f(x) = 2x - 6

g(x) = 3x + 9

(f + g)(x) is f(x) + g(x)

<u>Step 2: Find</u>

  1. Substitute in function values:                                                                          (f + g)(x) = 2x - 6 + 3x + 9
  2. Combine like terms:                                                                                         (f + g)(x) = 5x + 3

asambeis [7]

Answer:

4

Step-by-step explanation:

If two variables are proportional then

y\propto x

y=kx    ...(i)

where, k is constant of proportionality.

The given equation is

s=4c       ...(ii)

where,

s = number of cups of seltzer.

c = cups of cranberry juice.

On comparing (i) and (ii), we get

Independent variable: x=c

Dependent variable: y=s

Constant of proportionality: k=4

Therefore, the constant of proportionality is 4.
