Answer:
h=-3
Step-by-step explanation:
Combine like terms ( -2.5h )
1.8=-2.5h-5.7
Add 5.7 to 1.8 ( 7.5 )
Bring down -2.5h
the divide ( 7.5/-2.5 )
h= -3
ertificates 6.00% per annum ---x
AA bond 11.00% per annum ---y
x + 1 y= 160000 ------------------------1
6.00% x + 11.00% y= 15600
Multiply by 100
6 x + 11 y= 1560000.00 --------2
Multiply (1) by -6
we get
-6 x -6 y= -960000.00
Answer:

Step-by-step explanation:
we know that
The equation of a vertical parabola into vertex form is equal to

where (h,k) is the vertex of the parabola
The axis of symmetry is equal to

In this problem the parabola open upward
so
the coefficient a is positive
The coordinates of the vertex will be
(the y-coordinate is negative)
so
the equation will be of the form
