The cost of sending cell phone picture is given by y=0.5x, where x is the number of pictures that you send and y is the cost in dollars. a. Write the equation in function notation. interpret the function in terms of the context.
b. Find f(5) and f(12). What do these values represent?
c. Determine the domain and range of this function.

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are

simplifying

7ln(x + 2.8) = 11.2

reorder the terms:

7ln(2.8 + x) = 11.2

(2.8 * 7ln + x * 7ln) = 11.2

(19.6ln + 7lnx) = 11.2

solving

19.6ln + 7lnx = 11.2

solving for variable 'l'.

move all terms containing l to the left, all other terms to the right.

reorder the terms:

-11.2 + 19.6ln + 7lnx = 11.2 + -11.2

combine like terms: 11.2 + -11.2 = 0.0

-11.2 + 19.6ln + 7lnx = 0.0

the solution to this equation could not be determined.

step-by-step explanation:

i searched it on google but it says that the solution to this equation could not be determined but i hope that it you a little.

answer: there are a lot of coordinates some are (3,0) or (0,1)
