Solve the system of equations by substitution.
3x+2y=10 y=3x-4
x= y=​

Answers

Answer:

x=2;  y=2

Step-by-step explanation:

3x+2y=10

y=3x-4

We can substitute y from the first equation with the second equation:

3x+2(3x-4)=10

3x+6x-8=10

9x=18

x=2

Now plug this in to any of the equations (i used second equation):

y=3(2)-4

y=6-4

y=2

Check your answers:

y=3x-4

2=3(2)-4

2=6-4

2=2

4x + 3 = x + 2(x + 7)
step by step

Answers

Answer:

x=11

Step-by-step explanation:

4x + 3 = x+ 2x + 14

4x + 3 = 3 x + 14

4x - 3x = 14 -3

x= 14 - 3

x= 11

Answer:

x=11

Step-by-step explanation:

Distribute :

4x + 3 = x + 2( x+ 7)

4x + 3 = x + 2x + 14

Combine like terms :

4x + 3 = x + 2x + 14

4x + 3 = 3 x+ 14

Subtract 3 from both sides of the equation :

4x + 3 = 3x + 14

4x + 3-3 = 3x + 14 -3

Simplify :

what ever way you know how to subtract the numbers you should get this answer :

4x = 3x + 11

Subtract 3 from both sides of the equation :

4x = 3x + 11

4x - 3x = 3x + 11 - 3x

Simplify :

combine like terms

multiply by 1

combine like terms

x= 11

Answer:

  1. adjacent: ACB, BCD and BCD, DCE. vertical: ACB, DCE and BCD, ECA

  2. adjacent: KGJ, JGI and HGM, MGK. vertical: JGI, MGL and HGM, KGJ

  3. adjacent. x = 49°

  4. adjacent. x = 71°

Step-by-step explanation:

As I noted in the attachment, vertical angles are formed from opposite rays (lines that cross). They share only a vertex. Each of the crossing lines makes up one side of each of the vertical angles. (You can think of each line as being made of opposite rays from the vertex of the angle.)

Adjacent angles share both a vertex and one side. (They do not overlap.) For example, in Figure 2, angles KGM and LGM are not adjacent, even though they share verex G and side GM. This is because they overlap. In that figure, angles KGL and LGM are adjacent angles.

__

1. To identify adjacent angles, choose a ray and make note of the angles on either side of it.

  adjacent: {ACE, ACB}, or {BCA, BCD}, or {DCB, DCE}, or {ECD, ECA}

To identify vertical angles, choose two crossing lines and one of the 4 spaces between them. The other vertical angle will be non-adjacent, in the opposite space of the same size.

  vertical: {ACB, ECD}, or {ACE, BCD}

__

2. adjacent: any of the pairs {KGJ, JGI}, {JGI, IGH}, {IGH, HGM}, {HGM, MGL}, {MGL, LGK}, {LGK, KGJ}.

Note that these are the nearest, smallest pairs of adjacent angles. This is usually what we are talking about when we refer to adjacent angles. We could add to the list pairs like {IGH, IGK}, {IGM, IGL}.

 vertical: (lines IL, HK) {IGH, LGK} or {IGK, LGH}; (lines IL, MJ) {IGM, LGJ} or {IGJ, MGL}; (lines HK, MJ) {HGM, KGJ} or {HGJ, KGM}

__

3. The angles share a ray, so are adjacent. Together, they make up a right angle, so they are complementary.

  x = 90° -41°

  x = 49°

__

4. The angle share a ray, so are adjacent. Together, they make up a linear angle, so are supplementary.

  x = 180° -109°

  x = 71°

I need help find this in slope intercept form

Answers

Answer:

y=2x+24 is you're answer

Answer:

I'm pretty sure it's y=2x+24

Step-by-step explanation:

The slope intercept formula is y=mx+b. So to get the equation into that form you would have to get y by itslef, which  means you would have to subtract 8x from both side. And then you can't have a number in front of the y so you have to divide by that for all of the terms.This then gives you your answer.

An arithmetic sequence is represented by the explicit formula A(n) = 2 +(n − 1)(− 5)
What is the recursive formula?

Answers

Answer:

a+(n-1)d please do you get it or

Answer:

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 5

Step-by-step explanation:

Given the explicit formula

A(n) = 2 - 5(n - 1)

Compare with the standard form

A(n) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = - 5

A recursive formula allows a term in the sequence to be found by adding d to the previous term.

Then recursive formula is

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 5 , with a₁ = 2

Emily says she can prove the Pythagorean Theorem using the following diagram. She explains that she can divide the squares on the two shorter sides into grids with equal-sized grid squares. She says she can then rearrange the grid squares to cover the area of the square on the hypotenuse, which proves that the sum of the squares on the two shorter sides equals the square on the hypotenuse. A 3 by 3 square, a 4 by 4 square, and a 5 by 5 square, put together to form a right triangle with legs 3 and 4 and hypotenuse 5. Is this a valid geometrical proof that a2 + b2 = c2 for all right triangles? Yes, because there are 9 grid squares on one side, 16 grid squares on the other side, and 25 grid squares on the hypotenuse, and 9 + 16 = 25. Yes, because it shows that you can rearrange the squares on the shorter sides to fill up the area of the square on the larger side. No, because a proof needs to have equations in order to be valid. No, because this proof only works when you can draw grids on the squares. It does not work for all right triangles. A student wrote the equation 620 = 124n.
