These lines are perpendicular!
y = x
y = -x–2
The slopes are reciprocals of each other, so they are perpendicular.
Breaking apart means that you just take the tens from each number, and the ones from each number, then add them up.
The tens from your numbers are:
30 from 34
40 from 45
The ones from your numbers are:
4 from 34
5 from 45
Now, you have to add up the tens and ones separately.
30 + 40 = 70
4 + 5 = 9
Finally, you add up those 2 numbers that you got- 70 and 9

Answer:
$2353 at 12.5% and $7647 at 8.25%
Step-by-step explanation:
I'll say a is the amount he invested in one market, and b is the amount in the other.
a + b = 10000, or b = 10000 - a
multiplying the investments with the percentages and adding them together will give the total earned interest.
(a × 0.125) + (b × 0.0825) = 925
0.125a + 0.0825b = 925
Use substitution to solve for a.
0.125a + 0.0825(10000 - a) = 925
0.125 a + 825 - 0.0825a = 925
0.0425a = 100
a = 2352.94
Use substitution to find b
b = 10000 - 2352.94
b = 7647.06
The questions are to the nearest dollar so round a and b.
$2353 and $7647
The equation is (X+9)+6=5
