Answer:
x = (-5 ± 2√10) / 3
Step-by-step explanation:
5 − 10x − 3x² = 0
Write in standard form:
-3x² − 10x + 5 = 0
Solve with quadratic formula:
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -(-10) ± √((-10)² − 4(-3)(5)) ] / 2(-3)
x = [ 10 ± √(100 + 60) ] / -6
x = (10 ± 4√10) / -6
x = (-5 ± 2√10) / 3

Answer:
$2,617.50
Step-by-step explanation:
Using this table, the tax is ...
tax = 2% × $3000 + 3% × (5000 -3000) + 5% × (17000 -5000) + ...
5.75% × (50,000 -17,000)
= $60 + 60 + 600 + 1897.50
tax = $2,617.50

<em>Additional comment</em>
Above $17,000, the tax is more easily computed as ...
tax = (5.75% × income) - 257.50
Each tax bracket can have a simplified formula like this.
