Ski rentals are $100 plus $18 per hour, as shown in the table above. 1. Write an equation that represents this data using function notation. Let x represents the time in hours and f (x) represents the rental cost.

2. What would be f (6)? Show your work.

3. If f (x) = 235, what is x? Show your work.

BE SURE TO LABEL YOUR RESPONSES 1, 2, AND 3.

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?

X+y=-4 x-y=2 use elimination with adding and subtraction
