Determine whether the relation is a function. {(−3,−6),(−2,−4),(−1,−2),(0,0),(1,2),(2,4),(3,6)}
Gennadij [26K]

Answer:

The relation is a function.

Step-by-step explanation:

In order for the relation to be a function, every input must only have one output. Basically, you can't have 2 outputs for 1 input but you can have 2 inputs for 1 output. Looking at all of the points in the relation, we see that no input has multiple outputs, so the answer is yes, the relation is a function.

Answer:

L = 7 W= 12

Step-by-step explanation:

Ok so we already know that a rectangle is not even so the numbers will have to be 2 diff numbers.

The length is 5 feet less then width

w*l=  84

1* 84         2* 41        3*28    4*21    6*14    7*12

84-1           41-2        28-3     21-4     14-6   12-7

83              39           25          19        8         5

So,

your equation would be l*w = 7*12
