What is the inverse of the function f(x) = 2x + 1? h(x) = one-halfx – one-half h(x) = one-halfx + one-half h(x) = one-halfx – 2 h(x) = one-halfx + 2

Step-by-step explanation:

To find the inverse we just switch f(x) and x so we get :

x = 2f(x) + 1

2f(x) = x - 1

h(x) = 1/2x - 1/2

Hope this helps!

the answer is d

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).
