Step-by-step explanation:
TO show that this system has no solution, use the y value in the second equation and put it in for y in the first. Then solve.
x + 2y = -4
x + 2(-1/2x - 4) = -4
x - x - 8 = -4
-8 = -4
Because this is an incorrect statement, we can tell there is no solution.
Answer:
each pet bird got 1/8 of the bag of birdseed
Step-by-step explanation:
the easiest way to do this is to divide the bag into eighths. if you divide the bag into eighths, 4/8 of the bag, being half, goes into the bird feeder. the other 4/8 of the bag is divided among Mr. Wilson's four pet birds, leaving each bird to get 1/4 of the bag when split evenly.
hope this helps
