Please note translations are just movements on a axis, they are not changing the length of a segment at all. In fact, only dilations change the figure. The length of E'F' is going to be the same as the length of EF.

Answer:
The answer to your question is y = 4 - 1.5x
Step-by-step explanation:
Data
River's speed = 2 mi/h
David's speed = 6 mi/h
Rate of change = 1.5 mi/h
From the data given, we can conclude that the rate of the boat will be the difference between David's speed and the speed of the boat = 4mi/h.
The slope must be negative because it decreases.
The only equation that satisfies both conditions is the second option.
(20*30)/2 = 300
300 km is the area of the triangle
Answer:
- small prism: 630 m²
- large prism: 2520 m²
Step-by-step explanation:
The total surface area of the prism is the sum of the base area and the lateral area. The base area is made up of two right triangles, so will be the product of the triangle leg dimensions. The lateral area is made up of three rectangles whose width is that of the prism and whose equivalent length is the perimeter of the triangle base.
For the smaller prism, the area is ...
(20 m)(21 m) +(3 m)(20 m + 21 m + 29 m) = 420 m² +210 m² = 630 m²
The larger prism is similar, with a scale factor of 2, so its area will be 2² = 4 times that of the smaller prism:
4×630 m² = 2520 m²
__
In summary, the total surface area of each prism is ...
- small prism: 630 m²
- large prism: 2520 m²
