Answer:
The graph shows the solution of the inequality y > x - 2 ⇒ D
Step-by-step explanation:
In the inequality,
- If the sign of inequality is ≤ or ≥, then the line that represents it must be a solid line
- If the sign of inequality is < or >, then the line that represents it must be a dashed line
- If the sign of inequality is > or ≥, then the shaded area must be over the line
- If the sign of inequality is < or ≤, then the shaded area must be under the line
From the given graph
∵ The slope of the line = =
=
=
∵ The y-intercept is (0, -2)
∵ The line is dashed and the shaded area is over the line
→ By using the 2nd and 3rd notes above, the line is dashed and
the sign of inequality is >
∴ The inequality is y > x - 2
∴ The graph shows the solution of the inequality y > x - 2
Answer:
(a) Ebony's taxable income = $42,540
(b) Amount of tax due = $5190.3
(c) Amount of tax owed = $4810.3
Step-by-step explanation:
Ebony's gross income = $46,660 (given)
Allowable tax deductions = $4,120 (given)
(a) Taxable Income = Gross income - Tax deductions
Ebony's taxable income = $46,660 - $4,120
Ebony's taxable income = $42,540
(b) Amount of tax due = 22% of Taxable Income,
Refer to the USA Tax Brackets for 2019 (See Attached image)
Amount of tax due = 10% on first $9,700 + 12% on ($39475-$9700) + 22% on ($42540-$39475).
Amount of tax due = 10% on first $9,700 + 12% on $29775 + 22% on $3065.
Amount of tax due = $970 + $3573 + $647.3
Amount of tax due = $5190.3
(c) Ebony pays $95 per week in tax. In four weeks (a month), she'd pay
$95 * 4 = $380
Amount of tax owed = Amount of tax due - Amount of tax paid
Amount of tax owed = $5190.3 - $380 = $4810.3
