Revenue, R = 130x


Profit, P = Revenue – Cost


 P = R – C


P = 130x – 2950 + 6x + 0.1x^2


At P = 0


0 = -2950 + 136x +0.1x^2


X = 21.355, -1381.355

Help<br>i need H - G answered ​
exis [7]

Answer:

See below.

Step-by-step explanation:

H.

f = 3x + 31

c = 12x - 1

3x + 31 + 12x - 1 = 180

15x + 30 = 180

15x = 150

x = 10

same-side interior, supplementary

R.

b = x - 10

g = 4x + 60

x - 10 + 4x + 60 = 180

5x + 50 = 180

5x = 130

x = 26

same-side exterior, supplementary

E.

d = 2x + 13

e = 7x + 5

2x + 13 + 7x + 5 = 180

9x + 18 = 180

9x = 162

x = 18

same-side interior, supplementary

I.

a = 10x - 30

e = 8x + 20

10x - 30 = 8x + 20

2x = 50

x = 25

corresponding, congruent

G.

b = x + 30

h = 5x - 14

5x - 14 = x + 30

4x = 44

x = 11

alternate exterior, congruent
