Vertex form: y = a(x - h)² + k
h = 2
k = -1
y = 0
x = 5
0 = a(5 - 2)² - 1
0 = 9a - 1
a = 1/9
Answer:
The Svensons' assets increased by $1,800.
Step-by-step explanation:
I just took the quiz!
Given that,
An equation : -9c² +2c +3 = 0
To find,
Find the value of x.
Solution,
We have, -9c² +2c +3 = 0
We can solve it using the formula as follows :

Here, a = -9, b = 2 and c =3
Put the values,

So, the solution are -0.47 and 0.69.
Answer:
-5r + 8r +5
= (-5+8)r+5 (we can calculate number in same variabe)
