Answer:
Step-by-step explanation:
Hello!
In order to answer this question, we need to use the distance formula.
The order of these points can be chosen in any way, but they need to be done in the same pair (just like when you find the slope).
For this problem, let's let the J pair be the 
pair and the K pair be the 
pair.
= -3
= 2
= 2
= -2
Now, let's plug these points in.
Thus, the distance between points (-3,2) and (2,-2) is .
That's a dollar n 44 cents Ik that's right

Answer:
-100
Step-by-step explanation:
1/5 of -125 will be -25.
So, if she deposits 1/5 of what she owes, then she will deposit $25.
Her balance will then become -100 because she paid back 25.
Her new balance is -100
Answer:
at least 450 minutes
Step-by-step explanation:
Find an expression for the cost of each plan as a function of the number of minutes. Set the expressions equal to each other, and solve for the number of minutes.
Let x = number of minutes.
First plan:
cost (in dollars) = 0.21x
Second plan:
cost (in dollars) = 0.11x + 44.95
Set the expressions equal:
0.21x = 0.11x + 44.95
Subtract 0.11x from both sides.
0.1x = 44.95
Divide both sides by 0.1
x = 44.95/0.1
x = 449.5
Since you cannot have a fraction of a minute, the answer is 450 minutes.
