please answer with an explanation
50 points given with explanation

Answers

Answer 1

Step-by-step explanation:

♤ 3(b-5) = 27

=> 3b - 15 = 27

=> 3b = 27 + 15 = 42

=> b = 42/3

=> b = 14 (Ans)

♤ 2x/3 = 6

=> 2x = 6 × 3 = 18

=> x = 18/2

=> x = 9 (Ans)

♤ 2(n + 5) = 15

=> 2n + 10 = 15

=> 2n = 15 - 10 = 5

=> n = 5/2

=> n = 2.5 (Ans)

♤ a + a + a + a = 24

=> 4a = 24

=> a = 24/4

=> a = 6 (Ans)

♤ 4c + 6 = 18

=> 4c = 18 - 6 = 12

=> c = 12/4

=> c = 3 (Ans)

y = (x − 4)2 − 4
y = (x + 4)2 − 4
y = (x + 2)2 + 6
y = (x + 2)2 + 12

Answers

Answer:

Hi there!

The vertex form equation is y=a(x-d)^2+c where the vertex is (d, c).

The vertex is always the turning point when the y-values start to travel in the opposite direction from which they began traveling on the opposite side of the turning point. Therefore the point (4, -4) is the vertex.  

y=a(x-4)^2-4

We can sub in a point on the graph in order to solve for the a-value. Let's use (6, 0), and sub that in for x and y.

0=a(6-4)^2-4

0=a(2)^2-4

4=4a

a=4/4

a=1

Therefore the equation is y=(x-4)^2-4

38=1/8k+47
Find the value of k

Answers

Answer:

[tex]k=-72[/tex]

Step-by-step explanation:

[tex]38=\frac{1}{8} k+47[/tex]

Switching the sides of the equation isn't required, but it helps to reduce confusion.

[tex]\frac{1}{8}k+47=38[/tex]

Since there is a positive 7, we are going to do the opposite operation, which is addition.

[tex]\frac{1}{8}k+47-47=38\\\text\:\:\:\:\:\:-47\:\:\:\:\:\:\:\:\:-47[/tex]

Simplify

+47 - 47 will cancel each other out, so we are left with:

[tex]\frac{1}{8}k=-9[/tex]

Now, multiply 8 to both sides, since the equation gives us 1 divided 8, so the opposite operation of division is multiplication.

[tex]8\cdot \frac{1}{8}k=8\left(-9\right)[/tex]

On the right side, we have the same thing as [tex]\frac{8}{1} \cdot \frac{1}{8}[/tex], so 8 we can cancel the equation on the right side since they are both the same number.

On the left, we have [tex]8\left(-9\right)[/tex], which is -72.

Therefore, [tex]k=-72[/tex].

Read a paragraph from an essay supporting Trumans decision to use the atomic bomb against Japan during World War II.[1] Many people have argued that nothing could justify the presidents use of the atomic bomb because it killed so many innocent civilians. [2] Truman himself refused to drop a third atomic bomb on Japan because he was horrified by the death and devastation it had caused. [3] However, he never regretted his decision to use it in the first place. [4] Using the bomb brought an immediate end to a war that might have gone on for months or even years longer. [5] It is impossible to put a number on how many more deaths the continuing war might have caused, but there are indications. [6] Millions had already died in the Pacific theater. [7] Whenever US troops invaded an island, they knew the fight was to the death.
