Probe every pair:
pair x y 7x - 5y
A. (-6,-14) -6 -14 7(-6) - 5(-14) = -42 + 70 = 28 => it is a solution
B. (7,9) 7 9 7(7) - 5(9) = 49 - 45 = 4 => not a solution
C. (4,10) 4 10 7(4) - 5(10) = 28 - 50 = - 22 => not a solution
C. (-1,-7) -1 -7 7(-1) - 5(-7) = -7 + 35 = 28 => it is a solution
Answer: option A. (-6,-14) and option D. (-1,-7)
Use the coordinates and plot them. On the graph, count the weight and height.
Answer:
The yearly value of the card 25 years later is $16.93.
Step-by-step explanation:
You can use the following formula to find the future value:
FV=PV(1+r)^n
FV= future value
PV= present value= 5
r=rate= 0.05
n=number of periods of time= 25
Now, you can replace the values in the formula:
FV=5(1+0.05)^25
FV=5(1.05)^25
FV=16.93
According to this, the answer is that the yearly value of the card 25 years later is $16.93.
The probability that all five end up in alphabetical order is; 1/120.
<h3>What is the probability that the rack ends up in alphabetical order?</h3>
To evaluate the given probability; first, the number of possible arrangements is;
17P5 = 742,560 possible arrangements.
However, the chance of an alphabetical order arrangement in each case is; 1 out of 5! possible arrangements.
Hence, we have that the number of possible alphabetical arrangement is; (1/120) × 742,560 = 6188.
Hence, the required probability is; 6188/742,560 = 1/120
