49.5 mph
just multiply the miles by 2 because it is only half an hour
13 ESSA É A RESPOSTA CORRETA DA SUA PERGUNTA.
Answer:v=4
v=16
v=4/3
v=64/3
Step-by-step explanation: i just did the assignment.
the function is increasing from x = 0 to x = 1
when x = 0, y = 2
when x = 1, y = 8
this shows an increase of +6, so we know this statement is true
we can see the rest are false simply because they state a decrease when there is an increase. this question is only confusing because we ask you about the increase and decrease in the function, when really its the same thing as asking about an increase or decrease in the y variable.
in other words, all youre looking for is the variation of the value of the y variable that is attached to the specific x variables.
hope this helps!!
