Step-by-step explanation:

arithmetic operations in functions are simple : you take both expressions and apply the arithmetic operation on them.

in our case : addition.

f(x) = 4x² + 5x - 3

g(x) = 4x³ - 3x² + 5

(f+g)(x) = (4x² + 5x - 3) + (4x³ - 3x² + 5) =

= 4x² + 5x - 3 + 4x³ - 3x² + 5 =

= 4x³ + x² + 5x + 2

so, B should be the right answer (despite all the typos there).

4 What is the solution to the inequality -3x-42>3 ?

Vladimir [108]

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

What is the solution to the inequality -3x-42>3 ?

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$- 3 x - 42 \gt 3$

Add 42 to both sides.

$-3x>3+42$

Add 3 and 42 to get 45.

$-3x>45$

Divide both sides by -3. As -3 is <0, the inequality direction has changed.

$x$

Divide 45 by -3 to get -15.

Ilia_Sergeevich [38]

3x = B
(x + 80 = 1/2B) * -3
-3x-240 = -3/2B

-240 = -1/2B
B=480 pennies
