The graph that correctly represents f(x) = –2(x + 4)² is graph (B).

So, graph of: f(x) = –2(x + 4)²

Then,

Now, plot (-2x - 8)² on the graph.

(Refer to the graph attached below)

Therefore, the graph that correctly represents f(x) = –2(x + 4)² is graph (B).

Answer:

-1 = 11

0 = 13

1 = 15

2 = 17

5 = 23

Step-by-step explanation:

2 (-1) +13 = 11

2 (0) +13 = 13

2 (1) +13 = 15

2 (2) +13 = 17

2 (5) +13 = 23

Answer:

g = 6

Step-by-step explanation:

5.2g + 10 = 2.2g + 28 (Given)

3g + 10 = 28 (Subtracted 2.2g on both sides)

3g = 18 (Subtracted 10 on both sides)

g = 6 (Divided 3 on both sides)

To check to make sure you are correct, simply substitute your answer for g:

5.2(6) + 10 = 2.2(6) + 28

31.2 + 10 = 13.2 + 28

41.2 = 41.2

You'll know you're correct if they both equal the same. In this case, the solution works.

Answer:

A. -5(x + 2) = -4x - 12 - x + 2

Step-by-step explanation:

The equation that has infinitely many solutions will be the same on both sides.

A is the correct answer.

Simplify the equation by distributing -5 and adding like terms:

-5(x + 2) = -4x - 12 - x + 2

-5x - 10 = -4x - 12 - x + 2

-5x - 10 = -5x - 10

So, this equation is the same on both sides and will have infinitely many solutions.

A is the correct answer.

Answer:

A has infinitely many solutions

Step-by-step explanation:

Once you distribute A you get

-5x-10= -4x-12-x+2

Once you simplfy all that you get

-5x-10= -5x-10

You can check this by putting in a random number and both sides will be equal.

Answer: k=8

Step-by-step explanation: So your equation is 7+k/4=9. Remember, the goal of this problem is to isolate the k. The first thing you should do is subtract 7 from both sides. You should get k/4=2. Then, multiply both sides by 4 to isolate the k. You should get k=8. Hope this helps!

x=5 and n=36

Step-by-step explanation:

For the first question: 32/8 = 4/1

4/1 = 20/x

4x = 20

x = 5

For the second question: 63/81 = 21/27

21/27 = 28/x

21x = 756

x = 36

Step-by-step explanation:

So what you need to do is is how fast they traveled every ten miles once you do that take how fast they traveled every ten miles and multiply it by 9.

So it seems to me that 1 day for most people they walked 10 miles. So if it takes 7 days for them to get there you need to do 90 divided by 7 which will get you your answer.

I hope this helped you understand better!

Answer:  11 3/7 miles per day, and it will take them 7.875 days to go 90 miles

Answer:

did you find the answer ??

The required height of the wall where the ladder meets the wall is 12 m.

Given that,
A ladder that has a length of 13 m leans against a wall with the base of the ladder 5 m away from the bottom of the wall. Use this information to find how high above the ground the ladder meets the wall is to be determined.

In a right-angled triangle, its side, such as hypotenuse, perpendicular and base is Pythagorean triplets.

Here,
Let the height be h,
Applying Pythagoras' theorem,
h = √[13²-5²]
h = √169-25
h = √144
h = 12

Thus, the required height of the wall where the ladder meets the wall is 12 m.

Answer: C

Step-by-step explanation:

The missing side of the triangle is the hypotenuse. We are given the length for both legs. To find the midding leg, we need to use teh Pythagorean Theorem.

Pythagorean Theorem: a²+b²=c²

A and b are the legs, while c is the hypotenuse. We plug in the legs and solve for c.

2²+3.6²=c²           [exponent]

4+12.96=c²          [add]

16.96=c²              [square root both sides]

[tex]c=\sqrt{16.96}[/tex]

Now that we have found the hypotenuse, we know the answer is C.

Hello!

[tex]\large\boxed{\sqrt{16.96}cm}[/tex]

Use the Pythagorean theorem to solve for the missing side of the triangle:

a² + b² = c²

Plug in the given side lengths to solve for "c", or the Hypotenuse:

(2)² + (3.6)² = c²

4 + 12.96 = c²

16.96 = c²

Take the square root of both sides:

√16.96 = c

Here, [tex]$ \hat p$[/tex] = sample proportion of red outcomes

[tex]$ \hat p =\frac{58}{100}$[/tex]

[tex]$ \hat p$[/tex] = 0.58

So we have to test,

[tex]$H_0 : p = 0.5$[/tex]

V/S    [tex]$H_a: p \neq 0.5 $[/tex]

The test statistic is

[tex]$z = \frac{\hat p - p}{\sqrt{\frac{p(1-p)}{n}}}$[/tex]

[tex]$z = \frac{0.58 - 0.5}{\sqrt{\frac{0.5(1-0.5)}{100}}}$[/tex]

  [tex]$=\frac{0.08}{0.05}$[/tex]

  = 1.600

P value using the z table is 0.110

So P value greater than 0.05
