How do you factor 4x2 -y2-6y-9?
It is (2x +y + 3)*(2x - y - 3).
How do you factorise 2xy - 6x plus 7y -21?
2x(y - 3) + 7(y - 3) = (2x + 7)(y - 3)
2x equals 3-y 2y equals 12-x?
2x=3-y 2y=12-x y=3-2x 2(3-2x)=12-x 6-4x=12-x -3x=6 x=-2 2(-2)=3-y -4=3-y y=7 x=-2 y=7
What is the x and y intercepts for 2x plus y equals -6?
-4
Are lines y equals 2x and y - 2x equals 3 perpendicular or parallel?
y-2x=3 -y -y -2x=3-y -3 -3 -2x-3=-y /-1 /-1 2x+3=y y=2x and y=2x+3 have the same slope of 2, so they are parallel. Hope this helps! ;D
Geometry linear y equals 2x-3?
y= 2x-3 when y=0 2x=3 x=1.5
What does x equal if y 2x 5?
y=2x-3 y=-x-3
X plus y equals 3 and y equals 3 - 2x?
x+y=3 y=3-2x so x+3-2x=3 so x=0 0+y=3 so y=3
Find the slope and the y-intercept what linear equation. Then graph 2x plus y equals -3?
2x plus y = -3 (subtract 2x from both sides) y = -2x - 3 slope = -2 y-intercept = -3
What is the inverse of y equals 2x plus 3?
I presume you mean given y find x: Make x the subject: y = 2x + 3 => 2x + 3 = y => 2x = y - 3 => x = (y - 3)/2 which can also be expressed as: x = 0.5 y - 1.5
Why there is minus sign in formula of y intercept?
If y = 2x+3 then the y intercept at is 3 on the y axis but if y = 2x-3 then the y intercept is at -3 on the y axis
What type of lines are these y 2x and y - 2x 3?

What is Y equals -2x plus 3 value of x is -3?
y = 9 -------- y = -2x + 3 x = -3 y = (-2)(-3) + 3 y = 6 + 3 y = 9
What is y-2x plus 3 equals 0 in standard form?
It is: y = 2x-3
How do you factor 4x2 -y2-6y-9?
It is (2x +y + 3)*(2x - y - 3).
Are lines y equals 2x and y 2x equals 3 perpendicular or parallel?
If the second equation is: y minus 2x equals 3, then:y - 2x = 3 ⇒ y = 2x + 3 and it is parallel to y = 2x.Otherwise (with with missing operator as "plus", "multiply" or "divide"), the lines are neither parallel nor perpendicular.
