Sabrina is using an online calculator to calculate the outputs f(n) for different inputs n. the ordered pairs below show sabrina's inputs and the corresponding outputs displayed by the calculator:
(1,6), (2,11), (3,16), (4,21)

which of the following functions best represents the rule that the calculator used to display the outputs?

a) f(n)= 5n-1

b) f(n)= 5n+1

c) f(n)= 4n+3

d) f(n)= 4n-3

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
