Teniendo en cuenta la propiedad fundamental de las proporciones, comprueba si las siguientes son o no proporciones a) 5/7 = 15/21 b) 20/7 = 5/3 c) 16/8 = 4/2

it could be 1,3 and more others to create a cylinder.

step-by-step explanation:

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
