Answer:
First you would take 5% of 4000. Add that to 6.5% of 6000. And then add that to 11% 3560(because that's the amount he earns over 10000). You should end up with $981.6
Subtract the 2nd row from the 1st row
5x = 5
Solve for x in the equation above
x = 1
Substitute x = 1 into any of the two equations above
Let's pick the first equation; 4x + 3y = -5
4 * 1 + 3y = -5
Solve for y in the equation above
y = -3
Therefore,
<u>x = 1</u>
<u>y = -3</u>
Answer:
none
Explanation:
Fill in each option for x individually.
I) 9
-10 - 4(-1)
II) 9
-10 - 4(-3)
III) 9
-10 - 4(-2)
Then, simplify the right side of each inequality.
I) 9
-6
II) 9
2
III) 9
-2
Each of these inequalities are flase. 9 is not less than or equal to any of these values, so the answer is none.
