What is the inverse of the function f(x) = 2x – 10?
posledela

Hey there!!

f(x) is basically ' y '

In order to inverse a equation, we will need to switch the values of x and y

The equation :

y = 2x - 10

Now switching the positions :

x = 2y - 10

x + 10 = 2y

y = \frac{x+10}{2}

y = \frac{x}{2} + 5

This is the inverse.

Hope my answer helps!

  • c+a= 250 ⇒ a= 250- c

  • 1.5c +4(250-c)= 750 ⇒
  • 1.5c- 4c+1000=750 ⇒
  • 2.5 c= 250 ⇒
  • c= 100
  • a= 250-100 ⇒
  • a= 150

Children 100, adults 150
