Does y equals 2 x plus 3 mean 3 units up?
In a sence it does; it means 3 units up on the y-axis, which is the point at which it crosses the y-axis.
What is y plus 3?
In mathematics, "y plus 3" is an algebraic expression representing the sum of a variable 'y' and the constant 3. This expression cannot be simplified further unless the value of 'y' is known. If 'y' is a known value, then the sum can be calculated by adding 3 to that value. If 'y' is unknown, then the expression "y + 3" remains as is, representing a sum of 'y' and 3.
What is a -y-y-y-y-y-y-y?
means y ????????
Y equals 1 plus 3x and y equals 16-2x What is X and Y?
y = 1 + 3x y = 16 - 2x Because y = y, that means... 1 + 3x = 16 - 2x Solve for x... x = 3 Plug it back in to one of the original equations... Y = 1 + 3(3) = 10 So... x = 3 y = 10
X2 plus y2 equals 13 where y equals 2?
If y=2 then that means x^2=9 and x= 3 or -3
