By a small online search, i found that the actual question seems to be:

"Stephanie uses a ride service to get to different places in her city. If Stephanie uses Uber the service charges $5.00 plus 1.50 per mile . If Stephanie uses lift the service charges $2.00 per mile. Let m represent the number of miles traveled. Which of the following statements are true . Select all that apply"

The statements are not provided, so i will answer it in a general way.

We have two different equations:

1) a fixed amount of $5.00 plus $1.50 for each mile, m.

This is a linear equation:

y1 = $1.50*m + $5.00

2) No fixed amount, only $2.00 for each mile, m.

y2 = $2.00*m

Now, the things we can see are which service will be cheaper as a function of m.

To see this, we can see the difference between y1 and y2.

When the difference is negative, this means that y1 is cheaper.

When the difference is positive this means that y2 is cheaper.

When the difference is zero, both services charge the same.

D = y1 - y2 = $1.50*m + $5.00 - $2.00*m

                 = (-$0.50)*m + $5.00

First let's find when it is zero.

              0 =  (-$0.50)*m + $5.00

            5.00/0.5 = m = 10

So for 10 miles, both services charge the same.

As the coefficient that multipies m is negative, if we have m > 10, then the difference will be negative.

This means that for m > 10, y1 is cheaper.

Then for m < 10, y2 is cheaper.

Answer:

y=1.08x-2144.24

Step-by-step explanation:

find the slope: m=(19.00-13.60)/(2003-1998)=1.08

so we have y=1.08x +b

next, use the point (2003, 19.00) to find b:

19.00=1.08*2003 +b =>b=-2144.24

There is no requirement in the question. I'll calculate the area of the rectangle to help you with this question.

Answer:

[tex]A=15\ cm^2[/tex]

Step-by-step explanation:

System of Equations

Let's call y to the length of a rectangle, x to its width. There are two conditions that will help us to solve for x and y.

[tex]y=3x-4[/tex]

[tex]2x+2y=16[/tex]

Divide by 2:

[tex]x+y=8[/tex]

To solve the system, we'll substitute the y in the first equation into the second:

[tex]x+3x-4=8[/tex]

Joining like terms:

[tex]4x=8+4[/tex]

Solving:

[tex]x=12/4=3[/tex]

Find the value of y:

[tex]y=3x-4=3*3-4=9-4=5[/tex]

Thus, the length of the rectangle is 5 cm and its width is 3 cm. The area is calculated as:

[tex]A=xy=3\ cm\cdot 5\ cm=15\ cm^2[/tex]

[tex]\boxed{A=15\ cm^2}[/tex]

Answer:

4

Step-by-step explanation:

Answer:

4 2/11

Step-by-step explanation:

The absolute value is the distance between a number and zero. This means that absolute value cannot be negative because you cannot travel a negative distance. The distance between - 4 2/11 is 4 2/11.

Hope This Helps :)

The absolute value of -4(2/11) is 46/11.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

-4(2/11)

= -46/11

Now,

The absolute value.

= |-46/11|

= 46/11

Thus,

The value is 46/11.

Answer:

8.25÷53790 is 0.00015337423 and the other one is 0.00015337423

1. The solution of the expression '' 8.25 divided by 53790 '' will be 0.00015337423.

2. The solution of the expression '' 825 divided by 5379000 '' will be 0.00015337423.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The mathematical expression are;

1. 8.25 divided by 53790

2. 825 divided by 5379000

Now,

After divide we get;

1. 8.25 divided by 53790 = 8.25 ÷ 53790

8.25 ÷ 53790 = 8.35 / 53790

                     = 835 / 5379000

After divide we get;

= 0.00015337423

Thus, 8.25 ÷ 53790 = 0.00015337423

2. The expression is;

825 divided by 5379000 = 825 ÷ 5379000

                                        = 825 / 5379000

                                        = 0.00015337423

Thus, 825 ÷ 5379000 = 0.00015337423

So, Both the expression have same solution.

Therefore,

1. The solution of the expression '' 8.25 divided by 53790 '' will be 0.00015337423.

2. The solution of the expression '' 825 divided by 5379000 '' will be 0.00015337423.

Answer:

The present age of Dave is 40 years

Step-by-step explanation:

Let the present age of Johns be x

We are given that Dave is six years less then twice Johns  age.

Dave's present age = 2x-6

We are also given that The sum of John and Dave's ages is 63.

So, [tex]x+2x-6=63[/tex]

[tex]3x-6=63[/tex]

[tex]3x=63+6[/tex]

[tex]3x=69[/tex]

[tex]x=\frac{69}{3}[/tex]

[tex]x=23[/tex]

Dave's present age = 2x-6=2(23)-6=40

Hence The present age of Dave is 40 years

To trisect a 60-degree angle you first construct an equilateral triangle.

Option C is the correct answer.

The angles between two lines are the angles formed by two intersecting lines, measured in degrees or radians.

Several different types of angles can be formed between two lines, including acute angles, right angles, and obtuse angles.

We have,

To trisect a 60-degree angle, we can use the fact that an equilateral triangle has three 60-degree angles.

The steps to trisect a 60-degree angle using an equilateral triangle are as follows:

Draw an equilateral triangle with one of its vertices at the angle to be trisected.

Draw a line from the vertex of the angle to the opposite side of the triangle, dividing the angle into two 30-degree angles.

Draw a line from the vertex of the angle to the point where the opposite side intersects the circle centered at the vertex with a radius equal to the length of one side of the equilateral triangle. This will divide one of the 30-degree angles into two 15-degree angles.

Draw a line parallel to the opposite side of the triangle from the point where the 15-degree angle is divided to the adjacent side of the triangle. This will trisect the 60-degree angle into three 20-degree angles.

Thus,

By constructing an equilateral triangle, we can trisect a 60-degree angle.

Find the y-intercept and x-intercept

1) Find the x-intercept, substitute y = 0

0 = -x-5

5=-x

x= -5

Therefore, the x-intercept is at -5

2) Find the y-intercept, substitute x = 0

y= -0 - 5

y = 0 - 5

y = -5

Therefore, the y-intercept is at -5 too.

Plot the line graph from x = -5 to y = -5 and it should be like this.

Note - You can easily find the y-intercept just looking at "b value" from y = mx+b when m is the slope and b is the y-intercept.

Answer:

Step-by-step explanation:

1) since -5 is graphed in the equation we know the y-intercept is -5

2) since we already know the point (0,-5) form the y-intercept, we pick x-values and plug them into the equation. I'll use -4, 3, and 9

y=-x-5      y=-x-5     y=-x-5

y=-9-5      y=-3-5    y=--4-5

y=-14        y=-8        y=-1

3) we then plot the 4 points we found and draw a straight line connecting them, and then we put arrows on either side of the line because the question did not say that it was a line segment.

0 F x>o v 0 cover the interval (-4,-3

The statement which is true about the graphed function is that F(x) > 0 over the interval (-∞, -4).

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given is a graph of a function.

The options contains the open interval (-∞, -3) and (-∞, -4).

It is clear that along this interval, the graph is situated above the X axis.

This means that the values of y is all greater than 0.

At x = -4, F(x) = 0

For all x < -4, F(x) > 0

So the correct statement is F(x) > 0 over the interval (-∞, -4).

Hence F(x) > 0 over the interval (-∞, -4).
