Johan is comparing energy consumption for two different brands of refrigerators. The energy consumed "e", in watts, is proportional to the time "t", in hours, that the refrigerator is operating. The equation e=160t models the relationship for brand R. Another refrigerator, brand S, consumes energy at a constant rate of 435 watts in 3 hours. Which brand consumes less energy? Explain.

i can't solve unless i know what the line is

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
