Hiiiii ^-^ I can help you XD
Congruent
The same shape and size.
Two shapes are congruent when you can Turn, Flip and/or Slide one so it fits exactly on the other.
In this example the shapes are congruent (you only need to flip one over and move it a little).
Angles are congruent when they are the same size (in degrees or radians).
Sides are congruent when they are the same length.
Answer:
Constant of variation: 1/4
Slope of the line: 1/4
Step-by-step explanation:
The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.
The slope formula states that m = (y2 -- y1) / (x2 -- x1). The slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".
Answer:
2/3 or 67%
Step-by-step explanation:
Please kindly check the attached files for details.
The scale factor is 4 (10/2.5).
Each side has increased by a factor of 4. Think of it logically, if the original rectangle had sides of 1,1,1/4,1/4, the perimeter would add to 2.5. In order to get the sides to add up to 10, each of the sides would need to be multiplied by 4. Then our sides would measure 4,4,1,1 with a perimeter of 10.
