What is the solution to this equation?

4x - 6 + 2x = 18

Answer:

$82,250 < x <= $171,550

Step-by-step explanation:

You didn't provide all the possible answers.  In this case we don't need to see all answers to help you... but because you didn't provide all the choices for answer, we can't give the exact answer, only the possible range of values.

The question asks for a possible taxable income for someone filing under the 28% bracket.

If we look at the table, we see the 28% bracket is for income ranging from $82,250 (exclusively) to $171,550 (inclusively)

So, your answer has to be within the range:

$82,250 < x <= $171,550

It cannot be $82,250 but it can be $171,550 and any number in between.

Since you didn't provide all the answer choices, we can't tell you if it's B, C, D, and so on... but we can tell you it's not A.

Answer:

Last option

Step-by-step explanation:

Given expression is:

[tex]\sqrt{\frac{128x^5y^6}{2x^7y^5} }[/tex]

The terms can be simplified one by one

[tex]=\sqrt{\frac{64x^5y^6}{x^7y^5} }[/tex]

As the larger power of x is in numerator, the smaller power will be brought to denominator

[tex]=\sqrt{\frac{64y^6}{x^{(7-5)}y^5}}\\=\sqrt{\frac{64y^6}{x^{2}y^5}}[/tex]

Similarly for y,

[tex]=\sqrt{\frac{64y^{(6-5)}}{x^{2}}}\\=\sqrt{\frac{64y}{x^{2}}}[/tex]

Applying the radical

[tex]\sqrt{\frac{8^2*y}{x^{2}}}\\So\ the\ answer\ will\ be\\= \frac{8\sqrt{y}}{x}[/tex]

So, last option is the correct answer ..

Answer: Last option.

Step-by-step explanation:

You need to apply the Quotient of powers property:

[tex]\frac{a^m}{a^n} =a^{(m-n)}[/tex]

Then:

[tex]\sqrt{\frac{128x^5y^6}{2x^7y^5}} =\sqrt{\frac{64y}{x^2}}[/tex]

Remember that:

[tex]64=8*8=8^2[/tex]

Then you can rewrite the expression:

[tex]=\sqrt{\frac{8^2y}{x^2}}[/tex]

Finally, since [tex]\sqrt[n]{a^n}=a[/tex], you get:

Step-by-step explanation:

If (p, 0) and (q, 0) are x-intercepts, then p and q are zeros.

The intercept form of an equation of a quadratic function:

y = a(x - p)(x - q)

p, q - x-intercepts (zeros).

We have the equation: y = 2(x + 4)(x - 6) = 2(x - (-4))(x - 6)

Therefore the x-intercepts are -4 and 6.

The zeros are -4 and 6 too.

The measure of angle BC of the triangle is given by BC = 130°

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔBCD , where it is isosceles

And , the measure of BC ≅ BD

where Isosceles triangle C B D has points on the circle.

The measure of arc CD = 100°

Now , arc length is twice the inscribed angle.

2 x ∠B = CD

2 x ∠B = 100

∠B = 100/2

∠B = 50

Now, in an isosceles triangle, the angle opposite to the equal sides must be equal.

The sum of the three angles must be 180.

x + x + 50 = 180°

2x = 180 - 150

2x = 130°

Hence , the measure of angle BC = 130°

Answer:

C. 10 units

Step-by-step explanation:

The half diagonals of a rhombus are the legs of a right triangle with the hypotenuse being the side of the rhombus.

EG and FH are the diagonals of the rhombus. The half-diagonals measure 8 and 6.

We can use the Pythagorean theorem to find the hypotenuse length with is the length of the side of the rhombus.

a^2 + b^2 = c^2

8^2 + 6^2 = c^2

64 + 36 = c^2

100 = c^2

c^2 = 100

c = 10

Answer: 10 units

The length of one side of the rhombus is 10 units.

A rhombus is a two dimensional shape which consists of four equal sides with opposite side being parallel and opposite angles being equal.

Given that,

EFGH is a rhombus.

