The graph shows the relationship between the weight of a box and the number of books added to the box. A graph shows number of books labeled 1 to 10 on the horizontal axis and weight of box (pounds) on the vertical axis. A line increases from 1 to 6.

What function represents the weight of a box based on x, the number of books?

f(x) = 0.5x + 1.5
f(x) = 0.75x + 2
f(x) = 1.5x + 0.5
f(x) = 2x + 0.75

step-by-step explanation:

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n

\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example,  57=112−82=292−28257=112−82=292−282.

\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.

can i get some in proving questions 1 and 2?
