They are equivalent. combine like terms on the first one and 9x-4x+25 can be simplified to 5x+25.
This is solved for all values of
y = -x-3. (Assuming you meant that 2x+2y=-6).
While a digit in the thousands place has a value 1,000 times the value of the digit. So to compare you can do 10,000 / 1,000 = 10, which means that a digit in the ten thousand place values ten times what the same digit values is it is the thousand place.
On a coordinate plane, a curve crosses the y- axis at (0,1). It has a minimum of negative 1 and a maximum of 1. It goes through 2 cycle at 2 pi.
See tha attached pdf file and let me know how useful this answer is.
