Answer:
"A" would be positive 2/ no, it is not because the opposite of 2 is -2
Step-by-step explanation:
negative and a negative is a positive
Answer:
y = -3(x + 1)² + 9
Step-by-step explanation:
y = a(x - h)² + k, where (h, k) is the vertex
The vertex of the quadratic function is (-1, 9)
The only equation listed that has a vertex at (-1, 9) is:
y = -3(x + 1)² + 9
So, he deposited 17 dollars, ( 4 ) 5 dollar bills, and 6 twenty dollar bills.
5 + 5 + 5 + 5 = 20
20 x 6 = 120
120 + 20 = 140
140 + 17 = 157
He deposited a total of <u>157 dollars.</u>
hope this helps!
Answer:
.12
Step-by-step explanation:
So have the sequence:

To check if the sequence is geometric, we are going to find its common ratio; to do it we are going to use the formula:

where

is the common ratio

is the current term in the sequence

is the previous term in the sequence
In other words we are going to divide the current term by the previous term a few times, and we will to check if that ratio is the same:
For

and

:


For

and

:


For

and

:


As you can see, we have a common ratio!
We can conclude that our sequence is a geometric sequence and its common ratio is
