The square of a whole number is between 2000 and 2500. the number much be a. 30 & 35 b. 35 & 40 c. 40 & 45 d. 45 & 50

D is the correct choice.

Step-by-step explanation:

30^2 = 900, which is less than 2000 and thus too small.  Reject choice A.

35^2 = 1225, which is less than 2000 and thus too small.  Reject choice B.

40^2 = 1600, less than 2000.  Reject choice C.

45^2 = 2025, which is greater than 2000 but less than 2500.  This is the correct choice.  D is correct.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.
