Write a function for number 1, to express the price in terms of the number of ounces in a can. Hint: 2 points are given to you. so find the slope by finding change in y values over change in x values (remember cents are written using decimals). Then find b by substituting in values for y, m, & x and solve for b (y=mx+b)
Your slope and y-intercept will be in decimals.

45.3592

step-by-step explanation:

21

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
