How are the graphs of these ellipses similar and how are they different?
x2100+y2225=1 (x−1)2100+(y+7)2252=1

The explanation how are the graphs of the ellipses x2100+y2225=1 and (x−1)2100+(y+7)2225=1 same and different.
Answer to Problem 1RE
Solution:
Each equation represents an ellipse with a vertical major axis of length 30 units and horizontal minor axis of length 20 units. However, the first equation represents an ellipse centered at (0,0), whereas the second equation represents an ellipse centered at (1, − 7).
Explanation of Solution
Given Information:
The equations of ellipse are x2100+y2225=1 and (x−1)2100+(y+7)2225=1.
Use the formula,
If in the ellipse, the major axis is y-axis, the equation of the ellipse is given by:
(x−h)2b2+(y−k)2a2=1.
Where; the center is (h,k), the length of major axis is 2a and the length of minor axis is 2b.
Consider the provided ellipses:
x2100+y2225=1 and (x−1)2100+(y+7)2225=1
The First Ellipse x2100+y2225=1 in standard form can be written as:
(x−0)2(10)2+(y−0)2(15)2=1
So, the ellipse has its center at (0,0).
Length of the major axis is 2(15)=30 units and the length of minor axis is 2(10)=20 units.
The Second Ellipse:
(x−1)2100+(y+7)2225=1
The ellipse has its center at (1,−7)
Length of the major axis is 2(15)=30 units and the length of minor axis is 2(10)=20 units.
The graphs of the equations are sketched as:
Each equation represents an ellipse with a vertical major axis of length 30 units and horizontal minor axis of length 20 units. However, the first equation represents an ellipse centered at (0,0), whereas the second equation represents an ellipse centered at (1, − 7).
