Answer:
Step-by-step explanation:
98=49x2
7x7=49
98=
The first given equation is:
4y + 1 = x .......> equation I
The second given equation is:
2x = 5y .......> equation II
Substitute with equation I in equation II to get the value of y as follows:
2x = 5y
2(4y+1) = 5y
8y + 2 = 5y
8y - 5y = -2
3y = -2
y = -2/3
Substitute with the value of y in equation I to get the value of x as follows:
x = 4y + 1
x = 4(-2/3) + 1
x = -5/3
Based on the above calculations:
x = -5/3
y = -2/3

Answer:
See the table attached for a list of the dilated coordinates.
Step-by-step explanation:
Each image point will be the midpoint* of the segment joining the center of dilation with the pre-image point. Since there are so many, it is convenient to use a spreadsheet to calculate them.
- A'(-1.5, 5)
- B'(1.5, 1.5)
- C'(-1.5, 4.5)
- D'(1.5, 6)
- E'(-1.5, 2.5)
- F'(2.5, 5)
_____
* The points are the midpoint because the scale factor is 1/2. That is, the distance from the center of dilation (COD) in the image is 1/2 the distance from the COD to a point in the pre-image. Any midpoint is the average of the two endpoints.
Here, that means the image point is half the sum of the coordinates of the pre-image point and (-4, 2). That is what the spreadsheet calculates.
