We are given the expression f(x) = 40x where f(x) is the dependent variable and x is the independent variable. In this case, we can see that f(x) is directly proportional to x and that the constant of propotionality is 40. Answer then to this problem is D. 40

$\text{Quadratic formula}$

$ax^2+bx+c=0\\\\\Delta=b^2-4ac\\\\x_1=\dfrac{-b-\sqrt\Delta}{2a};\ x_2=\dfrac{-b+\sqrt\Delta}{2a}$

-----------------------------------------------------------------------

$x^2+3x+9=0\\\\a=1;\ b=3;\ c=9\\\\\Delta=3^2-4(1)(9)=9-36=-27\\\\\sqrt\Delta=\sqrt{-27}=\sqrt{(27)(-1)}=\sqrt{27}\cdot\sqrt{-1}=\sqrt{9\cdot3}i=\sqrt9\cdot\sqrt3i=3\sqrt3i$

$x_1=\dfrac{-3-3\sqrt3i}{2(1)}=-\dfrac{3}{2}-\dfrac{3\sqrt3}{2}i\\\\x_2=\dfrac{-3+3\sqrt3i}{2(1)}=-\dfrac{3}{2}+\dfrac{3\sqrt3}{2}i$

$i=\sqrt{-1}$

Answer:

A

Step-by-step explanation:

Given the 2 equations

x = 3 - y → (1)

5x - 12 = y → (2)

Substitute x = 3 - y into (2)

5(3 - y) - 12 = y ← distribute and simplify left side

15 - 5y - 12 = y

3 - 5y = y ( add 5y to both sides )

3 = 6y ( divide both sides by 6 )

$\frac{3}{6}$ = y, that is

y = 0.5 → A
