how do i graph x+4y=8
Answer:
x = 8 y = 2
(8,2)
Step-by-step explanation:
You have to find the value of both x and y
x + 4y = 8
to find x you have to cancel out y so,
x + 4(0) = 8
x = 8
to find y you have to cancel out x
0 + 4y = 8
4y = 8
divide both sides by 4
y = 2
Hope this Helps!!!
By changing the equation to slope intercept form we draw the graph and graph is given in attachment.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Let us convert the equation of line x+4y=8 to slope intercept form.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
x+4y=8
4y=8-x
Divide both sides by 4
y=-x+2
Now let us find few point to draw the graph.
If x=0
y=2
If x=1
y=1
If x=2
then y=0
if x=3
then y=-1
Now plot (0, 2), (1, 1) and (3, -1) and draw the graph
Hence, by plotting the points (0, 2), (1, 1) and (3, -1) we draw the graph and the graph is in attachment.

Solve the following equation.
4x - 2 = 22-8x
Answer:
x = 2
Step-by-step explanation:
4x - 2 = 22 - 8x
Move all variables to a single side by adding 8x to both sides of the equation.
4x + 8x - 2 = 22 - 8x + 8x
12x - 2 = 22
Add 2 to both sides to move the constants to one side.
12x - 2 + 2 = 22 + 2
12x = 24
Divide both sides by 12 to isolate the x.
12x / 12 = 24 / 12
x = 2
Answer:
x = 2
Step-by-step explanation:
Add 2 to both sides.
4x - 2 +2 = 22 - 8x + 2
Simplify.
4x=-8+24
Add 8x to both sides.
4x+8x= -8x + 24 + 8x
Simplify.
12x = 24
Divide both sides by 12.
12x/12 = 24/12
Simplfy.
x = 2

The graph of x - y = 1 is plotted below
Plotting linear graphsThe given equation is:
x - y = 1
The equation can be rewritten as:
y = x - 1
This is of the form y = mx + 1
where m is the slope
c is the y-intercept
Compare the equation y = mx + 1 with y = x - 1
The slope, m = 1
The y-intercept, c = -1

Answer:
x = 13.5
Step-by-step explanation:
x = 11 · (sin 34°) / sin 27°
Answer:
120
Step-by-step explanation:
180-27-34=119
119 round up to nearest 10 = 120
You look up at 1 but you are not soposed to answer the question by looking at 1, if you have nearest 10 to round then always look at the units.
Always look at the second digit of the nearest number that you would round up.
Example:
round 560 to the nearest 100.
The answer would be 600 because 0-4 goes down and 5-9 goes up,
and in this number 5 goes up so the answer would be rounded up.
If the question said round 560 to the nearest 10 then the answer would be the same because the second digit is 0 and 0 goes down so it does not make any difference. If the second digit goes down then you do not need to change your answer the answer would be the same as the question number.

Step-by-step explanation:
We can let the [tex]?[/tex] be [tex]x[/tex]. Rewriting the proportion, we get:
[tex]\frac{50}{2000}=\frac{6}{x}[/tex]
Solving for [tex]x[/tex], we get:

[tex]50*x=2000*6[/tex] (Cross-Products Property)
[tex]50x=12000[/tex] (Simplify)
[tex]\frac{50x}{50}=\frac{12000}{50}[/tex] (Divide both sides of the equation by [tex]50[/tex] to get rid of [tex]x[/tex]'s coefficient)
[tex]x=240[/tex] (Simplify)
Since [tex]?=x[/tex], we know that [tex]?=240[/tex]. Hope this helps!

Answer:
$9 and $12
Step-by-step explanation:
Let "s" be small boxes and "L" be large boxes.
12*s + 6*L = $180
3*s + 2*L = $51
From the first equation:
L = ($180 - 12*s) / 6 = $30 - 2*s
Plug that into 2nd equation:
3*s + 2*($30 - 2*s) = 3*s + $60 - 4*s = $51
s = $9
L = $30 - 2*s = $30 - $18
L = $12

936
1,008
1,080
The volume of the rectangular prism is V = 936 cm³
What is the Volume of a Rectangle?The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle
Volume of Rectangle = Length x Width x Height
Volume of Rectangle = Area of Rectangle x Height
Given data ,
To find the volume of the figure, we need to calculate the volumes of the two rectangular prisms separately and then add them together.
The volume of a rectangular prism is given by the formula:
Volume = length x width x height
For the first prism:
Length = 12 centimeters
Width = 9 centimeters
Height = 2 centimeters
Volume of first prism = 12 cm x 9 cm x 2 cm = 216 centimeters³
For the second prism:
Length = 10 centimeters
Width = 9 centimeters
Height = 8 centimeters
Volume of second prism = 10 cm x 9 cm x 8 cm = 720 centimeters³
Now, we add the volumes of the two prisms together to get the total volume of the figure:
216 cubic centimeters + 720 cubic centimeters = 936 centimeters³
Hence , the rectangular prism has volume of 936 cm³

Answer:
x = -3
Step-by-step explanation:
The solution to the equation ...
f(x) = g(x)
is the x-value where the functions have equal values. That is the x-coordinate of the point where the graphs intersect. The intersection point is (-3, 5), so the solution to the equation is x = -3.

Se necesitan cortar 3 cintas de 40 cm, 50 cm y 60 cm, en trozos igua-
les de manera que todas sean iguales y con la mayor longitud posible.
¿Cuántos trozos se cortarán?
Answer:
Se cortarán en 15 trozos.
Step-by-step explanation:
Para determinar la longitud de cada trozo tal que todos los trozos tengan la misma longitud, se descompone factorialmente cada número:
[tex]40 = 2\times 2 \times 2 \times 5[/tex]
[tex]50 = 2\times 5\times 5[/tex]
[tex]60 = 2\times 2\times 3\times 5[/tex]
Ahora, determinamos el factor común de los tres números. Se puede encontrar que los tres números comparten un 2 y un 5. Entonces, el factor común es:
[tex]r = 2\times 5 = 10[/tex]
Este factor común representa la longitud de cada segmento. La cantidad de elementos se obtiene al dividir la suma de longitudes de las cintas por el factor común:
[tex]x = \frac{40\,cm+50\,cm+60\,cm}{10\,cm}[/tex]
[tex]x = \frac{150\,cm}{10\,cm}[/tex]
[tex]x = 15[/tex]
Se cortarán en 15 trozos.
