La otra tarde vi en un parking 39 vehículos, entre coches y motos, a los que les conté un total de 126 ruedas. ¿Cuántos vehículos de cada clase había en el parking?

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)

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.
