Step-by-step explanation:

The graph of x - y = 1 is plotted below

Plotting linear graphs

The 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

The graph of the equation y = x - 1 is plotted below

how do i graph x+4y=8​

Answers

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

Answers

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

Step-by-step explanation:

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.

In a MBS first year class, there are three sections each including 20 students. In the first section, there are 10 boys and 10 girls, in the second section there are 15 boys and 5 girls, and in the third section, there are 12 boys and 8 girls. Five students are selected at random from each group to form committee of 15 students. What is the probability that all the 15 students selected are girls?​

Answers

Answer:

[tex]3.52 \times 10^{-9} = 3.52 \times 10^{-7}\%[/tex] probability that all the 15 students selected are girls

Step-by-step explanation:

The selection is from a sample without replacement, so we use the hypergeometric distribution to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

All girls from the first group:

20 students, so [tex]N = 20[/tex]

10 girls, so [tex]k = 10[/tex]

5 students will be selected, so [tex]n = 5[/tex]

We want all of them to be girls, so we find P(X = 5).

[tex]P_1 = P(X = 5) = h(5,20,5,10) = \frac{C_{10,5}*C_{10,5}}{C_{20,5}} = 0.0163[/tex]

All girls from the second group:

20 students, so [tex]N = 20[/tex]

5 girls, so [tex]k = 5[/tex]

5 students will be selected, so [tex]n = 5[/tex]

We want all of them to be girls, so we find P(X = 5).

[tex]P_2 = P(X = 5) = h(5,20,5,5) = \frac{C_{5,5}*C_{15,5}}{C_{20,5}} = 0.00006[/tex]

All girls from the third group:

20 students, so [tex]N = 20[/tex]

8 girls, so [tex]k = 8[/tex]

5 students will be selected, so [tex]n = 5[/tex]

We want all of them to be girls, so we find P(X = 5).

[tex]P_3 = P(X = 5) = h(5,20,5,8) = \frac{C_{8,5}*C_{12,5}}{C_{20,5}} = 0.0036[/tex]

All 15 students are girls:

Groups are independent, so we multiply the probabilities:

[tex]P = P_1*P_2*P_3 = 0.0163*0.00006*0.0036 = 3.52 \times 10^{-9}[/tex]

[tex]3.52 \times 10^{-9} = 3.52 \times 10^{-7}\%[/tex] probability that all the 15 students selected are girls

A right triangle has one leg that is 4 more than twice the other. The area of the triangle is 35. Find the length of the sides.

Answers

Answer:

one leg = 5

other leg = 14

Step-by-step explanation:

let 'x' = length of shorter leg

let '2x + 4' = length of longer leg

A = 1/2bh

35 = 1/2x · 2x + 4

35 = x² + 4

x² + 4 - 35 = 0

(x + 7)(x - 5) = 0

x = -7 and x = 5

We can eliminate -7 as an answer since a length cannot be negative

Answer:

The shorter leg = 5

The longer leg = 14

The hypotenuse = 14.866.....

Step-by-step explanation:

if we represent the smaller leg as "x" we firstly represent the longer leg as...

Longer leg = 2x + 4

(We can do this based on the question)

Now we need to undersstadn t in a right angle triangle the legs can be used as a height and base. So we can make the following equation.

[tex]A_{triangle} = \frac{bh}{2}[/tex]

Substitute the lengths of the legs as based and height and get...

[tex]A_{triangle} = \frac{(2x + 4)(x)}{2}[/tex]

[tex]35 = \frac{2x^{2} + 4x}{2}[/tex]

[tex]35 = x^{2} + 2x[/tex]

[tex]35 = x(x + 2)[/tex]

From here we can see that x = 5.

Therefore the lengths are as follows...

The shorter leg = x = 5

The longer leg = 2(5) + 4 = 14

The hypotenuse = [tex]\sqrt{5^{2} + 14^{2} }[/tex]

The hypotenuse = [tex]\sqrt{5^{2} +14^{2} }[/tex]

The hypotenuse = 14.866.....

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

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
