Which equation represents a line which is perpendicular to the line x – 2y = -14?

Answers

Answer:

any equation that have the slope of -2

A line which is perpendicular to the line x – 2y = -14 will have a slope of -2

What is a slope?

The slope of a line is a measure of its steepness.

Given an equation of a line  x – 2y = -14

We know that, the slope of a line perpendicular to another line will have a slope of its negative reciprocal.

Therefore, slope of the line perpendicular to the line x – 2y = -14  will be -2

Hence, equation of the line perpendicular to the line x – 2y = -14 will have a slope of -2

Using either substitution or elimination method, solve the system of equations that consists of 8x+y= -16 and -3x+y=-5 Your solution will be a coordinate of integers. ​

Answers

Answer:

x= -1

y= -8

Step-by-step explanation:

Solve for y in 8x + y = -16

y = -16 - 8x

Substitute y = -16 - 8x into -3x + y = -5

-11x - 16 = -5

Solve for x in -11x - 16 = -5

x = -1

Substitute x = -1 into y = -16 - 8x

y = -8

Therefore,

x= -1

y= -8

Answer:

(-1, -8)

Step-by-step explanation:

SUBSTITUTION METHOD:

8x + y = -16-3x + y = -5

Solve for y in the first equation by subtracting 8x from both sides.

y = -16 - 8x

Substitute this value for y into the second equation.

-3x + (-16 - 8x) = -5

Remove the parentheses and simplify.

-3x - 16 - 8x = -5

Combine like terms.

-11x - 16 = -5

Add 16 both sides of the equation.

-11x = 11

Divide both sides of the equation by -11.

x = -1

Substitute this value for x into either equation (I'm using the first equation).

8(-1) + y = -16

Multiply and simplify.

-8 + y = -16

Add 8 to both sides of the equation.

y = -8

ELIMINATION METHOD:

8x + y = -16-3x + y = -5  

Subtract the second equation from the first equation to "cancel" the y-variable.

11x = -11

Divide both sides of the equation by 11.

x = -1

Substitute this value for x into either equation (I'm using the second equation).

-3(-1) + y = -5

Multiply and simplify.

3 + y = -5

Subtract 3 from both sides of the equation.

y = -8

The solution to this system of equations is (-1, -8).

The points (11, 13) and (7, 13) fall on a particular line. What is its equation in slope-intercept form?

Answers

Answer:

slope -intercept form y=mx+c

The equation of the straight line

                                 y = 0x +13

Step-by-step explanation:

Step(i):-

Given that the points

           (11 ,13) and (7,13)

The slope of the line

    [tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{13-13}{7-11} = \frac{0}{-4} =0[/tex]

Step(ii):-

Equation of the straight line passing through the point (11,13) and slope m=0

y - y₁ = m( x-x₁)

y - 13 =0(x-11)

y-13 =0

y =13

slope -intercept form y=mx+c

y = 0x +13

given a population mean of 27.1 with a standard deviation of 8.4 and a sample size of 10, answer these questions.
part A: what is the standard deviation of the sampling distribution of x hat? show your work.
PartB: what does the sample size need to be if you want the standard deviation of the sampling distribution of x hat to be 2.8? show your work.

Answers

Answer:

a) 2.66

b) 9

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

part A: what is the standard deviation of the sampling distribution of x hat? show your work.

We have that [tex]\sigma = 8.4, n = 10[/tex]. So

[tex]s = \frac{\sigma}{\sqrt{n}} = \frac{8.4}{\sqrt{10}} = 2.66[/tex]

PartB: what does the sample size need to be if you want the standard deviation of the sampling distribution of x hat to be 2.8?

This is n when [tex]s = 2.8[/tex]. So

[tex]s = \frac{\sigma}{\sqrt{n}}[/tex]

[tex]2.8 = \frac{8.4}{\sqrt{n}}[/tex]

[tex]2.8\sqrt{n} = 8.4[/tex]

[tex]\sqrt{n} = \frac{8.4}{2.8}[/tex]

[tex]\sqrt{n} = 3[/tex]

[tex](\sqrt{n})^2 = 3^2[/tex]

[tex]n = 9[/tex]

The first platform of the Eiffel Tower is 2,280 inches above the ground. The second platform is 376 feet above the ground. How many yards separate the first platform from the second platform?​

Answers

Answer:

62.0496 yards separate the first platform from the second platform

Step-by-step explanation:

We have to make the conversion of both units to yards.

Each feet has 12 inches.

Each inch is 0.0278 yards.

The first platform of the Eiffel Tower is 2,280 inches above the ground.

So

2280*0.0278 = 63.384 yards above the ground.

The second platform is 376 feet above the ground.

So

376*12*0.0278 = 125.4336 yards above the ground

How many yards separate the first platform from the second platform?​

125.4336 - 63.384 = 62.0496

62.0496 yards separate the first platform from the second platform

Unlike the graph of function f, the graph of function g decreases as x increases.The graph of both functions have a vertical asymptote of x = 0.

What is a function?

A function in mathematics simply means the relation between a set of inputs and a set of permissible outputs.

In this case, the graph of both functions have a vertical asymptote of x = 0. This is because the divisor equals to zero for a value of x.
