Answer: y = 1200m + 57,600
Step-by-step explanation: To be a line, let's say that x is the numbers of years on the job and y the salary.
So, we have (2,60000) and (7,66000)
y = mx + b
66000 = 7m + b
60000 = 2m + b (-)
________________________
6000 = 5m
m = 6000/5 = 1200
60000 = 2m + b
60000 = 2.1200 + b
60000 = 2400 + b
b = 60000 - 2400
b = 57600
y = mx + b
y = 1200m + 57,600
Answer:
7%
Step-by-step explanation:
Step one:
given data
The original cost of Sam’s investment is $10,000
Sam calculated his real return to be $10,700
Required:
the interest made from the investment is
10700-10000= $700
Step two:
The ROI is a percentage that tells us the interest made
interest/investment*100
=700/10000*100
=0.07*100
= 7%
The ROI is 7%

Answer:
The axis of symmetry is x = 6
Step-by-step explanation:
To find this, first find the two x-intercept values and then take the average. This will always be the line of symmetry.
x + 9 = 0
x = -9
x - 21 = 0
x = 21
Now take the average of these two numbers.
(-9 + 21)/2
12/2
