Step-by-step explanation:
Cross multiply and get:
L = 5w
L = 5w/
W = L/5
Which of the following relations is a function? A. (0, 4), (-2, 6), (0, 3), (-7, 2) B. (8, 1), (-2, 4), (0, 1), (8, 2) C. (0, 4)
fomenos
Answer: C
Step-by-step explanation:
C is a function because each of the inputs are distinct, meaning they only have one output each.
The other choices are not functions because at least one of the inputs corresponds to 2 or more outputs.
Answer:
Step-by-step explanation:
Let 
be the greater number and 
be the smaller number. We know that their difference is 15, so we have
Then, we have the following information: if we add twice the greater (2x) and 8 (2x+8), the result is 3 times the lesser (3y) minus four (3y-4). So, we have
So, we have the follwing system:
From the first equation, we can derive 
, and substitute this expression in the second equation to get
Substitute this value for y in the first equation to get
