Your friend prints a 4-inch by 6- inch photo for you from the school dance. all you have is an 6-inch by 8- inch frame. can you dilate the photo to fit the frame?

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
