Answer:
y = 1/2 x -14.5
Step-by-step explanation:
2x-4y=58
solve for y
subtract 2x from each side
2x-2x-4y = -2x+58
-4y = -2x+58
divide by -4 on both sides
-4y/-4 = -2x/-4 +58/-4
y = 1/2 x -14.5
Answer: Complementary
x=58

Answer:
I think it's D cause it says less than 3 and all possible ways, so that's the only one that makes sense to me.
Lets say the width is W and the length is L,
So its W * L = 196
but we also know W*4 = L
which means we can substitute L for W * 4 so our equation will be
W*W*4 = 196
W*W = 49
W= 7
Y = kx
Y is the total cost
The number of dvds is x
The cost of each one ($12) is k
y = $12x
Or instead of Y you can but T for total cost
t = $12x
