The inverse variation xy = 100 relates the constant speed x in mi/h to the time y in hours that a car takes to travel 100 miles. Use the graph to estimate the number of hours the car would take to travel 100 miles at a speed of 20

Circle a has center of (2,3) and a radius of 5 and circle b has a center of (1,4) and a radius of 10. what steps will show that circle a is similar to circle b 1) dilate circle a by a scale factor of 2 2) translate circle a using the rule (x+1,y-1) 3) rotate circle a 180 degrees about the center 4) reflect circle a over the y-axis
