Answer:
15 minutes
Step-by-step explanation:
The speed of the first machine is 1/10 job/minute.
The speed of the older machine is x.
Their combined speed is:
x + 1/10 = 1/6
Solving for x:
x = 1/6 − 1/10
x = 5/30 − 3/30
x = 2/30
x = 1/15
The speed of the older machine is 1/15 job/minute, so it takes 15 minutes for the older machine to do the job alone.
You are investing $2,000 fro 3 months and the APR is 4% so you will get one quarter of the APR for a year. For the year 4% interest is $2,00 x .04 or $80 for the year. # months is 1/4 of a year so divide $80 by 4 to get the interest fro 3 months which is 20 so the answer is B.

C (-2,2)
D (4,-2)
all ordered pairs are (x,y). x is the horizontal line and y is the vertical line. you count the number of units (or blocks) you have to go to get to the point for both the x-value and the y-value
