Mrs. fox math class earned a popcorn party for completing all homework for three weeks. Mrs Fox's job was to bring the popcorn and all other supplies, they needed 5 cups of unpopped
popcorn to make the perfect amount of popcom for the whole class. She brought the bag of
popcorn but she forgot to bring the measuring cups. However, she had 2 other containers, one
was a 7 cup container and the other was a 3 cup container. How could the class use these two
containers to measure exactly 5 cups of popcorn?
Process: (Write about all the things you did to solve the problem.)

f(x)=2/3x-8, which give g(x) the greatest value.

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
