Answer:
A is a function; B, C and D are not.
Step-by-step explanation:
In other words: Identify the sole function among these relationships.
A function maps any input onto exactly one output.
If a relationship maps any input onto more than one output, it is not a function.
Thus, we eliminate B, C and D. In B, for example, we have the inputs {1, 2, 3}, where the '1' has two y-values associated with it.
On the other hand, A has the domain {-1, 0, 1, 2}, and all four inputs have exactly one associated output.
Answer: d and e
Step-by-step explanation:
a) 4 - 9 = 5 FALSE
b) 20 = 14 + 9 FALSE
c) 15 = 9 - 6 FALSE
d) 9 divided by 3 = 3 TRUE
e) 36 = 4 x 9 TRUE
Her cousin lives 184 miles away
Explanation: In this problem you need to solve for the distance, and you are given speed and time. With this information, we need to use the speed formula which is s=d/t where s=speed, d=distance, and t=time
Next all you have to do is plug in your values, which should look like this-
40=d/4.6
Now that you have your equation, you must solve for d to get your distance by isolating d to one side of the equation. You do this, by multiplying 4.6 on each side of the equation.
This is what the math should look like-
(4.6)40=d/4.6(4.6)
184=d
d= 184 miles
I hope this helped!
