Answer:Some equations may not have solutions and some may have one or more than one is because of the variables or how they are written

Step-by-step explanation:not 100% sure this is the correct answer,I tried my best.

A system of equations consists on a group of equations that we must solve at the same time.

From this, the solutions of a system of equations appear as the intersections between the graphs of the equations that conform the system.

So for example, if a system has two parallel lines (two lines that never intersect) that system will have no solution.

If a system has two different and not parallel lines, these lines will intersect at some point, so this system will have one solution.

And finally, if the system has twice the same line, the graphs of the lines will intersect in infinite points, thus, this system has infinite solutions.

Answer:

its answer is 17 first find p and q value then use x2-x1 y2-y1 formula

The absolute value equation is:

|x + 1.3| = x  + 1.3

The absolute value equation that we have is:

|x - b| = c

And we want that the solution set is all the numbers larger than -1.3

Now, remember that:

| something|  ≥ 0.

So the absolute value is always equal or larger than zero.

So, for example, the equation:

|x| = x

Only is true if x ≥ 0, because if x is smaller than zero, for example x = -2, we would have:

|-2| = -2

2 = -2

Which is false.

Now we want to have solutions larger than -1.3 instead of larger than zero, so we can write:

|x  + 1.3| = x + 1.3

The solution of this equation is the given set.

Answer:

option B shows the correct solution.

Find y-intercept:

3y - 4x = -3

3y - 4(0) = -3

3y = -3

y = -1

Find x-intercept:

3y - 4x = -3

3(0) - 4x = -3

-4x = -3

x = 3/4

Check option B

Answer:

[tex]3\sqrt{6}+3\sqrt{2}i[/tex] and [tex]-3\sqrt{6}-3\sqrt{2}i[/tex]

Step-by-step explanation:

For a complex number [tex]z=a+bi[/tex] in rectangular form, polar form is [tex]z=r[cos(\theta)+isin(\theta)][/tex] where [tex]r=\sqrt{a^2+b^2}[/tex] and [tex]\theta=tan^{-1}(\frac{b}{a})[/tex]:

[tex]r=\sqrt{a^2+b^2}\\\\r=\sqrt{(36)^2+(36\sqrt{3})^2}\\\\r=\sqrt{1296+3888}\\\\r=\sqrt{5184}\\\\r=72[/tex]

[tex]\theta=tan^{-1}(\frac{b}{a})\\ \\\theta=tan^{-1}(\frac{36\sqrt{3}}{36})\\ \\\theta=tan^{-1}(\sqrt{3})\\\\\theta=\frac{\pi}{3}[/tex]

Thus, our complex number in polar form is [tex]z=72[cos(\frac{\pi}{3})+isin(\frac{\pi}{3})][/tex]. This will help us determine the square roots of the complex number using the formula [tex]\sqrt[n]{r}\biggr[cis\bigr({\frac{\theta+2\pi k}{n})\biggr][/tex] for [tex]k=0,1,2,\: ... \:,n-1[/tex]. Note that [tex]cis(\theta)=cos(\theta)+isin(\theta)[/tex]:

1st square root for k = 2-1 = 1

[tex]\sqrt[n]{r}\biggr[cis\bigr({\frac{\theta+2\pi k}{n})\biggr][/tex]

[tex]\sqrt[2]{72}\biggr[cis\bigr({\frac{\frac{\pi}{3}+2\pi(1)}{2})\biggr][/tex]

[tex]6\sqrt{2}\biggr[cis\bigr({\frac{\frac{\pi}{3}+2\pi}{2})\biggr][/tex]

[tex]6\sqrt{2}\biggr[cis\bigr(\frac{\pi}{6}+\pi)\biggr][/tex]

[tex]6\sqrt{2}\biggr[cis\bigr(\frac{7\pi}{6})\biggr][/tex]

[tex]6\sqrt{2}\biggr[cos(\frac{7\pi}{6})+isin(\frac{7\pi}{6})\biggr]\\ \\6\sqrt{2}(-\frac{\sqrt{3}}{2}-\frac{1}{2}i)\\\\-3\sqrt{6}-3\sqrt{2}i[/tex]

2nd square root for k = 1-1 = 0

[tex]\sqrt[6]{72}\biggr[cis\bigr({\frac{\frac{\pi}{3}+2\pi(0)}{2}\bigr)\biggr][/tex]

[tex]6\sqrt{2}\biggr[cis(\frac{\pi}{6} )\biggr][/tex]

[tex]6\sqrt{2}[cos(\frac{\pi}{6})+isin(\frac{\pi}{6})]\\ \\6\sqrt{2}(\frac{\sqrt{3}}{2}+\frac{1}{2})\\\\3\sqrt{6}+3\sqrt{2}i[/tex]

Therefore, the square roots of [tex]36+36\sqrt{3}i[/tex] are [tex]3\sqrt{6}+3\sqrt{2}i[/tex] and [tex]-3\sqrt{6}-3\sqrt{2}i[/tex].

