Answer:

12x+40

Step-by-step explanation:

(3/5x+2)*20=

12x+40

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.

4) And check your work by going to Google and typing "student desmos graphing calculator" and typing in your equation.

Step-by-step explanation:

Answer:

The function is Speed, f(t) = x/t

Step-by-step explanation:

The given information are;

The distance the man drove = 40 miles

The duration of time the man drove = 2-hours

Given that a function maps each item of the input domain to a single item of the output domain, we can have the following relation for the above parameters;

Speed = (Distance travelled)/(Time taken)

Where, speed f(t), is a function of the time taken, t, to travel a distance x

The function is therefore;

Speed, s = f(t) = x/t

Speed = 40/2 = 20 mile per hour.

Answer:

The function is Speed, f(t) = x/t

Step-by-step explanation:

Answer:

o

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).

Answer:

No

Step-by-step explanation:

Given that:

Amount earned when a student does comminty service = $5

Number of students in club = 12

Amount earned E, is a function of number of members (n) who does community service.

Hence,

E = n * amount earned per member

Is 24 a possible output?

To test, then E = 24

24 = n * 5

24 = 5n

24/5 = 5n/5

4.8 = 5

Hence, 24 is not a possible output, be use number of membwra cannot be a decimal

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:

D

Step-by-step explanation:

Given

17 ≤ - 3x + 2 ≤ 26 ( subtract 2 from each of the 3 intervals )

15 ≤ - 3x ≤ 24

Divide the 3 intervals by - 3, reversing the symbols as a result of dividing by a negative quantity.

- 5 ≥ x ≥ - 8 , that is

- 8 ≤ x ≤ - 5 → D

[tex]17 \leqslant - 3x + 2 \leqslant 26[/tex]

Subtract sides -2

[tex]17 - 2 \leqslant - 3x + 2 - 2 \leqslant 26 - 2 \\ [/tex]

[tex]15 \leqslant - 3x \leqslant 24[/tex]

Divided sides by -3

=======================================

Point :

When the sides of a inequality multiply or divided by an negative number It changes direction and returns them.

=======================================

Thus ;

[tex] \frac{15}{ - 3} \geqslant \frac{ - 3}{ - 3}x \geqslant \frac{24}{ - 3} \\ [/tex]

[tex] - 5 \geqslant x \geqslant - 8[/tex]

[tex] - 8 \leqslant x \leqslant - 5[/tex]

Thus the correct answer is (( D )) .

Answer:

1km per minute

Step-by-step explanation:

Given the table in the picture :

The average rate of change over the interval from 8 to 15 minutes will be :

Change in distance / change in time

Change in distance between 8 and 15 minutes :

Distance d1 at 8 minutes t1 = 7km

Distance d2 at 15 minutes t2 = 14km

Average rate of change = (d2 - d1) / (t2 - t1)

Average rate of change = (14 - 7)km / (15 - 8)min

Average rate of change = 7km / 7minutes

Average rate of change = 1km per minute

Answer:

The rate of change is 1 kilometer per minute

Step-by-step explanation:

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.

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.
