Which ordered pair is a solution to the inequality? 4x + y > - 6

A) (1, -12)

B) (0, -9)

C) (-1, -1)

D) (-3, 0)

Answer:

Odd

Step-by-step explanation:

The graph intersects the x-axis three times. These three intercepts are the roots of the function and form the factors or solutions for x. They also represent the degree. This is an odd degree because there are 3 roots and 3 is odd. It is at least 3 but could be higher. All odd degree polynomials have the shape of a sideways s.

After all the deductions and exemptions, the total taxable​ income of Homer Simpson is $46,700.

Given that, income of Homer and his wife = $60000 and interest earned = $1200.

In mathematics, the tax calculation is related to the selling price and income of taxpayers. It is a charge imposed by the government on the citizens for the collection of funds for public welfare and expenditure activities. There are two types of taxes: direct tax and indirect tax.

Adding this to total income, we have total taxable amount = 60000+1200 = $61200

Now, investment in tax deferred savings plan = $2500

This amount will be subtracted from total taxable income, so amount becomes = 61200-2500 = $58700

Subtract the exemptions and deductions = $12000

That is, amount becomes = 58700-12000 = $46700

Hence, the net taxable income is $46,700.

Homer Simpson's taxable income is determined by subtracting his tax-deferred savings and total deductions from his total income. His taxable income comes to $46,700. The percentage of tax he pays depends on the U.S income tax bracket he falls under.

To calculate Homer Simpson's taxable income, we need to consider their total income, deductions, and investments. Homer's total income is the sum of his salary, $60,000 and the interest earned, $1200. So, the total income equals $60,000 + $1200 = $61,200.

Next, we subtract the total deductions which include the tax-deferred savings plan and the total deductions and exemptions they have, from the total income. Thus, the taxable income equals $61,200 - $2,500 (savings plan) - $12,000 (deductions and exemptions) = $46,700.

The U.S income tax code is based on a progressive system, so knowing the taxable income can help determine the income tax bracket Homer falls under. Given the figures, Homer's income is in the bracket that is taxed at 22% as per the 2020 basic tax tables from the Internal Revenue Service.  However, it is important to take into consideration any changes in tax laws or additional deductions they might have.

Answer:

x=-1

Step-by-step explanation:

x+3

------- = 3 + 1/x

x+2

Get a common denominator on the right

3*x/x + 1/x

3x/x + 1/x = (3x+1)/x

x+3       3x+1

------- = ---------

x+2         x

We can use cross products to solve

(x+3) *x = (3x+1) * (x+2)

x^2+3x = 3x*x +x + 3x*2 +2

Simplifying

x^2 + 3x = 3x^2 +7x+2

Subtract x^2 from each side

x^2 -x^2 + 3x = 3x^2-x^2 +7x+2

3x = 2x^2 +7x+2

Subtract 3x from each side

3x-3x = 2x^2 +7x -3x+2

0 = 2x^2 +4x +2

Divide by 2

Answer:

As long as the numbers are in equal proportion on the spinner, the probabilty of landing on an even number for the first and second spin is 1/4, or 25%.  

Step-by-step explanation:

If there are four numbers on a spinner, all in equal proportion, than the probability of getting an even number (either 4 or 6) on any spin is 2/4, or 1/2, which is also 50%.  Since the results of the first spin do not influence the results of the second spin, then they are independent events.  So, if the likelihood of landing on even each time is 1/2, then we would mutliply 1/2 by 1/2 in order to find the probability that landing on an even number would happen in both spins.  Our result would be 1/4, or 25%.

Answer:

b) 6

Step-by-step explanation:

Since this is an isosceles triangle, the two sides are equal and the two angles are equal.

That means  

5x-3 = 2x+15

Subtract 2x from each side.

5x-2x-3 = 2x-2x+15

3x-3 = 15

Add 3 to each side.

3x-3+3 = 15+3

3x =18

Divide each side by 3

3x/3 = 18/3

x =6

Answer: the answer to this question is A because the angle is acute angle and when you solve (5x-3) it equals up to 18 when you finish figureing it out.

Step-by-step explanation:

Answer:

BC - 54 units

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

∠C = 180° - (∠A + ∠B) = 180° - (80 + 50)° = 180° - 130° = 50°

Since ∠B = ∠C = 50° then the base angles of the triangle are equal hence the triangle is isosceles with

AB = AC, that is

4x - 4 = 2x + 16 ( subtract 2x from both sides )

2x - 4 = 16 ( add 4 to both sides )

2x = 20 ( divide both sides by 2 )

x = 10

⇒ BC = 5x + 4 = (5 × 10) + 4 = 50 + 4 = 54

The probability of 2 correct and 2 incorrect is (1/4)(1/4)(3/4)(3/4) = 9/256.

