To find the x-intercept, set y = 0 in y = mx + c. This yields 0 = mx + c, which solves to x = −c/m, provided m ≠ 0. Ganita Manjari Class 9 Maths part 2 Chapter 13 Solutions Class ...

The cover lines represent the chapter’s opening equations x + y = 7 and x − y = 1. Solving them simultaneously by addition gives 2x = 8, so x = 4 and y = 3, intersecting at (4, 3). Class ...
Line 2x + y = 6 passes through (0, 6) and (3, 0). Line 2x − y = 2 passes through (0, −2) and (1, 0). Plotted on a graph, both lines intersect at (2, 2). Ganita Manjari Part 2 Class ...
Model the house as a combination of rectangular cuboids for rooms. For an apartment measuring 10 m length, 8 m width and 3 m ceiling height, the approximate interior volume is 10 × 8 × 3 = 240 m³. Cbse Class ...
Consider changing dimensions from (l, w, h) to (l’, w’, h’). One valid example: an initial cuboid of dimensions 1 × 1 × 8 has V = 8 and SA = 34. Rescaling dimensions to 0.25 × 2 × 8 ...
