The probability that the fraction will be greater than 5/6

Answer:

The given equation is NOT linear.

Step-by-step explanation:

5x^4+5y = 9

The given equation is NOT linear.

Reason:

A linear equation is defined as the equation for the straight line, where the degree of variables involved is always equal to 1.

But in the given equation :

Degree if x = 4

and degree of y = 1

As degree of x≠ 1 so, the given equation is not linear,

[tex]\bf \begin{cases} -7x+8y=1\\ 4x-8y=20 \end{cases}\qquad \qquad \stackrel{\textit{using elimination}}{ \begin{array}{llll} -7x~~\begin{matrix} +8y \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~=1\\ ~~4x~~\begin{matrix} -8y \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~=20\\ \cline{1-1}\\ -3x~\hfill =21 \end{array}}[/tex]

[tex]\bf x=\cfrac{21}{-3}\implies \blacktriangleright x=-7 \blacktriangleleft \\\\\\ \stackrel{\textit{substituting in the 2nd equation}}{4(-7)-8y=20}\implies -28-8y=20\implies -8y=48 \\\\\\ y=\cfrac{48}{-8}\implies \blacktriangleright y = -6 \blacktriangleleft[/tex]

The solution to the system is (x, y) = (-2.2, -1.8) the y-coordinate of the solution is -1, the correct option is A.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that;

The equations;

–7x + 8y = 1

4x – 8y = 20

Now,

To solve this system of equations, we can use the elimination method. We can multiply the first equation by 2 and add it to the second equation to eliminate y:

-14x + 16y = 2 +4x - 8y = 20

-10x = 22

x = -2.2

Now that we have x, we can substitute it into either equation to solve for y. Let’s use the first equation:

-7x + 8y = 1 -7(-2.2) + 8y = 1 15.4 + 8y = 1 8y = -14.4 y = -1.8

Therefore, the solution to the system of equations will be (x, y) = (-2.2, -1.8) the y-coordinate will be -1.

Answer:

y = - [tex]\frac{1}{2}[/tex] x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line

m = [tex]\frac{0-2}{4-0}[/tex] = [tex]\frac{-2}{4}[/tex] = - [tex]\frac{1}{2}[/tex]

The line crosses the y- axis at (0, 2) ⇒ c = 2

y = - [tex]\frac{1}{2}[/tex] x + 2 ← equation of line

Answer:

x + 2y = 4

Step-by-step explanation:

The y intercept (where it crosses the y axis) is (0,2)

Another point on the line is (4,0)

We can find the slope from these two points

m = (y2-y1)/(x2-x1)

   = (0-2)/(4-0)

   =-2/4 = -1/2

We have the slope and the y intercept

y = mx+b  where m is the slope and b is the y intercept

y = -1/2x +2

We want the equation of the line in standard form

Ax +By =C

Add -1/2x to each side

1/2x +y =  -1/2x +1/2x +2

1/2x +y =   2

Multiply by 2 because we do not want fractions

2(1/2x +y) = 2* 2

x + 2y = 4

Answer:

75

Step-by-step explanation:

Geometric means you should think common ratio (words like multiplication or division).

First term=3

Second term=15

What can you multiply to first to give you second term? Please say 5! Yes 5! Why? Because 3*5=15.

So 5 is called the common ratio.  5 is the number that you will multiply to a term to find the very next term.

So the third term would be 15*5=75

The next value in the geometric sequence is 75.

A geometric sequence is a sequence of numbers in which each term can be found by multiplying the previous term by a fixed, non-zero number called the common ratio. In this case, to find the next value in the sequence, we need to determine the common ratio. We can divide the second term (15) by the first term (3) to find the common ratio:

Common ratio = 15/3 = 5

Now that we know the common ratio is 5, we can find the third term in the sequence:

Third term = Second term × Common ratio = 15 × 5 = 75

{x|x<3 or x > 1}

Option B is correct.

Final answer:

To solve the equation (3x-9)+x+(x+28)=184, you combine like terms to get 5x + 19 = 184, subtract 19 from both sides to get 5x = 165, and then divide both sides by 5 to find that x = 33.

Explanation:

To solve the equation (3x-9)+x+(x+28)=184, we begin by combining like terms. This involves adding together the x terms and combining the constant numbers. The x terms (3x, x, and x) add up to 5x, and the constants (-9 and +28) add up to 19. Therefore, the equation simplifies to 5x + 19 = 184.

Next, we isolate the variable x. We do this by subtracting 19 from both sides of the equation, getting 5x = 165. Then, we divide both sides by 5 to find x. Dividing 165 by 5, we find that x = 33.

Thus, the solution to the equation is x = 33.

A) The Length Of Diagonal PS And Diagonal P'S' Are In The Ratio 1:3

Step-by-step explanation:

when a polygon is multiplied or scaled by k, a constant scalar number to form another polygon then these two polygons are similar. And similar polygons have proportional lengths of corresponding sides. Ratios within the polygons sides will be equal to the corresponding sides ratios of the other polygons.  The corresponding sides of image are scalar multiple of preimage

x'=kx

where x' is side in image

x is side in preimage

and k is scalar number

so the ratio between these two corresponding side will be 1:3

In given case as the scalar factor k is 3 so the ratio between corresponding sides will be 1:3.

