Hint: There are 4 true statements. A wrong choice cancels the point of a correct choice. Choose wisely.

Now as a function. If you figured out #13 correctly, this is just putting that infor into function notation. Or use these choices here to help you think about #13 better.

r(w)=75

r(w)=75-w

r(w)=75-4.5w

Points on this graph should match the table. I should see at least 3 points and a line through from x axis to y axis.

Solve r(w)=30. You could solve using algebra or your graph that you made.

Extra Credit!! You can either solve the equation
2x + 3 = 6x - 9 OR tell me Ms. Cowan's favorite color.

R(.5)=14

There were 14 mm of water in the gauge after half an hour of rain.

There was a half mm of water in the rain gauge after it rained for 14 hours

Raining for half an hour equaled the rain of raining for 14 minutes.

Half a drop of rain makes 14 daisies

Using function notation...

R(t)=6

R(6)=t

R(6)=37

R(37)=6

Using function notation...Make sure to reread the definition of the variables. That will help eliminate some answers.

R(1.5)=90

R(1.5)=R(2)

R(90)=2

R(2)=90

After how many years will they be the same?

Select all years that make the inequality true.
