The domain and range of an equation are the values of x and y that will make the equation true or make the equation possible to solve. The given equation is an equation of a circle. The values of x and y that would make this equation possible to solve ranges from negative to positive values. If we take y as zero, x values can range from negative 5 to positive 5. If we take x as zero, y values can range from -5/3 to 5/3.

Answer:

x = 6

Step-by-step explanation:

first you would put them equal because they have the same angle: 9x + 10 = 2x + 52

subtract 10 from both sides: 9x = 2x + 42

subtract 2x from both sides: 7x = 42

divide by 7 on both sides x = 6

hope this helps! :)
