#1 Line

Slope = 4.000/2.000 = 2.000

x-intercept = 1/-2 = -0.50000

y-intercept = 1/1 = 1.00000

#2 Slope = 2.000/2.000 = 1.000

x-intercept = 2/-1 = -2.00000

y-intercept = 2/1 = 2.00000

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

Equation of a Straight Line

1.1 Solve y-2x-1 = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-2x-1 = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 1/1 so this line "cuts" the y axis at y= 1.00000

y-intercept = 1/1 = 1.00000

Calculate the X-Intercept :

When y = 0 the value of x is 1/-2 Our line therefore "cuts" the x axis at x=-0.50000

x-intercept = 1/-2 = -0.50000

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.000 and for x=2.000, the value of y is 5.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 5.000 - 1.000 = 4.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = 4.000/2.000 = 2.000

Geometric figure: Straight Line

Slope = 4.000/2.000 = 2.000

x-intercept = 1/-2 = -0.50000

y-intercept = 1/1 = 1.00000

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

y-(x+2)=0

Answers

Answer:

Step-by-step explanation:

There are 500 respondents will you be able receive for the money paid.

What is mean by expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The budgeted for a company to complete guest satisfaction surveys for you is, $4,800.

And, They charge $1,800 + $6 per respondent.

Now,

Let Number of respondents will you be able receive for the money paid is, x

Hence, We can formulate;

⇒ $1800 + $6x = $4800

⇒ 1800 + 6x = 4800

⇒ 6x = 4800 - 1800

⇒ 6x = 3000

⇒ x = 500

Thus, There are 500 respondents will you be able receive for the money paid.

In the expression 3x - 4y + z, what is the
coefficient of z?

Answers

Answer:

1

Step-by-step explanation:

The coefficient is the number in front of a variable. There is a hidden coefficient of 1 in front of z. The reason it is not shown is because any number multiplied by 1 is just that number so showing the 1 is redundant.

The coefficient  of z in the expression 3x- 4y +z is 1.

What is expression?

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.

Given:

3x - 4y + z

As, we know a coefficient is a number that is multiplied by a variable.

So, the coefficient of x is 3, coefficient of y is 4 and coefficient  of z is 1.

For every 1 litre of water used 150ml of sucrose and 600ml of saline solution is used

Answers

Question:

For every 1 litre of water used to make a medicine, 600 ml of sucrose and 150ml of saline solution are used.

Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.

Answer:

[tex]Water : Sucrose : Saline = 20 : 3 : 12[/tex]

Step-by-step explanation:

Given

[tex]Water = 1L[/tex]

[tex]Sucrose = 150mL[/tex]

[tex]Saline= 600mL[/tex]

Required

Express as a ratio to the simplest form

First convert the volume of water to mL

[tex]Water = 1L[/tex]

[tex]Water = 1 * 1000mL[/tex]

[tex]Water = 1000mL[/tex]

Express as ratio:

[tex]Water : Sucrose : Saline = 1000mL : 150mL : 600mL[/tex]

[tex]Water : Sucrose : Saline = 1000 : 150 : 600[/tex]

Divide through by 10

[tex]Water : Sucrose : Saline = 100 : 15 : 60[/tex]

Divide through by 5

[tex]Water : Sucrose : Saline = 20 : 3 : 12[/tex]

Plot two lines by clicking the graph.
Click a line to delete it.



HELP ASAP

Answers

Answer: The solution is (2, 2)

Step-by-step explanation:

We have the system of equations:

y = 2*x - 2

x + y = 4

The first step is to write both equations as linear equations in the slope-intercept form.

y = 2*x - 2

y = -x + 4

Now we have two lines, and we can just graph them, the easiest way is the replace the value of x and obtain two points that belong to the line, and then draw a line that passes through both lines.

For example with the first one, we can firt replace x by 0 to get:

y = 2*0 - 2

y = -2

Then the point (0, -2) belongs to this line.

Now we can replace x by 1 to get:

y = 2*1 - 2 = 0

y = 0

The point (1, 0) belongs to this line.

Then we can draw these two points in the graph, and just draw a line that passes through these two points.

Once you have your two lines drawn, the solution of the system will be the point in which the lines intersect.

Below, you can see the two lines graphed (the green is the first one and the red is the second one)

And we can see that they intersect in the point (2, 2)

Then the solution of the system is (2, 2)
