Answer:
Point C occurs on the line x = 1
Point D occurs on the line y = -2
The intersection of both lines occurs at the point E = (1,-2)
The difference between the x coordinates of points D and E is 1 + 1/4 units
The difference between the y coordinates of points C and E is 1 unit
Let point F be the point that is 1/4 the distance from point C to point D
To find the x-coordinate F subtract the difference between the x coordinate of points C and E from the x-coordinate of C:
1 - (1 + 1/4) = -1/4
To find the y-coordinate of F subtract the difference between the y-coordinates of D and E from the y-coordinate of C
2 - 1 = 1
The coordinates of point F are (-1/4, 1)
Therefore, the y value of the point that is 1/4th the
Answer: Let x represent the cost of one of Tanya's items.
Then the cost of one of Tony's items =x - 2.25. But we have:
3x =4(x - 2.25)
3x =4x - 9 subtract 3x from both sides
0 =x - 9 add 9 to both sides
x=$9 The cost of one of Tanya's items
27 Total cost of Tanya's 3 items
2.25 =$6.75 cost of one of Tony's items.
27 Total cost of Tony's 4 items.
3 x 6.75 =$27. This shows that both Tony and Tanya spent the same amount of money.
