Answer:
The solution is: (2, -1)
Step-by-step explanation:
First we rewrite the second system equation
→ 
Now we have the following system of equations:
To solve the system multiply the first equation by -3 and add it to the second equation
--------------------------------------
Now we substitute the value of y in the first equation and solve for x
The solution is: (2, -1)
Answer: 20%
100 shares at $45each cost 100*45 = $4500
After a year, he sold the share at the rate if $52 each and it cost 52*100 = 5200
He received dividend of $2 on each dollars meaning 100*2 = $200
So,
$5200+200 = 5400
Profit = $5400 - 4500 = 900
%profit = 900*100 / 4500 = 20
Answer:
Step-by-step explanation:
Half
50 percent.
1 divided by 2?
(2 3/8)/(1 1/2) = (19/8)/(3/2) = (19/8)*(2/3) = 19/12
(9 1/2)/6 = (17/2)/6 = 17/12
17/12 ≠ 19/12
The two pairs of numbers are NOT proportional.
Answer: False
Step-by-step explanation:
There is a very easy way to tell whether an ordered pair is a function or not. If many x's have one y, then it is not a function. Since (-1,7) and (-7, 7) both have the same y, it is not a function. Hope this helps!
