-2x2
x = 15
a negative number plus a negative number is negative. here is a proof.(-x)+(-x)(-1)x+(-1)x-1(x+x)-1(2x)-2xa negative number times a negative number is positive though.
x+x=2x
change the y value to -y, and bring the negative over the equal sign. example. y=2x^2 reflected on the x-axis looks like y=(2x^2)/-1 which is equal to y=-(2x^2)
"minus negative x" means "plus x" (2x - 5)(x + 2) or (2x + 5)(x - 2) depending on what you really meant...
2x + x = -27 3x = -27 3x/3 = -27/3 x = -9
x = 15
a negative number plus a negative number is negative. here is a proof.(-x)+(-x)(-1)x+(-1)x-1(x+x)-1(2x)-2xa negative number times a negative number is positive though.
x+x=2x
It is: -2x squared
No.If 'x' is negative, then ( x + |x| ) = 0.If 'x' is positive, then ( x + |x| ) = 2x.
2x minus 3x is equal to -x.
When x = -3
change the y value to -y, and bring the negative over the equal sign. example. y=2x^2 reflected on the x-axis looks like y=(2x^2)/-1 which is equal to y=-(2x^2)
"minus negative x" means "plus x" (2x - 5)(x + 2) or (2x + 5)(x - 2) depending on what you really meant...
When x is equal to 10, the value of 1/2x is 5.
I believe the converse is: if 2x equals 6 then x equals 3 inverse: if x doesn't equal 3 then 2x doesn't equal 6 contrapositive: if 2x doesn't equal 6 then x doesn't equal 3
