First you put the x in the side of the -2 and it will be like: y= -2 -x then you replace the y in the other equation for (-2 -x) will be: 2x -3(-2 -x)=-9 after you multiply -3 times -2 and -x and will give you this equation: 2x + 3x +6 = -9 and the sum de 2x and the 3x that equals 5x you subtract 6 from both sides and subtracted to -9 and this will be the equation 5x = -15 dived both sides by 5 and you will get x= -3
then you do the other equation using the y = -2 -x or 2x-3y=-9 but its more easy the first one so you will replace x for -3 y= -2 -(-3) and will get: y= -2 +3 because a subtract sing and a negative sing if they are together they form a positive sign and will get y=1 answer: (-3, 1)
Step-by-step explanation: We're just solving for the area of a circle. A = pi•r^2. The diameter is 16 which is 2r so r = 8. 8^2 • pi = 64pi = 201.06 (rounded to 2 decimals)