Hence option A is correct:The Length Of Diagonal PS And Diagonal P'S' Are In The Ratio 1:3!

A statement about polygon PQRST and its image after dilation, polygon P'Q'R'S'T', that is correct include the following: A) The Length Of Diagonal PS And Diagonal P'S' Are In The Ratio 1:3.

In Mathematics and Geometry, the formula for calculating the scale factor of any geometric object or figure is represented by the following:

Scale factor = side length of image/side length of pre-image

Based on the graph, the length of diagonal P'S' is 5 units while the length of diagonal PS is 15 units. In this context, the length of segment A'B' can be calculated as follows;

Scale factor = P'S'/PS

Scale factor = 5/15

Scale factor = 1/3 ⇒ Ratio = 1 : 3.

In conclusion, we can logically deduce that the length of diagonal PS and diagonal P'S' are in the ratio 1 : 3, which implies that diagonal PS is three times as long as diagonal P'S'.

Part 3) The final value of a painting after its initial value m, increases by 2/5 -----> [tex]\frac{7}{5}m[/tex]

Part 4) The total number of markers that Nancy has if she gives away 2/5 of her m markers to Amy ----->  [tex]\frac{3}{5}m[/tex]

Step-by-step explanation:

Part 1) The price of a USB memory, stick selling at a 21% discount of its market price (m)

we know that

100% is the market price m

100%-21%=79%

79%=79/100=0.79

so

The price of a USB memory with a 21% discount of its market price is equal to multiply m by 0.79

(0.79)*m=0.79m

Part 2) The price or a CD that sells for 21% more than the amount (m) needed to manufacture the CD

we know that

100% is the amount m

100%+21%=121%

121%=121/100=1.21

so

The price or a CD that sells for 21% more than the amount (m) is equal to multiply m by 1.21

(1.21)*(m)=1.21m

Part 3) The final value of a painting after its initial value m, increases by 2/5

we know that

100% is the initial value m

2/5=0.40=40%

100%+40%=140%

140%=140/100=1.4

Convert to fraction

1.4=14/10=7/5

so

The final value is equal to m multiplied by 7/5  

[tex]\frac{7}{5}m[/tex]

Part 4) The total number of markers that Nancy has if she gives away 2/5 of her m markers to Amy

we know that

100% is the number of makers m

2/5=0.40=40%

100%-40%=60%

60%=60/100=0.6

Convert to fraction

0.6=6/10=3/5

The total number of markers that Nancy has is equal to multiply m by 3/5

so

[tex]\frac{3}{5}m[/tex]

Answer:

 m    = (-9-3)/(1+7)

Step-by-step explanation:

To find the slope given two points we use

m = (y2-y1)/(x2-x1)

m    = (-9-3)/(1--7)

 m    = (-9-3)/(1+7)

m = -12/8

   = -3/2

Slope m has a form of,

[tex]m=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Your points say A and B have a form of,

[tex]A(x_1,y_1),B(x_2,y_2)\longrightarrow A(-7,3),B(1,-9)[/tex]

We can populate our slope formula to,

[tex]m=\dfrac{-9-3}{1-(-7)}=\dfrac{-12}{8}=\boxed{-\dfrac{3}{2}}[/tex]

The slope of the line that passes through point A and B is m = -3/2

-2    -3(1/2)^-2 = -12

-1     -3(1/2)^-1 = -6

0     -3(1/2)^0 = -3

Now, making the graph we will plot

(-2,-12), (-1,-6), (0,-3) and (1,-3/2)

The graph is shown in figure below.

To find g(x) values, substitute the x-values into the function equation. Calculate the result which gives you the y-value (g(x)) for each x-value. Plot these pairs of values on a graph to show the function's behavior.

To find the corresponding values of the function g(x), you need to substitute the x-values given into the function equation of g. For instance, if g(x) is a linear function given by y=3x+9, when x=1 the value of g(x) is 3*1+9=12, and this is the y-coordinate of the point plotted on the graph. Repeat this process with all the given x-values to get the corresponding y-values. Afterwards, plot all the (x, g(x)) pairs on the coordinate grid. The points are found at the intersection of the x and y (g(x)) values on the grid. After plotting, you can connect the points to give a graphical representation of the dependence of y on x.

Answer:

Always

Step-by-step explanation:

Given statement: Through a point not on a line, one and only one line can be drawn parallel to the given line.

Draw a line l.

Let point P not on the line l.

Slope of two parallel lines are same.

We need to draw a line which is passes through the point P and parallel to the line l.

Infinite number of lines having different slopes can pass through a single point.

That is two lines don't have same slope.

Hence only one line is possible, which is parallel to l and passes through the point P.

Therefore the given statement is always true.

Answer:

The average power use is 806 watts....

Step-by-step explanation:

We all know that there are 31 days in May.

To find the total number of hours in 31 days, multiply the hours of one day by 31.

31*24 = 744 hours

Now we have given 600.kilowatt

To find average power, simply divide the given kilowatt by the total number of hours in 31 days.

= 600/744

Average power = 0.806 kilowatt

Since they have asked for the answer in watts we will convert kilowatt into watts.

We know that 1000 watts = 1 kilowatt, so we will multiply 0.806 by 1000 to convert it into watts

= 0.806*1000

= 806 watts.

Therefore the average power use is 806 watts....
