What is the answer for 2x 1 7?
2x = 17 then x = 8.5 2x+1=7 then x = 3 2x - 1 = 7 then x = 4 which is your problem
How do you factor x2 2x-3?
x2 + 2x - 3 = (x + 3)(x - 1)
3X-4 all over 1- 2X-4?
If 3X - 4 ------ = 0 1-2X-4 So 3X - 4 ----- = 0 [ x (2X-3) ] 2X-3 3X-4 = 2X-3 [ -2X ] X - 4 = -3 [ +4 ] X= 1
How do you solve x equals 2x-1?
3
What is the value of x in 6x plus9 equals -3?
6x + 9 = -3 6x/3 + 9/3 = -3/3 2x + 3 = -1 2x + 3 - 3 = -1 - 3 2x = -4 2x/2 = -4/2 x = -2
What does x equal when x plus 3 bracket x plus 1 bracket equals 2x?
x+3(x+1)=2x x + 3x + 3 = 2x 2x + 3 = 0 2x = -3 or x = -1.5
What is the derivative of fx where fx equals 2x-3 all under square root?
f(x) = √(2x -3) f(x) = (2x - 3)^(1/2) f'(x) = (1/2)[(2x - 3)^(1/2 - 1)](2) f'(x) = (2x - 3)^(-1/2) f'(x) = 1/[(2x - 3)^(1/2)] f'(x) = 1/√(2x -3)
What is (2x plus 3) (x plus 1)?
(2x + 3)(x + 1 ) = 2x^2 +5x +3
What is the answer to 3 equals 2x plus 1?
x = 1 ------------- 3 = 2x + 1 -1 -1 2=2x /2 /2 1=x
X plus 2x plus 3?
This equals 3x+3 also written as 3(x+1). If you mean a linear equation like 3x + 3 = 0, then the solution is x = -1
What is the value of x if 2x squared -5x equals 3?
2x2 - 5x = 3 ∴ 2x2 - 5x - 3 = 0 ∴ 2x2 + x - 6x - 3 = 0 ∴ x(2x + 1) - 3(2x + 1) = 0 ∴ (x - 3)(2x + 1) = 0 ∴ x ∈ {-0.5, 3 }
What is the answer for 2x 1 7?
2x = 17 then x = 8.5 2x+1=7 then x = 3 2x - 1 = 7 then x = 4 which is your problem
The reciprocal of a number plus the reciprocal of twice the number equals one half?
Let the number be x.Reciprocal of x = 1/xReciprocal of x + Reciprocal of 2x = 1/x + 1/(2x) = (3/2)x = 1.5xIf the value of x = 1/3 then answer is one half.If the value of x = 2 then answer is 3.So, the statement is true only for x = 1/3.___________1/x + 1/2x = 1/2Multiplying both sides of the equation by 2x gives:2x/x + 2x/2x = 2x/2This simplifies to:2 + 1 = xx = 3 (i.e. the reciprocal is 1/3)
How do you factor x2 2x-3?
x2 + 2x - 3 = (x + 3)(x - 1)
What is 2x -6 and x - 4 3 equal to?
# ## 2x > -6 and x - 4 < 3 ## x + 3 > 2x + 1 and -4x < -8 ## -6 < x + 3 < 6 ## -3x > -6 or x - 5 < 2 ## x - 2 > 2x + 1 or 10 > -2x + 2
What is 2X plus X-3?
-1
What is the answer 2x2 plus 7x plus 3?
2x2 + 7x + 3 = (2x + 1)(x + 3)If 2x2 + 7x + 3 = 0 then:(2x + 1)(x + 3) = 0⇒ (2x + 1) = 0 → x = -1/2or (x + 3) = 0 → x = - 3
