Answer:
f(x) = y
Step-by-step explanation:
f(x) always equals y, so the equation would be y = 7. therefore, I am pretty sure that x = y, but you may want to wait to ask your teacher. If there is more detail, message me!
Answer:
3rd graph from the top.
Step-by-step explanation:
It can't be the top one because the kids shoulder doesn't start at the ground.
It can't be the second or fourth because it shows him not waiting in line.
Therefore it must be the 3rd!
Answer:
1. a =3(2a) +5 and a= 6a+5
2. 47=3(2times 7) +5 and 47 =6 time 7 plus 5
Step-by-step explanation:
Answer:
C.) x and y are almost perfectly correlated, and y decreases as x is increased.
Step-by-step explanation:
The correlation r is a number between -1 and 1 and it shows the relation between variables x and y. If the number is closed to 0, there isn't a relation between x and y, however if the number is closed to -1 or 1 we can said that they are almost perfectly correlated.
Finally, if the number is positive, it means that y increases as x is increased. On the other side, if the number is negative, y decreases as x is increased.
In this case, r is -0.98, a number that is closed to -1 and negative, it means that x and y are almost perfectly correlated and y decreases as x is increased.
