8 4/100 = 8.04, as the ".00" is out of 1.00. 4/10 = 0.40 4 7/100 = 4.07 6/10 = 0.60 8 3/100 = 8.03 8/10 = 0.80 4/100 = 0.04 10 14/100 = 10.14 The quick way to determine what the decimal is, is to divide 100 by the denominator. That way, each time the numerator goes up, you can multiply how many times it goes up by the denominator. I hope this helps!
7 x² + 7 y² - 28 x + 42 y - 35 = 0 /: 7 x² + y² - 4 x + 6 y - 5 = 0 ( x² - 4 x + 4 ) + ( y² + 6 y + 9 ) - 4 - 9 - 5 = 0 The equation in the standard form is: ( x - 2 )² + ( y + 3 )² = 18 The center is at the point ( 2, - 3 ). Its radius is: √18 = 3√2 units.
