Marta’s math textbook weighs Four-fifths of a pound less than 4 times the weight of the book she is reading for her language arts class. If the weight of the math textbook is 2 and one-fifth pounds, which shows the correct equation and value of x, the weight of Marta’s book for language arts? 4 x + four-fifths = 2 and one-fifth; x = StartFraction 7 over 20 EndFraction of a pound 4 x minus four-fifths = 2 and one-fifth; x = three-fourths of a pound 4 x + four-fifths = 2 and one-fifth; x = three-fourths of a pound 4 x minus four-fifths = 2 and one-fifth; x = StartFraction 7 over 20 EndFraction of a pound

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

its line 2 i just added the rest or else it wouldn't let me answer

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
