Answer:
C. The equation x = 50y represents this situation.
Step-by-step explanation:
Let's examine each statement given and determine if it is correct or not correct based in the information given to in the graph.
Statement A: "The point (2, 100) means that there are 100 pounds of wild rice in 2 bags."
✅This is CORRECT because from the graph, on the x-axis (number of bags), when x = 2, y on the y-axis (pounds of wild rice) is 100.
Statement B: "The data represents a proportional relationship".
✅This is CORRECT because a graph that shows a proportional relationship between x and y, has a line that cuts through the point of origin (0, 0).
Statement C: "The equation x = 50y represents this situation".
❌This is NOT CORRECT. The equation does not represent a proportional relationship between x and y. The correct equation should be y = 50x. Where 50 is the constant of proportionality. That is y/x.
Statement D: "The constant of proportionality is 50."
✅this is CORRECT because constant of proportionality = y/x = 100/2 = 50.
Answer:
The red segment is from 1/4 to 3/4.
Step-by-step explanation :
Answer:
The red segment is from 1/4 to 3/4.
3/4 - 1/4 = 2/4
2/4 = 1/2
1/2
This answer can also be found by seeing there are four equal boxes making up the one larger box, since two out of the four boxes are filled then the fraction would be 2/4, which simplifies to 1/2
The reflection of any point across the x axis is the symmetric of this point, having x axis as axe of symmetry
Let :
A(1,3) its symmetric vs. x axis is A'(1,-3)
B(-1,5) its symmetric vs. x axis is B'(-1,-5)
C(-3,-3) its symmetric vs. x axis is C'(-3,3)
D(-4,-4) its symmetric vs. x axis is D'(-4,4)
Symmetry vs. the x axis keeps abscises the same & change just the sign of y value
