4. Given the function y = 1 + 5 of kx-k, find the value of K according to the following conditions The function image passes through the origin The point (0, - 5) is on the function image The function image is parallel to the line y = (1-half K) x-3

4. Given the function y = 1 + 5 of kx-k, find the value of K according to the following conditions The function image passes through the origin The point (0, - 5) is on the function image The function image is parallel to the line y = (1-half K) x-3

Function image passes through the origin (0,0)
Take it into the equation,
0=0-1/k+5
k=0.2
The point (0, - 5) is on the function image
The same is true
The function image is parallel to the line y = (1-half K) x-3
That is y = (1-0.5k) x-3
If two lines are parallel, the slope should be equal
1-0.5k=k
k=2/3

How much is the largest volume of a cuboid like 11dm long, 6dm wide and 2DM high cut into a small cube? How many pieces can it be cut into?

2 × 2 = 4 (cubic decimeter)
11 △ 2 = 5 (block) ····· 1 (decimeter)
6 △ 2 = 3 (block)
2 △ 2 = 1 (block)
1 × 3 × 5 = 15 (pieces)
A: the largest volume of a cube is 4 cubic decimeters, which can be cut into 15 such cubes
