In figure 3, OAC is a triangle and ADBC IS a straight line with OA->. =a and OB->= b. The point D on AB is such that AD: DB = 3:1. A) express in terms a and v simplyfying each answer where possible (I) Ab ->. Ii)OD->

The triangles are similar. what is the value of x? show your work.

Isabel graphed the following system of equations. 2x – y = 6 y = -3x + 4 she came up with the solution (2,-2). what were the 3 steps she did to get that solution? (make sure they are in the correct order)
