Answer:
To find all coordinates, we just need to observe the graph.
The coordinates of point C are (2c,d). From the graph, we notice that the x-coordinate of C is the same x-coordinate of V, because they are in the same vertical lines.
The coordinates of point D are (c,0). The problem states that D is a mid point, so basically its coordinate is half of point's V, which is c.
The slope of both AB and DC is d/c. The slope is the fraction between y-coordinate and x-coordinate. If you we calculate the slope of DC, we would have d as vertical coordinate and c as horizontal coordinate.
The slop of both AD and BC is -b/c-a. The slope between the points A(a,b) and D(c,0) is
William is 17 and Charmine is 14
let Charmine's age be x then William is x + 3, then
3x + 2(x + 3 ) = 76
3x + 2x + 6 = 76
5x + 6 = 76 ( subtract 6 from both sides )
5x = 70 ( divide both sides by 5 )
x = 14
Charmine is 14 and William is 14 + 3 = 17
Answer:
$21.25
Step-by-step explanation:
2 bags =8.50
1 bag =4.25
8.50+8.50+4.25=21.25
