<span>(x, y)→(x − 8, y − 7) is the correct translation. Take point D for example. The coordinate of D is (2, 5). The coordinate of D' (after translation) is (-6, -2). Since 2-8=-6, 5-7=-2, only the first choice is correct. You can also try other points and see why only this is the right translation.</span>
Answer:3x+5y=210
Step-by-step explanation:
We dont know how much of each fish they bought so we would add an x and a y. A answer you can put are:
35 pounds of tilapia and 21 pounds of salmon.
Answer:
i think that the answer would be but im not 100% sure

Answer:
Rain is correct, calculates correctly, 238.5 square inches
Step-by-step explanation:
The given triangular pyramid is shown with the dimensions.
The surface area of the triangular pyramid is given by :
![$A=\frac{1}{2}\left(a \times b\right) + 3\left(\frac{1}{2}\times b\times s\right)$](https://tex.z-dn.net/?f=%24A%3D%5Cfrac%7B1%7D%7B2%7D%5Cleft%28a%20%5Ctimes%20b%5Cright%29%20%2B%203%5Cleft%28%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20b%5Ctimes%20s%5Cright%29%24)
![$A=\frac{1}{2}\left(10 \times 8.7\right) + 3\left(\frac{1}{2}\times 10\times 13\right)$](https://tex.z-dn.net/?f=%24A%3D%5Cfrac%7B1%7D%7B2%7D%5Cleft%2810%20%5Ctimes%208.7%5Cright%29%20%2B%203%5Cleft%28%5Cfrac%7B1%7D%7B2%7D%5Ctimes%2010%5Ctimes%2013%5Cright%29%24)
![$A=43.5+(3\times 65)$](https://tex.z-dn.net/?f=%24A%3D43.5%2B%283%5Ctimes%2065%29%24)
![$A=43.5+195$](https://tex.z-dn.net/?f=%24A%3D43.5%2B195%24)
![$A=238.5 \ \text{inche}^2$](https://tex.z-dn.net/?f=%24A%3D238.5%20%5C%20%5Ctext%7Binche%7D%5E2%24)
Therefore, the surface area of the triangular pyramid is = 238.5 square inches.
