Answer:
1st option
Step-by-step explanation:
let y = f(x) and rearrange making x the subject
y = 2x + 1 ( subtract 1 from both sides )
y - 1 = 2x ( divide both sides by 2 )
= x
Change y back into terms of x with x being the inverse h(x)
h(x) = 
= 
x -
Answer:
x = 13
Step-by-step explanation:
The sum of the exterior angles of a 4 sided polygon is 360
139+ 6x+9x+2x = 360
Combine like terms
139+17x=360
Subtract 139 from each side
17x = 360-139
17x = 221
Divide each side by 17
17x/17 = 221/17
x = 13
Answer:

Step-by-step explanation:
Answer:
DE = 15
DF = 23
Step-by-step explanation:
E___D___F
EF = DE + DF
38 = (3x +9) + (12x-1)
38 = 15x + 8
15x = 38 - 8
15x = 30
x = 30/15
x = 2
DE = 3x + 9 = 3(2) + 9 = 6 + 9 = 15
DF = 12x - 1 = 12(2) - 1 = 24 - 1 = 23
