What is the value of the expression 4x-2y plus xy when x equals -1and y equals 5?
To find the value of the expression 4x - 2y + xy when x = -1 and y = 5, we first substitute the values of x and y into the expression. This gives us 4(-1) - 2(5) + (-1)(5). Simplifying this further, we get -4 - 10 - 5, which equals -19. Therefore, the value of the expression is -19 when x = -1 and y = 5.
If x equals 5 and y equals 5 then 8x plus 4y equals?
(8 + 4) x 5...
What are the values of x in this quadratic equation 2x squared-x-5 equals 0?
2x2 - x - 5 = 0 x = [1 +/- sqrt(1 + 40)]/4 = [1 +/- sqrt(41)]/4 = -1.35078 and 1.85078
Is point 1 4 on the line represented by the equation x plus 2y equals 5?
The equation "x plus 2y equals 5" is: x + 2y = 5 2y = 5 - x y = 5/2 - 1/2x y = -1/2x + 5/2
X varies directly with y and inversely with z x equals 125 when y equals 5 and z equals 4 Find x when y equals 4 and z equals 5?
Given x=k1y and x=k2/z x=125 ,y=5 then k1=25 x=125 , z=4 then k2=125(4)=500 If y=4 ,z=5 then x=25y = 100
X plus y equals 5 let x equals 4?
If X+Y=5;X=4, then x=4 and y=1
X plus 4 divided by x equals 5?
9
X minus 4 equals 1 What is x?
x - 4 = 1 4 + 1 = x Therefore, x = 5
What is X plus 1 equals 5?
x=4
How do you solve ln 5 plus ln x equals 1?
5 + (-4) = 1 x = -4
What is 5 x 1?
x(x + 1) = x**2 + x
What is x over 4 plus 5 equals negative one?
x/4 + 5 = -1 (4)x/4 +(4)5 = -1 x+20 = -1 -20 -20 x= -21 x= -21
What is -4 plus 5-2x when x equals 1?
-4+5-2 = -1
What is -5 equals x-4?
-1
What does 8x equals 10 equals?
x = 10/8 or 5/4 or 1 and 1/4 or 1.25
2x plus 5 equals 3x plus 1?
2x+5=3x+1 -x=-4 x=4
If 3x plus 9 equals 5 what is x?
Well if 3x+9=5 x=? Well you minus 9 from the side and then do 5-9 and that equals -4. Then you have to do -4 divided by 3. Which equals -1 so I believe x will equal -1.
