7. roger has the graph of f(x) = -4x2 but needs to sketch the graph of g(x) - (x+3)2 + . describe how roger can use the graph of f(x) to sketch the graph of g(x). (7 points)

Elena and her husband marc both drive to work. elena's car has a current mileage (total distance driven) of 15,000 and she drives 23,000 miles more each year. marc's car has a current mileage of 46,000 and he drives 9,000 miles more each year. will the mileages for the two cars ever be equal? explain.

Plot the points (0,6), (3,15.8), and (9.5,0) using the graphing tool, and find the function

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?
