2n 2 ) The next shell L takes a maximum of 8 electrons (2n 2 ). In this way 2 + 8 = 10 electrons have been accommodated. The next 2 electrons go to the M Shell..

Find the co-ordinates of each vertex of the feasible region. These co-ordinates can be obtained from the graph or by solving the equation of the line..

>(ii) The oxidation number of chromium on the left is +6 and on the right is +3. Each chromium atom must gain three electrons. Since there are two Cr atoms, add 6e - on the left. (iii) Since the reaction takes place in acidic medium add 14H + on the left to equate the net charge..
