120+40x=180+20x solve for x (show your work please)

x=3

Step-by-step explanation:

40x + 120 = 20x + 180

(40x - 20) + 120 = (20x- 20) + 180

= 20x + 120 = 180

20x + (120-120) = 180 - 120

20x = 60

divide 20 to both sides of 20 and 60 so you will get x=3

y=mx+b is the final answer!   : )

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
