If f(x) = -5x – 4 and g(x) = -3x - 2, find (f+ g)(x). A. (f+ g)(x) = -5^x– 3x - 6
B. (f+ g)(x) = -8x-6
C. (f+g)(x) = 5^x + 3x + 6
D. (f+ g)(x) = -5^x – 7x-2

positive

step-by-step explanation:

the quadrant is facing upwards

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

i think it would be c
