Answer:
(-infinity, 4]
Step-by-step explanation:
The range is the possible y values
The smallest that (x+3)^2 can be is zero
f(x) = 4 − 2(x + 3)^2
f(x) = 4 -2(0) = 4
This is the maximum value
As the square term gets bigger we are subtracting a larger amount and it will get more negative
Let x = infinity, x+3 = infinity and infinity ^2 = infinity and 2* infinity = infinity
f(x) = 4 - infinity
= -infinity
The range is -infinity to 4
18% = 18/100 = 0,18
22000/0,18 = 22000/(18/100) = (22000 . 100)/18 = 1100000/9 = 122222,2222...
So $22,000 divided by 18% is equal to $122.222,22
Answer:
6 $1 bills, 5 $5 bills
Step-by-step explanation:
Say the student has x $1 bills.
Then they have 11 - x $5 bills.
31 = 1 * x + (11 - x) * 5 = 55 - 4x
4x = 55 - 31 = 24
x = 6
So, they have 6 $1 bills and 11 - 6 = 5 $5 bills
This is the definition of a rational number.
