Step-by-step explanation:
A direct proportion has a formula that is written this way: y=kx
what does that mean ?
There is an image at the end to make you understand .
a direct proportion is a straight line that must go from the origin . why?
- simply beacuse it equals 0 in 0 . y=k*0=0 . so the coordinates of that point are (0,0) wich is the origin !
- a direct proportion must have a constant slope to make it go straight or it wouldn't be a straight line . i left an image to make it clear
- a diect proprtion must not have a slope of 1 . it can be 1, 2,100000 or 0.5
- its graph must be linear
Answer:
Let x = cube root of 400
Using a calculator x = 7.368 to 3 decimal places
So: 7 < x < 8
It is a scalene triangle.
