Answer:
-8 degrees
Step-by-step explanation:
-4 minus 7 degrees add 3 degrees
If you want to check if (1,2) is a solution to the system, you have to plug the x and y values back into both equations. If they work for one equation, but not the other, than the coordinates are not a solution to the system.
3(1) - 4(2) = -5
3 - 8 = -5
-5 = -5
2 = 4(1) - 2
2 = 4 - 2
2 = 2
Since both of these checks are true, then (1,2) is a solution to the system.
Answer:
x=-8, y=76/3
Step-by-step explanation:
I solved for substitution since I didn't know exactly what you're solving for.
<h3>The final amount is $ 6881.71</h3>
<em><u>Solution:</u></em>
<em><u>The formula for compound interest, including principal sum, is:</u></em>

Where,
A = the future value of the investment
P = the principal investment amount\
r = the annual interest rate in decimal
n = the number of times that interest is compounded per unit t
t = the time the money is invested
From given,
p = 4000
t = 5

n = 4 ( compounded quarterly )
<em><u>Substituting the values in formula,</u></em>

Thus the final amount is $ 6881.71
