PLEASE HELP 3x - (2x - 17)-2/3 (12x – 9)

Answer:

y = 2x + 1

Step-by-step explanation:

Slope formula is y2-y1/x2-x1

-5-3/-3-1

-8/-4

2

Thus, the slope is 2 (m = 2)

Find the y intercept.

y = 2x + b

3 = 2(1) + b

3 = 2 + b

1 = b

y = 2x + 1

Answer:

Quadrants I and II.

O: (-2, 2)

N: (-2, 4)

M: (1, 4)

P: (1, 2)

Step-by-step explanation:

When rotating about the origin 90 degrees in a counterclockwise direction, focus on the coordinates of one point on the preimage at a time. So, the x-coordinate on the image will be the opposite of the y-coordinate of the preimage, and the y coordinate of the image will be the x-coordinate of the preimage. That sounds complicated so here is an example from the problem.

O is a point on the preimage. Its coordinates are (2, 2). To find the x-coordinate, take the opposite of the image's y-coordinate. The y-coordinate is 2, so it will be a -2 x-coordinate on the image. To find the y-coordinate on the image, take the x-coordinate of the preimage (O). The x-coordinate of O is 2, so the y-coordinate of the image will be 2. Combine those together and after a 90 degree counterclockwise rotation, you get a point of (-2, 2)

Step-by-step explanation:

Rectangles

The sides of the rectangular fields are 500 meters and 700 meters. The diagonal of the rectangle can be calculated as the hypotenuse of the right triangle formed by the two sides, thus:

[tex]d=\sqrt{x^2+y^2}[/tex]

Where x and y are the lengths of the sides. For the rectangular field, we have:

[tex]d=\sqrt{500^2+700^2}=\sqrt{250000+490000}=\sqrt{740000}=860.23\ m[/tex]

The angle between the diagonal and the longest side can be calculated using trigonometry. Please refer to the image attached.

[tex]\displaystyle \cos\theta=\frac{x}{d}=\frac{700}{869.23}=0.8137[/tex]

Answer:

Step-by-step explanation:Coordinate geometry is one of the most important and exciting ideas of mathematics. In particular it is central to the mathematics students meet at school. It provides a connection between algebra and geometry through graphs of lines and curves. This enables geometric problems to be solved algebraically and provides geometric insights into algebra.

The invention of calculus was an extremely important development in mathematics that enabled mathematicians and physicists to model the real world in ways that was previously impossible. It brought together nearly all of algebra and geometry using the coordinate plane. The invention of calculus depended on the development of coordinate geometry.

Answer:

x = 1

Step-by-step explanation:

first you distribute :  3(x + 1) -> 3x  -2(x - 1) -> -2x + 2

next you combine like terms : 2 + 6 = 8

3x + 3 = -2x + 8

subtract 3 from both sides : 3x = -2x + 5

add 2x to both sides : 5x = 5

divide both sides by 5 and you get :  x = 1

Answer:

Step-by-step explanation:

Starting with <EDG=43

You need to find <CDF. AB is a straight line, making it 180.

ADC=90 and FDB=20

180-90-20 to get CDF

70=CDF 70 doesnt equal 43

CDF and EDG are not congruent.

Find EDA. GC=180 ADC= 90 EDG=45

180-90-45

45

you can also see that ADC and EDG are adjacent angles and if you look, GDA makes up a right angle which is 90 so you could subtract the 45 from that to get 45 as well.

ADB=180

45+133=178

no

We already figured out that CDF=70

70+20=90 so yes.

BDG is obviously a right angle but looks can be deceiving so math wise

AEG is 90 and AB is 180

180-90=90

so BDG is 90

20+90+43=180

155=180

no

Answer:

9.0×10^3K/moles

Step-by-step explanation:

ionization energy of these electrons = Energy of photons - kinetic energy of the electrons

Given

Kinetic energy of electron = 1.34×10^5

Energy of photons = 1.43 x 105 kJ/mole

Required

Ionization energy of these electrons

Ionization energy of these electrons = 1.43×10^5-1.34×10^5

ionization energy of these electrons = 0.09×10^5 kJ/mol

= 9.0 × 10^3 kJ/mol

Hence the ionization energy of these electrons is 9.0×10^3K/moles

The solution is Option D.

The x-intercept is ( -3 , 0 ), and the y-intercept is ( 0 , 12 )

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of the line be f ( x ) = y

And , the equation is

f ( x ) = 4x + 12

So , y = 4x + 12

To find the x intercept of the line ,

Substitute the value of y = 0

So , 0 = 4x + 12

Subtracting 12 on both sides , we get

4x = -12

Divide by 4 on both sides , we get

x = -3

Therefore , the x-intercept is ( -3 , 0 )

Now , To find the y intercept of the line ,

Substitute the value of x = 0

So , y = 12

Therefore , the y-intercept is ( 0 , 12 )

Hence , The x-intercept is ( -3 , 0 ), and the y-intercept is ( 0 , 12 )

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

We know that the volume of a cylinder is given by the formula:

[tex]V=\pi r^2h[/tex]

And we want to find the expression that represents the volume when the radius is (x+8) and the height is (2x+3).

So, let's substitute (x+8) for r and (2x+3) for h. This yields:

[tex]V=\pi (x+8)^2(2x+3)[/tex]

Let's expand.

Expand the square term first. We can use the perfect square trinomial pattern, which is:

[tex](a+b)^2=a^2+2ab+b^2[/tex]

Here, our a is x and b is 8. So:

[tex]V=\pi (x^2+2(x)(8)+(8)^2)(2x+3)[/tex]

Simplify:

[tex]V=\pi (x^2+16x+64)(2x+3)[/tex]

Expand further. This time, we will use the distribute property. So:

[tex]V=\pi ((x^2+16x+64)(2x)+(x^2+16x+64)(3))[/tex]

Multiply:

[tex]V=\pi((2x^3+32x^2+128x)+(3x^2+48x+192))[/tex]

Combine like terms:

[tex]V=\pi((2x^3)+(32x^2+3x^2)+(128x+48x)+(192))[/tex]

Add:

[tex]V=\pi(2x^3+35x^2+176x+192)[/tex]

Distribute the π:

[tex]V=2\pi x^3+35\pi x^2+176\pi x+192\pi[/tex]

So, our answer is C.

And we're done!

Answer:

C

Step-by-step explanation:

V=πr²h

V=π(x^2+64)h

V=π(x^2+64)(2x+3)