There are C(4,2) = 4·3/(2·1) = 6 ways to have some combination of 2 correct and 2 incorrect out of 4 questions. So, the probability of that result is ...

Answer:

<A = 67

Step-by-step explanation:

The three angles of a triangle add up to 180 degrees.  We know a right angle is 90 degrees.

<A + <B + <C = 180

3x-8 + 90 + x-2 =180

Combine like terms

4x-10+90 = 180

4x+80 =180

Subtract 80 from each side

4x+80-80=180-80

4x=100

Divide each side by 4

4x/4 = 100/4

x=25

But we want to know <A

<A = 3x-8

 Substitute x=25

    =3(25) -8

    =75-8

   = 67

Answer:

67°

Step-by-step explanation:

In a right triangle, the acute angles are complementary. That means that the sum of their measures is 90 deg.

m<A + m<C = 90

3x - 8 + x - 2 = 90

4x - 10 = 90

4x = 100

x = 25

m<A = 3x - 8

m<A = 3(25) - 8

m<A = 75 - 8

m<A = 67

Answer:

2/3

Step-by-step explanation:

A six-sided number cube labeled from 1 to 6 is rolled.

Total outcomes = 1,2,3,4,5,6= 6 outcomes

multiple of 2  are 2,4,6 so 3 outcomes

multiple of 3 are 3,6 so 2 outcomes

multiply of 2 or 3  are 2,4,3,6 so 4 outcomes

the probability of getting a multiple of 2 or a multiple of 3

= possible outcomes / total outcomes

= 4/6

now reduce the fraction, divide by 2 on both sides

the probability of getting a multiple of 2 or a multiple of 3 = 2/3

Tthe probability of rolling a multiple of 2 or a multiple of 3 on a six-sided die is [tex]\(\frac{5}{6}\)[/tex].

To find the probability of getting a multiple of 2 or a multiple of 3 when rolling a six-sided number cube, we can list out the possible outcomes and identify which ones satisfy our conditions.

The possible outcomes when rolling six-sided die are: 1, 2, 3, 4, 5, and 6:

Multiples of 2 on the die are: 2, 4, 6.

Multiples of 3 on the die are: 3, 6.

We can see that there is an overlap with the number 6, which is both a multiple of 2 and a multiple of 3. To avoid counting this outcome twice, we use the principle of inclusion-exclusion.

First, we add the number of multiples of 2 to the number of multiples of 3

- There are 3 multiples of 2.

- There are 2 multiples of 3.

So, without considering the overlap, we would have [tex]\(3 + 2 = 5\)[/tex] favorable outcomes.

However, since the number 6 has been counted twice, we subtract one instance of it from our total:

[tex]\(5 - 1 = 4\) unique favorable outcomes (2, 3, 4, 6)[/tex]

Since there are 6 possible outcomes in total when rolling a six-sided die, the probability of rolling a multiple of 2 or a multiple of 3 is the number of favorable outcomes divided by the total number of possible outcomes [tex]\(\frac{4}{6}\)[/tex].

This fraction simplifies to [tex]\(\frac{2}{3}\)[/tex]. However, we have overlooked the fact that every number on a six-sided die is a multiple of 1, and since 1 is neither a multiple of 2 nor of 3, it does not contribute to  favorable outcomes. Therefore, the only outcome that is not a multiple of 2 or 3 is number 1.

Thus, the correct probability is [tex]\(1 - \frac{1}{6} = \frac{5}{6}\)[/tex], since there is only 1 unfavorable outcome out of 6 possible outcomes.

Divide both sides by -3, and replace [tex]x^2[/tex] with [tex]y[/tex]. Then

[tex]-3x^4+27x^2+1200=0\iff y^2-9y-400=0[/tex]

Factorize the quadratic in [tex]y[/tex] to get

[tex]y^2-9y-400=(y+16)(y-25)=0\implies y=-16,y=25[/tex]

which in turn means

[tex]x^2=-16,x^2=25[/tex]

But [tex]x^2\ge0[/tex] for all real [tex]x[/tex], so we can ignore the first solution. This leaves us with

[tex]x^2=25\implies x=\pm\sqrt{25}=\pm5[/tex]

If we allow for any complex solution, then we can continue with the solution we ignored:

[tex]x^2=-16\implies x=\pm\sqrt{-16}=\pm i\sqrt{16}=\pm4i[/tex]

To find the markup from cost to sale price, calculate the original sale price by dividing the selling price by (1 - discount percentage) which is 230

To find the markup from cost to sale price, we first need to calculate the cost price.

