Answer: 1st Graph.
The first graph represents the problem because 1/2x is the x intercept, so 1/2 intersects the x-axis.
Basically, the x intercepts are
They're aren't any Y intercepts because it will never intersect the y-axis, so it must be parallel.
Hence, the 1st Graph represents your equation.
Its 5.9 cus you have the perimeter to 68 and the with 8.9 so its 5.9
The answer is n=28;
1. Subtract 14 from both sides (-n/2 = -14)
2. Multiply by 2 on both sides to get rid of the fraction (-n = -28)
3. Divide by -1 to get n by itself (n = 28)
You could also eliminate step three by multiplying by -2 instead of just 2.
Hope this helps!
the answer is (1,-2) hopefully is the correct answer
