How do you use inqualities?
If an inequality is multiplied or divided by a negative number then the inequality sign is switched. For example, -2x > 4 then -2x/-2 > 4/-2 then x < -2.
What is the Oxidation state of Pb in PbO2?
O=-2 Pb=x x+(-2)*2=0 x+4-=0 -4+4=0 Pb4-
Find the sulotion set of 4a2-16a equals 0?
There are two answers in the solution set. To solve this we factor the left side to become 4a(a-4). This lets us get the 4. The other answers is 0. Set 4a=0 and solve for "a" and then a-4=0 and solve for "a."
Is a 2 percent salt solution hypertonic or hypotonic to a 4 percent salt solution?
hypotonic
What solution is C7H11NO7S?
4-nitro-2-toluenesulfonic acid dihydrate.
What is the solution of the equation x2-2x plus 4 equals 0?
If you mean to say (x^2)-2x+4=0 then there is no solution for x because the equation never makes it to 0 If you mean to say 2x-2x+4=0 then there is no solution for x because it is a horizontal line at Y=4
Is (2 0) a solution of 2x - y 4?
Yes, because if you sub in for x and y, you get 4-0=4 and this is true
What is the solution to this problem -2x - 2 equals 4?
-2x - 2 = 4-2x = 4 + 2-2x = 6x = 6/-2x = -3Check:-2(-3) - 2 = 46 - 2 = 44 = 4
What is the solution of 4 plus 2x equals 4?
x = 0
Which number is a solution of -2x -4?
If you mean: -2x = -4 then the value of x is 2
What are the coordinates for 2x-y-4?
If you mean: 2x-y = -4 then they are at (-2, 0) and (0, 4)
What are the points of intersection of the parabolas y equals x squared -2x plus 4 and y equals 2x squared -4x plus 4?
If: y = x^2 -2x +4 and y = 2x^2 -4x +4 Then: 2x^2 -4x +4 = x^2 -2x +4 Transposing terms: x^2 -2x = 0 Factorizing: (x-2)(x+0) => x = 2 or x = 0 Therefore by substitution points of intersect are at: (2, 4) and (0, 4)
How do you find the solution of 2x equals 4?
Divide both sides by two. x = 2 2x=4 2x/2=4/2 2x/2=1x=x 4/2=2 x=2
Does y equals 2x - 4 and y equals 2x - 5 have a common solution?
y=2x-4 y=2x-5 y=1 1=2x-4 -2x = -5 x=2/5 the solution is (x,y) = (2/5,1)
What is the solution to the inequality 4(2x plus 2) plus 12 and gt 1004(2x plus 2) plus 12 and gt 100?
There is no solution to: 4(2x + 2) + 12 > 1004(2x + 2) + 12 > 100 For 4(2x + 2) + 12 > 1004(2x + 2) + 12 to have a solution x < -1 which makes 1004(2x + 2) + 12 < 12, BUT 1004(2x + 2) + 12 is supposed to be greater than 100. Perhaps there is a missing operator in the digits of 1004?
Is x equals 4 for the problem 2x plus 4 equals 0?
Nope. In this case, x would be equal to -2. Here's how you can work it out: Given: 2x + 4 = 0 Subtract four from both sides of the equation: 2x + 4 - 4 = 0 - 4 2x = -4 Now divide both sides by two: 2x / 2 = -4 / 2 x = -2
What are the zeros in the function of 2X squared plus 3X -20 equals zero?
2x^2 + 3x - 20 = 0 is 2x^2 + 8x - 5x -20 = 0 is 2x(x + 4) -5(x + 4) = 0 is (2x - 5)(x +4) = 0 Hence 2x -5 = 0 which gives x = 2.5 or x + 4 = 0 which gives x = -4
