I Have To Repost This Because I Was Giving Wrong Answers. The Instructions Are To Complete Each Proof

Answers

Answer 1

Answer and Step-by-step explanation:

We are given:

[tex]\frac{2y-1}{-3} = 5[/tex]

First, we multiply both sides by -3.

2y - 1 = 15

Now we add 1 to both sides.

2y = 16

Finally, we divide by 2 to each side.

y = 8

We are given:

2x + 30 = -4(5x -2)

First we distribute the -4 to 5x and -2.

2x + 30 = -20x + 8

Now we subtract 8 from both sides.

2x + 22 = -20x

Now we subtract 2x from both sides.

22 = -22x

Finally, we divide by -22 to both sides.

-1 = x

  Statements:                             Reasons:

             Given

  2y - 1 = 15                Multiplication Property of Equality

  2y = 16                       Addition like terms

  y = 8                                         Division Property of Equality

  Statements:                             Reasons:

2x + 30 = -4(5x -2)    Given

  2x + 30 = -20x + 8                Distribution Property of Equality

  2x + 22 = -20x           Subtraction Property of Equality

  22 = -22x                                 Subtraction Property of Equality

  -1 = x                                         Division Property of Equality

4x + 4y = 12
-2x + y = -3

Answers

Answer:

(9/4, 3/4)

Explanation:

4x + 4y = 12
2(-2x + y = -3)

4x + 4y = 12
-4x + 4y = -6

8y = 6

y = 3/4


4x + 4(3/4) = 12

4x + 3 = 12

4x = 9

x = 9/4

What is the Constant of a Linear Graph?

The constant of a linear graph, is the slope of the line = change in y / change in x.

Using any of the two points on the line, (2, 5) and (4, 10):

Constant/slope = (10 - 5)/(4 - 2)

Constant/slope = (5)/(2)

Constant/slope = 2.5

The constant is: B. 2.5.

how do you solve these kinds of equations? (3x+5) (3x+5)

Answers

Answer:

-5/3

Step-by-step explanation:

(3x+5)(3x+5) is the factored form of the quadratic: 9x^2+30x+25

In equation form, it will be 9x^2+30x+25 = 0 so we have:

(3x+5)(3x+5) = 0

To solve these types of equations, we find the roots. Since the product of these numbers is 0, (3x+5) has to be equal to 0.

3x + 5 = 0

Subtract 5

3x = -5

Divide by 3

STU is an equilateral triangle. If ST is one less than twice x, SU is 37 less than five times x, and TU is 11 more than x, find x and the measure of each side.

Answers

Answer:

x = 12Side = 23 units

Step-by-step explanation:

STU is an equilateral triangle. And:

ST = 2x - 1SU = 5x - 37TU = x + 11

All sides are equal. Then take one pair and solve for x:

2x - 1 = 5x - 373x = 36x = 12

Substitute x to find the side length:

2x - 1 = 5x - 37 = x + 11 = 23

After the Civil War, the era known as Reconstruction began. During this era, the federal government tried to grant rights to former slaves and rebuild the South. There was progress, including the passage of the 13th, 14th and 15th Amendments, granting freedom, citizenship and voting rights to former slaves.In the 1877 presidential election, both the Republican and Democratic candidates claimed to have won. Rutherford B. Hayes, the Republican candidate, became president in exchange for withdrawing federal troops from the South. The lack of military presence meant there was no longer a way to enforce the new amendments or punish those who treated African Americans unfairly. Reconstruction came to an abrupt end. Not only that, much of the progress made in the 12 years of Reconstruction was reversed as Jim Crow laws took hold. When we look at the end of Reconstruction and the rise of Jim Crow, it is important to remember that history did not have to be this way. Reconstruction efforts could have continued if the country had committed to it. What explanation do you have for which of these events occurred during the Reconstruction era? A. The Civil War began.B. Rutherford B. Hayes became president.C. Progress toward racial equality in the South was reversed.D. Three amendments were passed to grant rights to former slaves.GIVING 20 AND BRAINLIST Work out the volume of this prism. *HELP**URGENT*DUE TONIGHT* Please help with this I am giving brainliest!
