Use the following functions: yf(x) = 3x - 7 g(x) = 2x - 4
1. Find (f + g)(x).
2. Find (f - g)(x).

(f + g) (x) = 5x - 11

(f - g) (x) = x + 3

Step-by-step explanation:

f(x) = 3x - 7

g(x) = 2x - 4

to find ; (f + g) (x) and (f - g) (x)

now,

(f + g ) (x) =  f (x) + g(x)

                =  (3x - 7) +( 2x - 4 )

                =  3x - 7 + 2x - 4

                 =  5x - 11

again ,

(f - g ) (x) = f(x) - g(x)

                = (3x - 7) - (2x - 4)

                = 3x - 7 - 2x + 4

                =  x + 3

i'm sorry i don't know

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