The item is marked down by 20% from the selling price of $440.

So, the original sale price before the discount would be $440 / (1 - 0.20) = $550.

Since the sale price is still marked up from the cost of $320, we can calculate the markup as:

$550 - $320 = $230.

Final answer:

The unit rate, r, per day to keep the dog at the kennel is $14.25.

Explanation:

To find the unit rate, we need to divide the total cost by the number of days. In this case, Gene paid $171 to keep his dog at the kennel for 12 days. So the unit rate, which represents the cost per day, is calculated as:

Unit rate = Total cost / Number of days

Unit rate = $171 / 12

Unit rate = $14.25 per day which is the required answer

Therefore, unit rate to keep the dog at the kennel is $14.25 per day.

The perimeter of hexagon is 36 units.

A closed, two-dimensional polygon with six sides is what is known as a hexagon.

Six vertices and six angles make up a hexagon.

The words "hexa" and "gonio" both refer to six.

Regular hexagons have sides that are all the same length. Therefore, a regular hexagon's circumference is six times as long as its longest side.

Given the sides of Hexagon 2, 3, 2, 4, 7, and 6

the perimeter of hexagon is given by sum of all the sides,

and  a similar hexagon with two sides of length 3

the given hexagon have two same sides with length 2 units, so ae can change it by 3 units,

the length of hexagon is 3, a, 3, b, c, and d.

since hexagon are similar so the ratio of their length is also equal,

2/3 = 3/a = 2/3 = 4/b = 7/c = 6/d

solving rati we get a = 4.5, b = 6, c = 10.5 and d = 9

length of new hexagon is 3, 4.5, 3, 6, 10.5, 9

Perimeter = 3 + 4.5 + 3 + 6 + 10.5 +9 = 36 units.

Answer: 70

=====================================

Explanation:

The exterior angles (2x+12) and (2x) have corresponding interior angles 180-(2x+12) and 180-(2x)

Triangle ABC has the following interior angles

A = 112

B = 180 - 2x

C = 180 - (2x+12) = 180-2x-12 = 168-2x

Add up the interior angles for A,B,C and set the result equal to 180. Solve for x

A+B+C = 180

(112)+(180-2x)+(168-2x) = 180

112+180-2x+168-2x = 180

460-4x = 180

-4x = 180-460

-4x = -280

x = -280/(-4)

x = 70

---------------

Side note:

2x = 2*70 = 140 is the exterior angle for B, so 180-140 = 40 is the interior angle for angle B

2x+12 = 2*70+12 = 152 is the exterior angle for C, so 180 - 152 = 28 is the interior angle for C

Add up the interior angles to find that A+B+C = 112+40+28 = 180, so this helps confirm we have the right x value.

Therefore, hang time of the basketball player is 0.83 sec.

Answer: There are 6 sections of  [tex]8\frac{1}{4}\ inches[/tex]  of rope Mario can cut from the rope .

Step-by-step explanation:

Since we have given that

Length of the rope for the tent = 7 feet

As we know that

[tex]1\ feet=12\ inches\\\\7\ feet=12\times 7=84\ inches[/tex]

Length of rope is used to tie a tarp on top of the tent = 34.5 inches

Remaining length of rope is given by

[tex]84-34.5=49.5\ inches[/tex]

According to question, the remaining rope should be cut into

[tex]8\frac{1}{4}\ inches\\\\=\frac{33}{4}\ inches[/tex]

So, Number of  [tex]8\frac{1}{4}\ inches[/tex] sections of rope Mario can cut from the rope is given by

[tex]\frac{49.5}{8\frac{1}{4}}\\\\=\frac{49.5}{\frac{33}{4}}\\\\=\frac{49.5\times 4}{33}\\\\=6[/tex]

Hence, there are 6 sections of [tex]8\frac{1}{4}\ inches[/tex] rope Mario can cut from the rope .

Answer:

6

Step-by-step explanation:

Mario has 7 feet of rope.  Since there are 12 inches in every foot, this means he has

7(12) = 84 inches of rope.

34.5 inches of the rope must be used to tie the tarp to the top; this leaves Mario with

84-34.5 = 49.5

This remaining rope will be cut into 8 1/4 inch sections.  We can also write 8 1/4 as 8.25.  To find the number of sections this length he can cut, we divide:

49.5/8.25 = 6

He can cut 6 sections this length.
