Ireally need on this, i don't quite understand what i am doing : .)

factor and show work

f ( x ) = 9 x 3 + 2 x 2 − 5 x + 4
g ( x ) = 5 x 3 − 7 x + 4
what is f ( x ) − g ( x ) ?

Subtract the two equations

f(x) - g(x)

(9x3 + 2x2 - 5x + 4) - (5x3 - 7x + 4)

9x3 + 2x2 - 5x + 4 - 5x3 + 7x - 4

4x3 + 2x2 + 2x

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

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 !
