Step-by-step explanation:
here is the answer. Since the equation was getting a little messy, I decided to use matrices to solve it, but you can still do it the normal way and still yield the same result, though it might be a bit more tedious.
If a 12-ounce can of corn costs 69 cents the rate would be 69 cents for 12 ounces.
Answer:
The vertex is the minimum point on the graph, which is (1,-2)
The answer is a square prisom
When 1-5x>0, 1> 5x, x< 1/5, then |1-5x|=1-5x
6(1-5x)-9=57
6-6*5x-9=57
-30x-3=57
-30x=57+3
-30x=60
x=-60/30
x=-2 is a solution because -2<1/5
