The y-intercept of the equation y = (x - 4) is -4

From the question, we have the following equation that can be used in our computation:

y --(x - 4)

Rewrite the equation properly

So, we have the following representation

y = (x - 4)

To calculate the y-intercept, we set x to 0

So, we have the following representation

y = 0 - 4

Evaluate the difference

y = -4

Hence, the y-intercept is -4

The simple interest that Oliver needs to pay is $ 90

Simple interest is nothing but interest on a loan at a rate. The formula for Simple interest is given below

Simple interest, I = ptr

where p = principal amount

t = time period in years

r = rate of interest in decimals

Here we have

Oliver borrowed $1,500 to purchase a riding lawn mower  

The rate of interest r = 12%

=> 12/100 = 0.12 (in decimals )

The time period given = 6 months = 0.5 years   [ 6/12 = 0.5 ]  

From the above formula,

The simple interest, I = ptr

=> I = $1,500(0.12) (0.5) = $ 90

Therefore,

The simple interest that Oliver needs to pay is $ 90

Answer:

(∞,-3) and (1,-∞)

Step-by-step explanation:

Decreasing means going down or in math terms, going toward the negatives.

When you are talking intervals in math, you only want to use the x-axis for the interval points. We write the interval as if it was a coordinate point though.

Looking at the graph it looks like it is going from infinity to -3 or written as (∞,3) and from 1 to negative infinity or written as (1, -∞)

The interval(s) for which the function shown below is decreasing are (∞,-3) and (1,-∞).

A function is a relationship between two sets of values in mathematics where each input value (or "argument") corresponds to a certain output value.

In most cases, the input values come from a set referred to as the function's domain, while the output values come from a set referred to as the function's range.

Declining is the mathematical phrase for decreasing or moving towards the negatives.

Mathematicians only use the x-axis to represent interval points when discussing intervals. Yet, we express the interval as if it were a coordinate point.

If you look at the graph, it appears to be traveling from infinity to -3, which is written as (,3), and from one to negative infinity, which is written as (1, -).

The slope of the line x = 3 is undefined

How to describe the slope of the line

The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.

Mathematically, the slope is the change in y divided by the change in x. That is:

Slope = y2-y1 / x2-x1

Let's pick any two convenient points on the line:

(3, 9) and (3, -9) = > x1 = 3, y1 = -9 and  x2 = 3, y2 = 9

Slope = 9-(-9) / 3-3  = 18/0

The denominator here is 0, if you evaluate this using a calculator you will a maths error. So we say the slope is undefined

Notice that: There is no change in x i.e. x1 = x2

Therefore, the slope of x = 3 is undefined because x = 3 is a vertical line

An equation modeling the population, p, of Ohio given the year, t is,

p = 0.04t + 10.98.

What is population?

The term "population" refers to all citizens who are either permanently residing in a country or who are just passing through. This indicator reveals how many people typically reside in a certain area. Growth rates are the population changes that occur each year as a result of births, deaths, and net migration.

Given: In the year 2000, the population of Ohio was 11.03 million people. By the year 2017 the population of Ohio was 11.66 million people.

From this we get, two points (0, 11.03) and (17, 11.66).

First to find the slope using the above two points.

[tex]m=\frac{11.66 - 11.03}{17-0} = \frac{0.63}{17} = 0.04[/tex]

Now to find the equation,

Consider,

p - 11.66 = 0.04(t - 17)

p - 11.66 = 0.04t - 0.68

          p = 0.04t - 0.68 + 11.66

          p = 0.04t + 10.98

Therefore, the equation modeling the population, p, of Ohio given the year, t is, p = 0.04t + 10.98

Answer: f^-1(x)= - 1/5x - 4/5

Step-by-step explanation:

substitute y for f(x):              y= -5x-4

interchange x and y:            x=-5y-4

swap the sides:                     -5y-4=x

move the constant                -5y=x+4

divide both sides by 5          y= - 1/5x - 4/5

substitute f^-1(x) for y          f^-1(x)= - 1/5x - 4/5

The graph that beast describes the slope of -2/3 passing through points (-1, 0) is in option c

Information given in the question include

a linear function graph

The data is plotted as a linear function

A linear function consists of functions where the variables has exponents of 1. The graph of linear functions is a straight line graph and the relationship is expressed in the form.

y = mx + c

The slope is represented as m, The slope by definition is the ratio change of the output values to the input values

the slope, m = -2/3

negative slopes slants from top left to bottom right as in a and c

from the graph, option c has points (-1, 0) and (0, -2/3)

m = (-2/3 - 0) / (0 - -1)

m = (-2/3) / (0 + 1)

m = -2/3

If price p(x) =26(4)^{-x/5}, the revenue when 15 units are sold is equal to $6.09.

From the information provided, the amount of revenue with respect to price that's being generated in this scenario can be calculated by using the following function (expression):

R(x) = x × P(x)

Where:

Since the revenue function, we would simply substitute the value of the unit price and evaluate as follows:

Revenue, R(x) = x × 26(4)^{-x/5}

Substituting the given parameters into the formula, we have;

Revenue, R(x) = 15 × 26(4)^{-15/5}

Revenue, R(x) = 15 × 26(4)^{-3} or (15 × 26)/4³

Revenue, R(x) = 15 × 26(0.015625) or 390/64

Given:

A business started the year with a net worth of $4,873. During the first six months of the year, the business recovered and increased its net worth to a value of $15,866.

Six months net worth = 15,866 - 4873

The slope of the line that is parallel to the line -7x-5y=-6 is -7/5

It is possible to determine a line's direction and steepness by looking at its slope. Finding the slope of lines in a coordinate plane can aid in anticipating whether the lines are parallel, perpendicular, or none at all without actually using a compass.

Any two unique places along the line may be used to determine the slope of any line. When two different places on a line are considered, the slope of a line formula compares the vertical change to the horizontal change in each case. We shall comprehend how to discover the slope in this piece, along with some of its uses.

Given, line is -7x-5y=-6

We have to write the given line in slope-intercept form

Then, y= (-7/5)x+(6/5)

The slope-intercept form is y= mx +c

By using the slope-intercept form,

Slope=(-7/5)

The lines that are parallel to y= (-7/5)x+(6/5) have the same slope of -7/5

Therefore, the slope of the line that is parallel to the line -7x-5y=-6 is -7/5
