the idea being, you multiply the "x" by some power of 10 that moves the repeating part to the left of the decimal point and the split it like above.
13xy^2-10xy-23=0
you first add the like terms and rewrite and thats how you get the answer
All you have to do for this is plug in each coordinate point to the function. Ex. (0,2). Plug in 0 to the “x” part of the function, and solve that side; you will get 2. Then you plug in 2 in this case for “y”. You will end up with 2<2 which is a FALSE statement. And you keep doing that until you get a TRUE statement.
Yes it is a even number because the numbers that add up may equal the equal number if that answer is correct
15% = 0.15
15% of 71.85 is equal 0.15*71.85 ≈ 10.78
