Answer:

x = -4

Step-by-step explanation:

Distribute 2 inside the parentheses

[tex]2\times x = 2x\\ 2\times2=4\\ 2x+4 - 4[/tex]

Combine like terms

[tex]-4x + 2x = -2x + 4 = 12[/tex]

Subtract 4 from both sides

-2x = 8

x = -4

The solution of the linear equation 2(x + 2) – 4x = 12 will be negative 4.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given below.

2(x + 2) - 4x = 12

Solve for x in the equation 2(x + 2) - 4x = 12. Then we have

2(x + 2) - 4x = 12

2x + 4 - 4x = 12

-2x = 12 - 4

-2x = 8

x = -8/2

x = -4

The solution of the linear equation 2(x + 2) – 4x = 12 will be negative 4.

Answer:

(-10, -8) and (-6, -4)

Step-by-step explanation:

we know that

The diagonals of a rhombus are perpendicular

If two lines are perpendicular, then the product of their slopes is equal to -1

m1*m2=-1

step 1

Find the slope of the given diagonal

we have

(-11, -9) and (-5, -3)

m=(-3+9)/(-5+11)

m=-6/6=-1

Find the slope of the other diagonal

we have

m1=-1

Find m2

m1*m2=-1

(-1)*m2=-1

m2=1

step 2

Verify the slope of each of the endpoints of the other diagonal

The slope of the other diagonal must be equal to 1

so

case a) (-10, -4) and (-6, -8)

m=(-8+4)/(-6+10)

m=-4/4=-1

therefore

The points of case a) cannot be the end-points of the other diagonal

case b) (-8, -3) and (-5, -6)

m=(-6+3)/(-5+8)

m=-3/3=-1

therefore

The points of case b) cannot be the end-points of the other diagonal

case c) (-8, -4) and (-8, -8)

m=(-8+4)/(-8+8)

m=-4/0 -----> undefined

therefore

The points of case c) cannot be the end-points of the other diagonal

case d) (-10, -8) and (-6, -4)

m=(-4+8)/(-6+10)

m=4/4=1

therefore

The points of case d) can be the end-points of the other diagonal

Answer:

[tex]70ft^2[/tex]

Step-by-step explanation:

Surface area is the sum of all sides of the area. Since it is a rectangular prism, each surface area will be multiplied by two to account for the opposite side (ex. top and bottom are the same area).

The front/back area is [tex]1*11[/tex] or 11. So the sum of the areas is 22.

The right/left area is [tex]2*1[/tex] or 2. So the sum of the areas is 4.

The top/bottom area is [tex]2*11[/tex] or 22. So the sum of the areas if 44.

We add these together to find the surface area.

[tex]22+4+44=70[/tex]

The surface area is [tex]70ft^2[/tex]

Answer:

A) -sqrt(3)/3

Step-by-step explanation:

If you know your unit circle (attached), 11pi/6 has the value of (sqrt(3)/2,-1/2), where the coords are (cosine, sine).

Tangent is sine/cosine:

(-1/2)/(sqrt(3)/2)

We can convert this to multiplication by miltiplying the reciprocal of sqrt(3)/2:

(-1/2)*(2/sqrt(3))

Multiplied out to:

-2/(2sqrt(3))

We have to rationalize this by multiplying the numerator and denominator by sqrt(3):

-2(sqrt(3))/2sqrt(3)(sqrt(3)

two of the same square roots multiplied together equals the number without the sqrt:

-2(sqrt(3))/2*3

we can factor out 2 from the numerator and denominator:

-sqrt(3)/3

Therefore, the answer is A

Answer:

The equation 0 = ax2 + bx + c has no real roots or no solution.

Step-by-step explanation:

We are told that the graph of y = ax2 + bx + c is a parabola that opens up and has a vertex at (0, 5). Since the parabola opens up, the vertex (0, 5) will be the lowest point on the graph of the function. This implies that the parabola does not intersect the x-axis; the line y = 0. Therefore, the equation;

To solve this problem use the properties of the logarithms.

We know that the inverse function of [tex]y = log_2 (x)[/tex] is [tex]y = 2 ^ x[/tex].

So when composing the function with its inverse function we have to:

[tex]2 ^ {log_2 (x)} = x[/tex].

Answer:

[tex]\frac{1}{a(a-4)}[/tex]

Step-by-step explanation:

Factor the denominator of the first fraction

a² - 16 ← is a difference of squares and factors as

a² - 16 = (a - 4)(a + 4), thus fraction becomes

[tex]\frac{a}{(a-4)(a+4)}[/tex] × [tex]\frac{a+4}{a^2}[/tex]

Cancel the factor (a + 4) on numerator/denominator and the a and a², leaving

[tex]\frac{1}{a(a-4)}[/tex]

Answer:

First, we need to find the missing side which is BC ( using pythagorean theorem)

AB² + BC² = AC²

=> 16² + BC² = 20²

=> BC²          = 20² - 16² = 144

=> BC           = √144 = 12

Now apply the formulars:

Just to make things easier, let's point out exactly what will the hypotenuse, opposite side and adjacent side.

