First, I would write the problem vertically because it just helps me better.
7x+2y=10
-7x+1y=-16
Then, I would add downwards.
7x+2y=10
+ -7x+1y=-16
-------------------
0x+3y=-6
Now, divide 3 from both sides.
3y=-6
--- ---
3 3
y=-2
Now, plug in -2 for y in any equation to get x.
7x+2(-2)=10
Combine like terms
7x-4=10
Add 4 to both sides
7x-4=10
+4 +4
-------------
7x=14
Divide each side by 7.
7x=14
---- ---
7 7
x=2
So your solution is
(2,-2)
To check the solution, plug in the x and y values in both equations.
7(2)+2(-2)=10
14-4=10
10=10
-7(2)-2=(-16)
-14-2=-16
-16=-16
Therefore, the solution works.
<u>You must always plug in the x and y values into both equations to check the solution because sometimes the solution will work for one and not the other.</u>
The solution must work to both equations in other for it to be right.
Answer:
The only help I can give on this one is all the angles added up should be 180
Step-by-step explanation:
Hope this helps a bit :)
The rule of the payout annuity is

P is the initial amount
d is regular withdrawals
r is the annual rate in decimal
n is the number of periods in a year
t is the time
Since you have $500 000 saved, then
P = 500000
Since the interest is 8%, then
r = 8/100 = 0.08
Since the time is 15 years, then
t = 15
Since you want the monthly amount, then
n = 12
Substitute them in the rule to find d

Then you will be able to pull $4778.260422 each month
Answer:

Step-by-step explanation:
In order to find the measure of angle KMI, we need to note some angle relationships here.
GK and HJ are parallel lines cut by a transversal, meaning the angles formed by this transversal line will be the same along the parallel lines.
We know that the 29° angle is an alternate interior angle to KMI. This means their angle measures are the same.
Therefore, KMI is also 29°.
Hope this helped!
