Solve each equation for the variable. If the values are not integers, please record in decimal format to the nearest tenth.

-21 = -7x +12 (subtract 12 from both sides)

-33 =-7x (divide each side by negative 7)

x= 4.71428571 (round your answer to 4.7 )

i dont know sorry

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
