Answer:
c. y = (x +2)² -5
Step-by-step explanation:
If you replace the squared term with zero, you are choosing the minimum of the remaining values. (A squared term cannot have a negative value.)
a) 3
b) 4
c) -5 . . . . the graph with the least possible y-value
d) 0
Let's say the point is C, so C partitions AB into two pieces, where AC is at a ratio of 3 and CB is at a ratio of 7, thus 3:7,

Answer:
-2
Step-by-step explanation:
Start with the vertex form of the equation of a parabola: y - k = a(x - h)^2
Here h = -2, k = -3, x = -1, y = -5. Find a:
-5 - [-3] = a(-1 - [-2])^2, or
-5 + 3 = a(1)^2, or
-2 = a
The unknown coefficient is -2.
<u>Answer:</u>
Annual Income of A=
and
Annual Income of B=
<u>Step-by-step explanation:</u>
<u>Given Data:</u>
Ratio of annual income of A and B=4:3
Ratio of expenditures of A and B=3:2
Saving of A and B=1000
<u>Required:</u> Annual Income of A and B=?
<u>Solution:</u>
If ratio of income of A and B is 4:3
then let Income of A=
and Income of B=
If ratio of expenditure of A and B is 3:2
then let expenditure of A=
and expenditure of B=
Therefore,
...........
and
..........
subtracting Eq(1) and Eq(2), we get


putting
in Eq(1), we get value of
as

because x and y are equal in Eq (3)
Now, Annual Income of A=
and Annual Income of B=
