A car travelled 216km at an average speed of 48km/h. On the return journey the average speed increased to 72km/h. Calculate the average speed, in km/h for the whole journey

Write an equation in point-slope form for the line through the given point that has the given slope (-2,-7); m=-3/2

Can someone me with these two circle theorem questions asap?

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
