What is x if x 2y 10 and y 3?
If you mean: x+2y = 10 then if y = 3 then x = 4
Which type of lines are these y2x and 2y-x plus 4?
If you mean: y = 2x and 2y = -x+4 then they are positive and negative straight line equations
What is the x intercept of 5x - 2y 20?
Assuming you meant 5x-2y=20... 5x - 2(0) = 20 5x = 20 x = 4 X-intercept is 4
Simplify 3x plus 2y plus 2 equals 4y plus 4?
The equation can be simplified to show a value of Y in terms of X. 3X + 2Y +2 = 4Y + 4 3X + 2 = 2Y + 4 3X -2 = 2Y and 2Y = 3X - 2 means that Y = (3/2 X) -1
Is a number divisible by 4 always even explain why?
if x is divisible by 4 then x/4 = y, where y is an integer. so it follows that y = x/(2*2) and therefore 2y = x /2. since y is an integer, so must 2y. since x/2 yields an integer (2y), x must be even.