Answer:

a = side length a

b = side length b = bottom triangle base b

c = side length c

h = height of prism

H = height of bottom triangle

V = volume

Atot = total surface area = all sides

Alat = lateral surface area = all rectangular sides

Atop = top surface area = top triangle

Abot = bottom surface area = bottom triangle

A triangular prism is a geometric solid shape with a triangle as its base. It's a three-sided prism where the base and top are equal triangles and the remaining 3 sides are rectangles.

Triangular Prism Formulas in terms of height and triangle side lengths a, b and c:

Volume of a Triangular Prism Formula

Finds the 3-dimensional space occupied by a triangular prism.

V=14h(c+a−b)(a+b−c)−−−−−−−−−−−−−−−−−√×(a+b+c)(b+c−a)−−−−−−−−−−−−−−−−−√

Top Surface Area of a Triangular Prism Formula

Finds the area contained by the triangular surface at the top of the prism. This is the same area as the bottom surface area.

Atop=14(a+b+c)(b+c−a)×(c+a−b)(a+b−c)−−−−−−−−−−−−−−−−−−−−−−−√

Bottom Surface Area of a Triangular Prism Formula

Finds the area contained by the triangular surface at the bottom of the prism. This is the same area as the top surface area.

Abot=14(a+b+c)(b+c−a)×(c+a−b)(a+b−c)−−−−−−−−−−−−−−−−−−−−−−−√

Lateral Surface Area of a Triangular Prism Formula

Finds the total area contained by the three rectangular sides of the prism. You can think of the lateral surface area as the total surface area of the prism minus the two triangular areas at the top and bottom of the prism.

Alat=h(a+b+c)

Total Surface Area of a Triangular Prism Formula

Finds the total area of all sides of a triangular prism. Total surface area of a prism includes the area of the top and bottom triangle sides of the prism, plus the area of all 3 rectangular sides.

Atot=Atop+Abot+Alat

Step-by-step explanation:

Height of a Triangular Prism Formula in Terms of Volume

Finds the height of a triangular prism by solving the Volume Formula for height. Height, h, is calculated from volume, V, and side lengths a, b and c.

h=4V÷[(c+a−b)(a+b−c)−−−−−−−−−−−−−−−−−√×(a+b+c)(b+c−a)−−−−−−−−−−−−−−−−−√]

Height of a Triangular Prism Formula in Terms of Lateral Surface Area

Finds the height of a triangular prism by solving the Lateral Surface Area Formula for height. Height, h, is calculated from lateral surface area, Alat, and side lengths a, b and c.

h=Alat(a+b+c)

The surface area of this figure will be 540 square feet.

Surface area refers to the area of an open surface or the border of a multi-object, whereas the area of a plane region or plane field refers to the area of a form or planar material.

A complex solid made out of triangular and rectangular prisms. The triangular prism is centered on the rectangular prism's top.

The surface area of the shape is given as,

SA = 2(15 x 8 + 8 x 5) + 15 x 5 + 11 x 5 + 9 x 5 + 9 x 5

Tell me if you don't understand!

The division of the expression when 40 divided by 28 is [tex]\dfrac{10}{7}[/tex] or  1.42857143.

A number that divides another number without leaving any remainder and the quotient is a whole number is called a factor.

The factors of 12 are = 1,2,3,4,6 and 12.

Here, when these factor will divide 12, there will no remainder, i.e. they will completely divide 12.

The division of the expression 40 divided by 28 is calculated as:

The factors of 40 are : 1,2,4,5,8,10,20 and 40

The factors of 28 are: 1,2,4,7,14 and 28.

This expression can be written as:

[tex]\dfrac{40}{28}=\dfrac{1\times2\times4\times5\times8\times10\times20\times40}{ 1\times 2\times 4\times 7\times 14\times 28}[/tex]

The numbers cancel out using the rule of divisibility, and the remaining  fraction will be [tex]\dfrac{10}{7}[/tex] and in decimal form will be 1.42857143.

Thus, when 40  is divided by 28, the result is 1.42857143 or [tex]\dfrac{10}{7}[/tex] in fraction form.
