if a trip takes 40 minutes when you travel 50 mph how many minutes would it take if you travel 40 mph

Step-by-step explanation:

40 minutes × (50 miles)/(60 minutes) = 100/3 miles

100/3 miles × (60 minutes)/(40 miles) = 50 minutes

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
