Answer:
As we strolled along the aged cobblestone walkway that meandered through the rose garden, we gazed at the array of fragrant, colorful blossoms.
Step-by-step explanation:
Mwah there lol <3
Hope it helps
Suppose he invest x dollars in one account, y in the other
x+y=12,500
0.042x+0.062y=669.50
multiple the first equation by 0.042: 0.042x+0.042y=525
subtract this new equation from equation 2: 0.02y=144.50
y=7225
x=12500-7225=5275
It’s organized and you can see it more visually , gives you a way to double check and write down the data properly.
Answer: The equation of an ellipse:

√
a

Use the vertices to write 3 equations:
k
=

[1]
h
−
a
=

[2]
h
+
a
=

[3]
Use equations [2] and [3] to solve for h and a:

h
=

h
=
2
a
=
8
Use the focus to write another equation:
8
=
h
+
√
a
