Express your answer as a polynomial in standard form. f(x) = -x + 3 g(x) = 2x^2 – 3x - 7 Find: f(g(x))

-2x² + 3x + 10

Step-by-step explanation:

-(2x² - 3x - 7) + 3

-2x² + 3x + 7 + 3

-2x² + 3x + 10

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
