Two Trains Train A and Train B, weigh a total of 285 tons. Train A is heavier than Train B. The Difference of their weights is 221 tons. What is the weight of each​ train?

312-170=142

142÷2=71

170+71=241

241+71=312

train A weighs 241 tons

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

a reflection across the x axis and a 90 degree rotation left and right.
