Answer: The distance which reduces to 7.28
Step-by-step explanation:
To find the distance between these two coordinates, find the difference of the y coordinates and x coordinates and square them then add them together to find their square root.
The y coordinates are 1 and -1.
The x coordinates are -5 and 2.
So -1-1 = -2
-5 - 2= - 7 Find their absolute values.
The absolute value of -2 is 2 and the absolute value of -7 is 7.
2^2 + 7^2 = d^2 where d is the distance.
4 +49 = d^2
53= d^2
d=
d= 7.28

Answer:
Initial value for Mrs. White is $600 more than Mrs. Brown.
The rate of change is same for both.
Step-by-step explanation:
Cost of car purchased by Mrs. White = $3,000
Rate at which she pays for the car = $300 per month
Cost of car purchased by Mrs. Brown = $2,400
Rate at which she pays for the car = $300 per month
So,
Initial value for Mrs. White was =$3,000
Initial values for Mrs. Brown was =$2,400
difference in initial values =$600
∴ Initial value for Mrs. White is $600 more than Mrs. Brown.
Rate of change of payment due for Mrs. White = $300 per month
Rate of change for payment due for Mrs. Brown = $300 per month
∴ The rate of change is same for both.
Since Mrs White had a higher initial value than Mrs Brown and both having same rates of change, therefore Mrs. White will take a longer time to pay the due.
