Answer:

x = 1

Step-by-step explanation:

4(2x-1)+8-14= -8x+ 4+ 2x

To solve 12x÷4y, first, let's evaluate the products on both sides of the ÷ symbol, we know that x = -8, then we have:

We have -96 on the left side of the ÷ symbol.

We know that y = 3, then, on the right side, we have:

Then, we have 12 on the right side of the ÷ symbol, now the expression looks like this:

-96 ÷ 12. what we have to do is to divide -96 by 12, then we get:

Then, the answer is 8

We need to obtain the first derivate

Answer: B on edge23

Step-by-step explanation:

f(x) = 1/2^x2–4x + 5

Determine whether is a solution for:

For, x=-8, y has to be 3:

(-8, 3) is not a solution for the equation.

For x=-4, y has to be -1:

(-4, -1) is a solution for the equation.

For x=6, y has to be -7:

(6, -7) is a solution for the equation.

For x=7, y has to be 2

(7, 2) is not a solution for the equation.

The practical domain is 1 ≤ x ≤ 20 and the practical range is 13.61 ≤ C(x) ≤ 127.61

From the question, the given parameters are:

The domain is dependent on the number of windows washed

Using the maximum as a guide, the minimum number of windows could be

Minimum = 1

The domain is then represented as

Minimum ≤ x ≤ Maximum

So, we have

1 ≤ x ≤ 20

Using the given parameters in (a), we have

Total cost, C = Charges * Number of windows + Reservation

So, we have

C(x) = 7.61 + 6x

Where x is the number of windows

When x = 0, we have

C(1) = 7.61 + 6(1)

C(1) = 13.61

When x = 20, we have

C(20) = 7.61 + 6(20)

C(20) = 127.61

So, we have the range to be 13.61 ≤ C(x) ≤ 127.61

We are given three angles and we are asked to determine if the angles are the angles of a triangle. To do that we need to have into account that the measure of the angles of a triangle always adds up to 180, therefore, if we add up the angles and the result is 180, then these angles can be angles measures of a triangle. If the result is different from 180 the angles can't be the angle measures of a triangle. Taking the first set of three angles we get:

Since the result is different from 180 then these angles can't be the angle measure of a triangle.

The same procedure is used to determine the other sets of angles.

the option D is the correct answer

We are given the following information:

Table sides = 36 inches & 18 inches

Diagonal of table = 43 inches

We are to find out if the table is "square" (that is if the table follows the Pythagoras theorem). We will check this below:

Therefore, the table is not "square" (it does not have right angles at the corners)

Net worth is equal to total assets minus total liabilities (debt).

So,

Total Assets = 253000

Total Liabilities = 216345

Hence,

Net Worth = 253000 - 216345 = $36,655

we have that

44/13=3.38

rounded to the nearest tenths

3.38=3.4

Okay, here we have this:

Considering the provided information we obtain the following:

Replacing in the Compound Interest formula we obtain the following:

b)

After 1 year (t=1):

We obtain that after one year the balance is aproximately $17,161.06.

After 2 years (t=2):

We obtain that after two years the balance is aproximately $18,331.90

After 5 years (t=5):

We obtain that after five years the balance is aproximately $22,345.90.

After 10 years (t=10):

We obtain that after ten years the balance is aproximately $31,082.44.

c)

In this case the doubling time will be when she has double what she initially had, that is: $16,065*2=$32130, replacing in the formula:

Let's solve for t:

Finally we obtain that the doubling time is approximately 10.502 years or about 10 years 6 months.

Triangulation means the measuring of distances in surveys with triangles. If the distance of two objects and the angle between is knwon, the distance between these objects can be calculated.

Given the diagram we have:

So, the distance between both objects will be calculated by:

Where:

Distance to the first object a = 6

Distance to the first object b = 6

Angle between both objects θ = 60°

Substitute the values, we have:

Simplify:

So, the distance between both objects c = 6 inches

And a scale factor of a dilated image is

If the perimeter of M'N'O'P' = y

Then

Cross multiplying,

The perimeter of M'N'O'P' = 7/8 x units

Option A is correct

To solve the problem, we notice that both of the equations are written with the y solved then we can equate the expressions of x and solve the resulting equation of x:

Once we have the value of x we plug it on the first equation to find y:

The area of right triangle is [tex]\frac{1}{15}[/tex].

The given coordinates are [tex](-2,-1), (1, 1), (3,-2)[/tex].

We have to find the area of right triangle.

To find the area we first draw the graph using that coordinate.

The graph of the coordinate is

To find the area we use the formula

[tex]\angle ABC=\frac{1}{2}(|AB|)(|AC|)[/tex]

We first find the value of [tex](|AB|)[/tex] and [tex](|AC|)[/tex].

e coordinate of [tex]A[/tex] is [tex](-2,-1)[/tex] and [tex]B[/tex] is [tex](1,1)[/tex].

The slope of [tex](|AB|)=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

The slope of [tex](|AB|)=\frac{1-(-1)}{1-(-2)}[/tex]

The slope of [tex](|AB|)=\frac{1+1}{1+2}[/tex]

The slope of [tex](|AB|)=\frac{2}{3}[/tex]

The coordinate of [tex]A[/tex] is [tex](-2,-1)[/tex] and [tex]C[/tex] is [tex](3,-2)[/tex].

The slope of [tex](|AC|)=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

The slope of [tex](|AC|)=\frac{(-2)-(-1)}{3-(-2)}[/tex]

The slope of [tex](|AC|)=\frac{-2+1}{3+2}[/tex]

The slope of [tex](|AC|)=-\frac{1}{5}[/tex]

Now finding the area of right triangle by putting the values.

[tex]\angle ABC=\frac{1}{2}\times\frac{2}{3} \times(-\frac{1}{5})[/tex]

Area can't be negative so

[tex]\angle ABC=\frac{1}{2}\times\frac{2}{3} \times\frac{1}{5}\\\angle ABC=\frac{2}{30}\\\angle ABC=\frac{1}{15}[/tex]

Hence, the area of right triangle is [tex]\frac{1}{15}[/tex].
