Answers

Answer: y = (1/7) x - 2

Step-by-step explanation:

The slope-intercept form of an equation is y = mx + b, where m is the slope and b is the y-intercept.

The slope of an equation is the change in y over the change in x.

We can see from the image that every time the line increases by 1 in the rise (y), it increases by 7 in the run (x).

Therefore, the slope is 1/7.

The y-intercept of a line is the point at which it intercepts the y-axis.

From the image, we can see that it intersects at the point (0,-2)

Therefore, the slope-intercept form is y = (1/7) x - 2

Take two points

(0,-2)(-7,-3)

Slope:-

[tex]\\ \sf\longmapsto \dfrac{-1}{-7}=\dfrac{1}{7}=m[/tex]

Using a geometric sequence, it is found that the missing terms of the table are, respectively, given by:

[tex]243, 1, \frac{1}{81}[/tex]

What is a geometric sequence?

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

[tex]a_n = a_1q^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

From the table, we get that the common ratio is of [tex]q = \frac{1}{3}[/tex], hence each term is the previous divided by 3, or the next multiplied by 3. Hence, the missing terms are given by:

[tex]3 \times 81 = 243[/tex]

[tex]3 \times \frac{1}{3} = 1[/tex]

[tex]\frac{1}{27} \times \frac{1}{3} = \frac{1}{81}[/tex]

what is an equation of the line that passes through the point (5, -7) and has a slope of 0

Answers

Answer:

y=-7

Step-by-step explanation:

Simple enough. Slope of zero means that x does not have to be determined. So if you just put the y coordinate in a slope of zero, you should get your answer.

The equation of line is y = -7.

Equation of line is,

                        [tex]y=mx+c[/tex]

Where m is slope.

Given that, slope is 0.

Equation of line become, [tex]y=0*x+c=c[/tex]

This equates to:

There is no denominator a^-7

The power is positive 1/a^7

Step-by-step explanation:

Remark

We are not told what the restrictions on the power are. Here are the possibilities.

There is no denominator.The power must be positive.

So I will give the answer to both conditions. You will have to choose.

There is no denominator

That means that The powers are subtracted

Multiply numerator and denominator by a+6

a^- 13 * a^6

=========

a^-6 * a^6

To start a^(-6 + 6) = a^0 which = 1. That is not written, so you are left with a^ (-13 + 6) = a ^ -7

The answer must have a positive power.

Multiply the numerator and denominator by a^13.

numerator

a^-13 * a^13

a^(-13 + 13)

a^0

1

So we are left with 1 in the numerator.

a^-6 * a^13

a^(-6 + 13)

a^7

Answer: what is left is  1/a^7

A biased sample is best described by:

C. The sample does not accurately represent the population.

What is sampling?

It is a common statistics practice, when we want to study something from a population, we find a sample, which is a group of members of this population. The sample has to be representative of the population, that is, it has to involve all of it's groups. If it does not involve all the groups, it is not an accurate representation of the population, and is called biased, hence option C is correct.

Step-by-step explanation:

The ozone layer helps to sustain terrestrial life by absorbing incoming UV radiation.

We have,

UV radiation can cause damage to living organisms, such as skin cancer, cataracts, and other health problems.

The ozone layer absorbs much of this radiation, preventing it from reaching the Earth's surface and thus helping to sustain terrestrial life.

Option B is incorrect because the ozone layer is located in the stratosphere, above the troposphere.

Option C is incorrect because while the ozone layer can play a role in maintaining the Earth's temperature, its primary function is to absorb UV radiation.

Option D is incorrect.
