2x - y = -2 . . . (1)
5x - 2y = -7 . . . (2)
From (1), y = 2x + 2 . . . (3)
Putting (3) into (2), gives:
5x - 2(2x + 2) = -7
5x - 4x - 4 = -7
x - 4 = -7
x = -7 + 4 = -3
y = 2(-3) + 2 = -6 + 2 = -4.
Therefore, the required answer is (-3, -4)
Answer:
The stock is worth $702.5.
Step-by-step explanation:
Giving the following information:
Present Value= $500
Number of periods (n)= 3 years
Growth rate (i)= 12%
<u>To calculate the value of the stock today, we need to use the following formula:</u>
FV= PV*(1+i)^n
FV= 500*(1.12^3)
FV= $702.5
The stock is worth $702.5.

Answer:
44.36
Step-by-step explanation:
44.3551 ~ 44.36
Note: 2 decimal places is something like 9.55, 10.67 and etc. If your using 44.3551 to find out how to round off to two decimal places, focus on the 51 at the back of the number since that will be excluded from the answer.
