Answer:
13. She will have saved 1020 in 12 months and 467.5 in 11. 14. In 1 month she'll have saved 42.5 in 1 month and 212.5 in 5 months. 15. in 3 months she'll save 125 and 190 in 4 months. 16. The rate of change is 42.5. 17. It depends on your thoughts on what was more challenging, and knowing the rate of change can tell you half of certain amounts of money earned or what the difference between her earning months are. 18. I have no idea the y intercept someone else might be able to help you with that though. 19. I don't know that either someone else might help better.

Answer:
F = 9 / 5 * 20 + 32 = 9 * 4 + 32 = 68 deg F
Step-by-step explanation:
Answer: SR ≅ UT
Step-by-step explanation:
Process of elimination:
1) RT ≅ TR doesn't help because RT and TR are the same line.
2) RU ⊥ TU doesn't help prove that ΔRST ≅ ΔTUR. It only proves that ∠TUR is a right angle (which is already given).
3) SR ⊥ ST also doesn't help prove that ΔRST ≅ ΔTUR. It only proves that ∠RST is a right angle (which is already given).
4) The statement that SR ≅ UT tells us that ΔRST and ΔTUR are right triangles and have a hypotenuse and leg in common (both triangles share a hypotenuse, RT, both triangles have a 90 degree angle, and SR ≅ UT). If SR ≅ UT, we can prove ΔRST ≅ ΔTUR by using the HL triangle congruence theorem.
