Answer: <em>(-2, -1) and (3, 14).</em>
Step-by-step explanation:
![\left \Bigg \{ { \bigg{y=x^{2} +2x-1} \atop \bigg {y-3x=5}} \right. ; \left \Bigg \{ { \bigg{y=x^{2} +2x-1} \atop \bigg {y=5+3x}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5CBigg%20%5C%7B%20%7B%20%5Cbigg%7By%3Dx%5E%7B2%7D%20%2B2x-1%7D%20%5Catop%20%20%5Cbigg%20%7By-3x%3D5%7D%7D%20%5Cright.%20%3B%20%5Cleft%20%5CBigg%20%5C%7B%20%7B%20%5Cbigg%7By%3Dx%5E%7B2%7D%20%2B2x-1%7D%20%5Catop%20%20%5Cbigg%20%7By%3D5%2B3x%7D%7D%20%5Cright.)
<em>x² + 2x - 1 = 5 + 3x</em>
<em>x² + 2x - 1 - 5 - 3x = 0</em>
<em>x² - x - 6 = 0</em>
<em />
<em />
<em>y = 5 + 3x</em>
<em>y₁ = 5 + 3 * (-2) = -1</em>
<em>y₂ = 5 + 3 * 3 = 14</em>
<em>The pair of points representing the solution set of this system of equations is (-2, -1) and (3, 14).</em>
1 gal + 2 qt + 3 pts
1 gal + 3 qt + 7 pts
1 gal + 3 qt + 3 pts
----------------------------add
3 gal + 8 qt + 13 pts
1 gal = 4 qts
1 gal = 8 pts
1 pt = 1/2 qt
13 pts = 6.5 qts
now we have 3 gal + (8 + 6.5) = 3 gal + 14.5 qts
12 qts = 3 gal
now we have : 6 gal + 2.5 qts or 6 gal + 2 qts + 1 pt <=== answer
Answer:
Perimeter, ![P=\dfrac{2}{5}(5x+14)](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7B2%7D%7B5%7D%285x%2B14%29)
Step-by-step explanation:
We have, a hand woven rectangular rug measures x ft long and
wide. For a rectangular shaped object, perimeter is equal to the sum of all sides. If l is length and b is width, then
Perimeter, ![P=2(l+b)](https://tex.z-dn.net/?f=P%3D2%28l%2Bb%29)
We have, l = x ft and b = ![2\dfrac{4}{5}\ ft=\dfrac{14}{5}\ ft](https://tex.z-dn.net/?f=2%5Cdfrac%7B4%7D%7B5%7D%5C%20ft%3D%5Cdfrac%7B14%7D%7B5%7D%5C%20ft)
So,
![P=2(x+\dfrac{14}{5})](https://tex.z-dn.net/?f=P%3D2%28x%2B%5Cdfrac%7B14%7D%7B5%7D%29)
or
![P=\dfrac{2}{5}(5x+14)](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7B2%7D%7B5%7D%285x%2B14%29)
