write a equation for the table below representing the relationship between the number of hours and earring dollars

On a piece of paper graph f(x)=5•(0.4)^x

He that is measured at 220° is a reflex angle. the opposite angle is obtuse. find the measure of obtuse .

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
