Answer:
(56/45)x^7
Step-by-step explanation:
28x^4 20
---------- ÷ ----------- becomes
27 24x^3
28x^4 24x^3
---------- * ----------- if we invert the divisor fraction and then multiply.
27 20
We get: (28)(24)
-------------- x^7
(27)(20)
which reduces to (7)(24) x^7 (7)(8)x^7
--------------- = ------------- = (56/45)x^7
27(5) 9(5)
Answer: The first graph is the right graph according to the given situation.
Step-by-step explanation:
Given: Becky created a graph to represent her distance away from home one afternoon.
She left home and ran to the park⇒ She started running from zero distance from the home .⇒the second and fourth graphs are wrong .
After that she met some friends and stayed at the park, then walked back home using the same route.⇒ The first one is correct because there we can see the graph is parallel to time axis for a interval but in the third one it shows that she she hasn't took rest .
It’s going to be the second one. B
