If fx = 3x over 5 +3 which of the following is the inverse
Alborosie

Answer:

f^(-1)(x) = -3x/(3x-3)

Step-by-step explanation:

1) replace f(x) by y

● y = 3x/(5x+3)

2) exchange x and y

● y = 3x/(5x+3)

● x = 3y / (3y +3)

3) solve for y

● x = 3y / (3y +3)

● x (3y +3) = 3y

● 3xy + 3x = 3y

● 3xy - 3y = -3x

● y (3x - 3) = -3x

● y = -3x /(3x-3)

4) replace y with f^(-1)(x)

● y = -3x/(3x-3)

● f^(-1)(x) = -3x/(3x-3)

PLEASE HELP I really need help with it:/
Luda [366]

Answer:

  • q = 14

Step-by-step explanation:

<u>We know that:</u>

  • 39 + (4q - 5) = 90°

<u>Solution:</u>

  • 34 + 4q = 90°
  • => 4q = 90 - 34
  • => 4q = 56
  • => q = 56/4
  • => q = 14

Hence, the value of q is 14.