Length of the two diagonals are also given.

EG = 16 and FH = 12

In a rhombus, the diagonals bisect each other at right angles.

Let the intersection point of the diagonals be O.

Consider ΔOFG.

Using Pythagoras Theorem,

(FG)² = (OG)² + (OF)²

OG = EG / 2 = 16 / 2 = 8

OF = FH / 2 = 12 / 2 = 6

(FG)² = 8² + 6²

        = 100

FG = √100 = 10

Hence the length of one side of the rhombus is 10 units.

f ^-1 (x) = 2x+28

Step-by-step explanation:

f(x) = 1/2x-14

Replace f(x) with y

y = 1/2 x -14

Exchange x and y

x = 1/2 y -14

Solve for y

Add 14 to each side

Step-by-step explanation:

When you flip the points of the function, you have:

(2,1) (4,3) (6,5) (8,7)

Each x value has its own y value, so it is a function

Option D is correct. The inverse of the given function is a function since all the element in its co-domain has a unique element in the domain.

For a mapping to be called a function, it must have but the input values called the domain and the output values known as the co-domain.

All the domains must also have a corresponding co-domain, else it is not a function.

From the given mapping, we can see that all the values in the domain have corresponding values in the co-domain and vice versa(in the case of its inverse).

Hence we can conclude that the inverse of the given function is a function making other options incorrect.

Final answer:

The explicit formula for the sequence 2, 6, 18, 54, 162, ... is [tex]an = 2 imes 3^(n-1),[/tex] where an represents the nth term of the sequence.

Explanation:

The sequence given is 2, 6, 18, 54, 162, ..., which can be recognized as a geometric sequence. In a geometric sequence, each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio (r). To find the explicit formula for the nth term of a geometric sequence, we use the formula an = a1  imes r(n-1), where a1 is the first term and r is the common ratio.

Looking at our sequence, the first term a1 is 2. The common ratio r can be found by dividing the second term by the first term (or any term by the previous term), which is 6/2 = 3. Now that we have both the first term and the common ratio, we can plug these values into our formula to get the explicit formula for the nth term of the sequence: an = 2  imes 3(n-1).

Final answer:

The function f(x) = 2x^3 – x^2 – 6x is found by factoring the function, resulting in the zeros at x = 0, x = -3/2, and x = 2.

Explanation:

To find the zeros of the function f(x) = 2x^3 – x^2 – 6x, we must set the function equal to zero and solve for x. If possible, this can be done by factoring the function or using synthetic division. In this case, the function can be factored by taking out a common factor of x:

f(x) = x(2x^2 - x - 6) = 0

Next, we can factor the quadratic equation 2x^2 - x - 6 to find the remaining zeros:

2x^2 - x - 6 = (2x + 3)(x - 2)

This gives us the following zeros for the function:

x = 0

x = -3/2

x = 2

Therefore, f(x) has three zeros: 0, -1.5 (or -3/2), and 2.

Step-by-step explanation:

(1 - 37%)(x) = 59

(0.63)(x) = 59

x = 93.65

Final answer:

To find the original price of the printer before a 37% discount, we set up an equation and solve for the original price. After solving, the original price is found to be approximately $93.65.

Explanation:

To calculate the original price of the printer before the discount, we need to understand that the sale price represents 100% - the discount percentage of the original price. Given that the sale price is $59 after a 37% discount, we set up an equation where the original price (which we'll call P) minus 37% of P equals $59.

The equation looks like this: P - 0.37P = $59. We can simplify this equation by combining like terms, which gives us 0.63P = $59. To find P, we then divide both sides of the equation by 0.63, leading us to the original price.

Let's do the math:

The original price of the printer is calculated to be approximately $93.65.

Step -2 In ΔDBC and ΔADC (from figure).

∠DCB=∠ACD (common in both triangles) ,

∠DBC=∠ADC =90 degree, and

∠CDB=∠CAD (rest angle of the two triangles).

therefore ΔDBC similar to ΔADC (by AAA similarity theorem).
