Mathew reads equal numbers of pages of a book every week. The graph shows the number of pages of the book left to read, y, after x weeks: Which equation best models the relationship between x and y? (1 point)
A. y = −30x + 150
B. y = −5x + 30
C. y = −30x + 210
D. y = −5x + 150

y=-30x+150

Step-by-step explanation:

3, 12, 48, 384, 1536, 6144, 24576, 98304

step-by-step explanation:

just keep timing it by 4.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
