The expression 100 + 20m100+20m100, plus, 20, m gives the volume of water in Marcel’s pool (in liters) after Marcel spends mmm m

Nady [450]

All you have to do is you only need to evaluate the given equation which is:100 + 20m where m would be the number of minutes = 5 1/4 minutes
100 + 20 (5 1/4)
= 100 + 105
= 205 cubic liters is the volume of water in Marcel’s pool after he fills it.

Answer: D) reflection across y = -x

Explanation:

When we reflect over y = x, we basically swap x and y. So for instance, the point (3,1) becomes (1,3).

When reflecting over y = -x, we will do the same thing but we'll make each coordinate swap in sign from positive to negative (or vice versa). The rule for reflecting over y = -x is $(x,y) \to (-y,-x)$