So in this case:

The hypotenuse will be AC

The opposite side (of angle A) is BC

The adjacent side (of angle A) is AB

Therefore:

sin A = opposite/hypotenuse = BC/AC = 12/20 = 3/5

cos A = adjacent/hypotenuse = AB/AC = 16/20 = 4/5

tan A = opposite/adjacent = BC/AB = 12/16 = 3/4

Answer:

They have the same slope but different y-intercepts, so they have no solution.

Step-by-step explanation:

As the slopes are the same (2) but the y-intercepts are different, it means that the straights are parallel. Parallel equations have no solution as the straights don't intercept each other.

Answer: They have the same slope but different y-intercepts, so they have no solution.

The given equations are [tex]y=2x+\frac{1}{4}[/tex] and [tex]y=2x-\frac{1}{4}[/tex].

We compare them with y = mx + b.

So the slope of both of them is m=2.

y-intercept for the first one is = b = 1/4

y-intercept for the second one is = b = -1/4

Hence, the lines are parallel and will never meet and will have no solution.

Answer:

y = (-6/7)x + 11/7

Step-by-step explanation:

Going from  (-4, 5)  to  (3,-1), x increases by 7 and y decreases by 6.  Hence, the slope, m, of this line is m = rise / run = -6/7.

Making use of the slope-intercept form of the equation of a str. line, we have:

y = mx + b  →   5 = (-6/7)(-4) + b, or

                        5 = 24/7 + b.  Thus, b = 11/7, and

y = (-6/7)x + 11/7

The formula to find slope when you know two points is

Answer:

There are 20 vertices in the polyhedron.

The number of vertices in a polyhedron can be determined using Euler's formula or the specific properties of certain polyhedra such as platonic solids. The number of vertices varies depending on the type and structure of the polyhedron.

The number of vertices in a given polyhedron depends on the specific characteristics of the shape. According to the Euler's formula, represented as V - E + F = 2 (where V is the number of vertices, E the number of edges, and F the number of faces), we can determine the number of vertices if the other values are known.

For instance, a tetrahedron has 4 vertices, an octahedron has 6, a icosahedron has 12, a cube (also known as a regular hexahedron) has 8, and a dodecahedron has 20 vertices.

Answer:

Since the money appreciates 4.2% each year, then:

2000=1600x(1.042)^n, where n is the number of years

Then:

1.25=1.042^n

ln 1.25=ln 1.042^n=n ln 1.042

n=5.424 years

Cate's $1600 stock investment, growing at 4.2% annually, will take approximately 5.21 years to reach a value of about $2000.

Given that Cate purchases $1600 worth of stock with an estimated increase in value by 4.2% each year, we are looking to find out after how many years the value will be about $2000. To determine this, we can use the formula for exponential growth, P = P_0 (1 + r)^t, where P is the future value, P_0 is the initial value, r is the rate of increase, and t is the time in years.

Cate's initial investment is $1600 (P_0), and we aim for a future value of $2000 (P). The annual growth rate r is 4.2%, or 0.042 when expressed as a decimal. Plugging these values into the formula and solving for t gives us:

So, it will take approximately 5.21 years for Cate's investment to reach a value of about $2000, assuming a steady 4.2% growth rate.

The equation will be like this: y=ax+c. a is the slope and c is where the line crosses the (vertical) y axis - AKA the y-intercept.

As for the slope, it can be found like [(8-3)/(2-1)]. That gives 5. Another way to see it is to notice that between (1,3) and (2,8), the line moved up 5 points and went to the right only 1.

And for the y-intercept, make the equation y = 5x + c. Solve for c by filling x and y with information from any of the two points. Let's choose (1,3). Plugging in gives the equation 3=5(1)+c. C equals -2.

So, the final equation is:

y = 5x - 2

Answer:

y - 3 = 5(x - 1)

Step-by-step explanation:

Slope:  as we move from (1, 3) to (2, 8), x increases by 1 and y increases by 5.  Hence, the slope of this line is m = rise / run = 5/1, or just m = 5.

In point-slope form, the pertinent equation is

y - 3 = 5(x - 1)

Answer: -2,4

Step-by-step explanation:

Center = (-2,4) are the coordinates of the center of the ellipse .

The major and minor axes' midpoints meet at the center of an ellipse. At their intersection, the axes are perpendicular. The foci are always on the major axis, and the constant sum of the distances between the foci is greater than the sum of the distances from the foci to any point on the ellipse.

The equation of an ellipse is [tex]\frac{\left(x - h\right)^{2}}{a^{2}} + \frac{\left(y - k\right)^{2}}{b^{2}} = 1[/tex]

where (h,k) is the center, b and a are the lengths of the semi-major and the semi-minor axes.

Our ellipse in this form is [tex]\frac{\left(x - \left(-2\right)\right)^{2}}{9} + \frac{\left(y - 4\right)^{2}}{36} = 1[/tex]

Thus, h = -2, k = 4

Center = (-2,4).
