Th correct option is A. light colour

Explanation:

An independent variable is described as a variable which doesn't get affected by another variable. In a scientific experiment, an independent variable is a controlled variable whose effects are checked on a dependent variable. Hence, Light colour is independent in the above experiment being performed by Tasha.

A dependent variable changes with a change in any other variable. Hence, light intensity, amount of light and temperature of light are the dependent variables.

the match duh

explanation:

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
