Consider 'a' be the closed region bounded by the following lines in the xy-plane : x 0, x 1, y 0 and the curve which the family of lines y t(2x - t) (where t e r) touches. let 'b' denotes the triangular region bounded by the line y t(2x t) on the region a. 7. area of the region 'a' is equal to - 4 if locus of centroid of b' is a part of parabola with vertex ? ) then (2? + ? ) is equal to 2 (a) i (b) 3 (c) 2

The system of equations graphed below has how many solutions? y = 2x + 2
