Answer:
B. neither perpendicular nor parallel
Step-by-step explanation:
If the lines were perpendicular, the coefficients would be swapped and one negated. (You would have 8x -y = c, or 9x +2y = c in the system.)
If the lines were parallel, the coefficients in the two equations would only differ by a common factor. (Both equations would reduce to 2x -9y = c, or x +8y = c.)
The lines are not the same line (coefficients are different).
So, the only reasonable description is ...
neither perpendicular nor parallel
Without further information, you can't deduce the length of one side of a triangle knowing the other two.
You can only use the inequalities that tell you that the sum of two sides is greater than the remaining one to get
which is true for all positive x values
So, knowing only the length of two of the sides, we can only say that the third side is between 3 and 35 inches long.

To solve this division would be the best way to go. First, set the 2 and 1/2 cups as 5/2. Then go to the lowest common denominator of 4 making 5/2 into 10/4. 3/4 can go into 10/4 3 times meaning that Roger can make 3 loaves of bread.
