The given ratio is:
To find the unit cost per ounce, we can use proportions as follows:
Now, solve for x:
The cost per ounce (unit cost) is then $0.12/oz
Please help me on this question and explain.

Okay. For this question, basically all you have to do is plug in the domain values for x and solve from there. I'll help you with the first 3.
So 3/2 is equivalent to 1.5. A negative times a positive is a negative. -8 * 1.5 is -12. -12 + 4 is -8. That makes the ordered pair (-8, -8). To -4, -4 * 1.5 is -6. -6 + 4 is -2. That makes the ordered pair (-4, -2). Now to -2, -2 * 1.5 is -3. -3 + 4 is 1. That makes (-2, 1). If you solve for the other 3 values correctly, you other ordered pairs are (0, 4), (2, 7), and (4, 10). When graphed, the points should be plotted as shown in the attatchment.

Answer:
Length = 17 feet, Width = 5 feet
Step-by-step explanation:
Given:
The area of a rectangular wall of a barn is 85 square feet.
Its length is 12 feet longer than the width.
Question asked:
Find the length and width of the wall of the barn.
Solution:
Let width of a rectangular wall of a barn =
<u>As length is 12 feet longer than the width.</u>
Length of a rectangular wall of a barn =
As we know:
Subtracting both sides by 85
As width can never be in negative, hence width of a rectangular wall of a barn = = 5 feet
Length of a rectangular wall of a barn =
Therefore, length and width of the wall of the barn is 17 feet and 5 feet respectively.
