Mary has $33. She wants to buy a book that cost $53 and will save $5 per week. How many weeks will it take for her to have enough for her book?

4 weeks

Step-by-step explanation:

if she starts with $33, and she gets $5 per week, and she need $53, then you would add $5 starting at $33 until you reach the book price of $53. Or you could subtract $33 from $53 and then divide that answer by $5.

First time answering a question so i hope i helped :)

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
