Need Help... Fast! Will Give Brainiest What Is The Solution Set Of X/4 &lt; 9/x ?

Answers

Answer 1

Answer:

Option (4)

Step-by-step explanation:

Given inequality is,

[tex]\frac{x}{4}\leq \frac{9}{x}[/tex]

[tex]\frac{x}{4}-\frac{9}{x}\leq 0[/tex]

[tex]\frac{x^{2}-36}{4x}\leq 0[/tex]

x ≥ 0 [For x = 0, fraction is not defined]

(x - 6)(x + 6) ≤ 0

x - 6 ≤ 0

x ≤ 6

Or

x + 6 ≤ 0

x ≤ -6

Therefore, solution set is (-∞, -6] ∪ (0, 6]

By plotting the solution area on a number line,

Option (4) will be the answer.

What is an equation of the line that passes through the points (-4, 8) and
(2, -1)?

Answers

Answer:

Kayla,  learn this,  :D  more math is based on it.  Just learn it, just memorize the following

Step-by-step explanation:

m = slope

m = rise / run

m = y2 - y1   /  x2 - x1       ( this is still rise over run but in point form )

they give us two points to plug into the above formula

P1 = (-4, 8 )  in the form of ( x1, y 1 )

P2 = (2, -1)  in the form of (x2, y2 )

now plug those into the above formula

m = ( -1 - 8 ) / ( 2-(-4) )

m = -9  /  ( 2 + 4 )

m = -9 / 6

m = - 3/2

since we know the slope now  , we can use the point slope equation of

y - y1 = m ( x - x1)

use the m we found and either point  , P1 or P2

y - 8 = -3/2(x -(-4) )

y-8 = -3/2(x + 4)

y-8 = -3/2x - 6

y = -3/2x -6 + 8

y = -3/2x + 2

there you go  :)

David used exactly 8 cups of flour to make 6 loaves of bread. How many loaves of bread can he make with 12 cups of flour?

Answers

ANSWER: David can make 9 loaves of bread.

EXPLANATION: Half of 8 = 4, half of 6 = 3

8 + 4 = 12 cups of flour, 6 + 3 = 9 loaves of bread.

David can make 9 loaves of bread with 12 cups of flour.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

David used exactly 8 cups of flour to make 6 loaves of bread.

SO, Half of 8 = 4, half of 6 = 3

8 + 4 = 12 cups of flour,

6 + 3 = 9 loaves of bread.

Thus, David can make 9 loaves of bread with 12 cups of flour.

Data from a representative sample were used to estimate that 31% of all computer users in a recent year had tried to get on a Wi-Fi network that was not their own in order to save money. You decide to conduct a survey to estimate this proportion for the current year. What is the required sample size if you want to estimate this proportion with a margin of error of 0.05

Answers

Answer:

The required sample size is 329.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

31% of all computer users in a recent year had tried to get on a Wi-Fi network that was not their own in order to save money.

This means that [tex]\pi = 0.31[/tex]

Confidence level is not given, so we assume 95%.

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

What is the required sample size if you want to estimate this proportion with a margin of error of 0.05?

We need a sample size of n. n is found when M = 0.05. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.05 = 1.96\sqrt{\frac{0.31*0.69}{n}}[/tex]

[tex]0.05\sqrt{n} = 1.96\sqrt{0.31*0.69}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.31*0.69}}{0.05}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.31*0.69}}{0.05})^2[/tex]

[tex]n = 328.6[/tex]

Rounding up

The required sample size is 329.

Juan saved x dollers last month. This month he saved $8 more than 3 times the amount he saved last month. he saved a total of $141 how much did he save last month. Write an equation and solve. ​

Answers

Answer:

he save last month $33.25

Step-by-step explanation:

Let us assume last month saving be x

This month saving be 3x + $8

And, the total would be $141

So based on the above information

The equation is

x + 3x + $8 = $141

4x + $8 = $141

4x = $141 = $8

4x = $133

x = $33.25

Hence, he save last month $33.25

Therefore the same is relevant

Darryl has 2/3 of a bag of dog food. His dog eats 4/9 of a bag per week. How many weeks will the dog food last?

Answers

it should last him 1/3

A fraction is a part of a whole and it can be expressed as a quotient, in which the numerator is divided by the denominator.

The number of weeks the dog will take to finish 2/3 of a bag of dog food is 1 (1/2) weeks.

What is a fraction?

A fraction is a part of a whole and it can be expressed as a quotient, in which the numerator is divided by the denominator.

We have,

The amount of dog food in the bag = 2/3

The amount of dog food the dog eats per week = 4/9

We need to find the number of weeks that the dog finishes 2/3 of dog food.

The number of weeks:

1 week = 4/9 dog food

Multiply both sides by (9/4 x 2/3)

(9/4 x 2/3) x 1 week = (9/4 x 2/3) x 9/4 dog food

3/2 weeks = 2/3 dog food

[ 3/2 = 1 (1/2) ]

1(1/2) weeks = 2/3 dog food

This means in one and a half weeks the dog finished 2/3 of dog food.

Thus the number of weeks the dog will take to finish 2/3 of a bag of dog food is 1 (1/2) weeks.

Two sides of a right triangle are 8 and 12. Find the missing side of 8 and 12 are a leg and a hypotenuse.​

Answers

Answer:

8.94 if no rounding is necessary.

Step-by-step explanation:

Pythagorean Theorem. What we know is only one leg and the hypotenuse, sooo...

8² + b² = 12²

64 + b² = 144

Subtract 64 from both sides...

64 - 64 + b² = 144 - 64

b² = 80

[tex]\sqrt{80}[/tex] = 8.94 if you're not rounding.

what are the coordinates of B', the image of point B, after dilation by a scale factor of 1.5 centered at (5, -5)​

Answers

Answer:

B' = (7.5, -7.5)

Step-by-step explanation:

Given the coordinate B = (x, y)

If the coordinate is dilated by factor of k, the resulting coordinate will be (kx, ky)

For the coordinate (5, -5), if dilated by a factor of 1.5, the required coordinate will be;

B'= (1.5(5), 1.5(-5))

B' = (7.5, -7.5)

This gives the required coordinate

3) not tangent

Step-by-step explanation:

If they are tangent, the triangles formed will be right triangles.

Check using the Pythagorean theorem:

1) 18² = 14.4² + 11.7²

324 = 207.36 + 136.89

324 ≠344.25       not tangent  

2) 7.5² = 4.5² + 6²

56.25 = 20.25 + 36

56.25 = 56.25     tangent
