Gordon and tess are trying to determine whether triangle abc and triangle fge can be proven congruent through rigid motions.

gordon says that triangle abc ~= triangle fge because triangle abc can be reflected over the line x = 1 to create triangle fge.

tess says that triangle abc ~= triangle fge because triangle abc can be translated by the rule (x + 5, y - 7) to create triangle fge.

who is correct?

Cody started biking to the park traveling 15 mph, after some time the bike got a flat so cody walked the rest of the way, traveling 4 mph. if the total trip to the park took 6 hours and it was 46 miles away, how long did cody travel at each speed? solve using rate times time= distance

Ariana starts with 100 milligrams of a radioactive substance. the amount of the substance decreases by 20% each week for a number of weeks, w. the expression 100(1−0.2)w finds the amount of radioactive substance remaining after w weeks. which statement about this expression is true? a) it is the difference between the initial amount and the percent decrease. b) it is the difference between the initial amount and the decay factor after w weeks. c) it is the initial amount raised to the decay factor after w weeks. d) it is the product of the initial amount and the decay factor after w weeks.
