Answer:  this is in a fraction: X = 16/5, decimal form: x = 3.2, and in a mix number: x = 3 1/5

Step-by-step explanation:

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Answer:

[tex]y=\frac{c-ax}{b}[/tex] is the answer

Step-by-step explanation:

ax+by=c

subtracting ax on both sides

ax-ax+by=c-ax

by=c-ax

dividing b on both sides

by/b=[tex]\frac{c-ax}{b}[/tex]

[tex]y=\frac{c-ax}{b}[/tex]

Answer:

4:3

Step-by-step explanation:

divide 8 by 2 and 6 by 2

8/2:6/2

4:3

Hi there!

Answer:

4:3

Step-by-step explanation:

Here is how we simplify a ratio:

1.Find the greatest common factor in both of the numbers

2.Divide both of the numbers by that factor.

3. And than your done solving the problem!

*******************************************************************

You have to divide both numbers by 2 because the GCF of 8 and 6 is 2

Remember; GCF means Greatest Common Factor...

8/2=4

6/2=3

Since we got 4 and 3...

The answer would be 4:3

So, 8:6 would equal to 4:3

Also if you want to simplify you have to divide and make it the smallest number you can!

If we simplify 8:6 it will be 4:3 but we can’t simplify 4:3 so that will be the answer.

(Note; Half of 8 is 4 and half of 6 is 3 so we know that’s correct, it’s also a way you can check your work)

~Have a great day!~

If you have any questions, feel free to ask! :)

Answer:

8, 2, 8, 2

7, 3, 7, 3

6, 4 6, 4

9, 1, 9, 1

Step-by-step explanation:

In the picture, it shows two of each number so I'm gonna base it off the picture but let me know if I should base it off the wording.

So we know that half of 20 is 10. This will be valuable information. So we need the sum of two numbers to equal 10. So for the rows we can just do 8+2+8+2, 7+3+7+3, 6+4+6+4, 9+1+9+1.

Since there are 18 numbers, I'm assuming we don't have to use all of them.

Answer:

9, 1, 9, 1

2, 8, 2, 8

3, 7, 3, 7

6, 4, 6, 4

Step-by-step explanation:

you would have to have the numbers repeat so it works, for instance, you could do 9,1,9,1 as the first row then 2,8,2,8 as the second row and for the third row you could do 3,7,3,7 and for the fourth row you could do 6,4,6,4 so both the columns and rows add to 20

Answer:

number of hours worked equation

The observed amount are At x = 7.9, y = $33.50 and at x = 25.00, y = $25.00 predicted amount are At x = 7.9, y = $26.37 and At x = 12.1, y = $27.63 and residuals are $7.13 and -$2.63.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

Observed amount:

At x = 7.9, y = $33.50

At x = 25.00, y = $25.00

We have a line of best fit:

y=0.3x+24.00

At x = 7.9

Predicated amount:

y = $26.37

At x = 12.1

Predicated amount:

y = $27.63

Residual (when x = 7.9)  = $33.50 - $26.37 = $7.13

Residual (when x = 12.1) = $25.00 -  $27.63 = -$2.63

Thus, the observed amount are At x = 7.9, y = $33.50 and at x = 25.00, y = $25.00 predicted amount are At x = 7.9, y = $26.37 and At x = 12.1, y = $27.63 and residuals are $7.13 and -$2.63.

Answer:

If you are given 3 vertices of a parallelogram, as a Geometry student, you will be asked to find the exact coordinates of the 4th vertex.  Just so that you can put your mind at ease, there can be different answers depending on how you decide to "draw" or "shape" your parallelogram.  So if your answer is different than another student, it does not mean that you have done it incorrectly.

Suppose I am given 3 points as such, and I am looking for the coordinates of D:

A (2, 3)

B (8, 1)

C (11, 5)

D (x, y)

The line segments that make up our parallelogram is AD is parallel to BC, and CD is parallel to AB.  Since the definition of a parallelogram is a quadrilateral with 2 pairs of parallel sides, we can use this fact to find the coordinate to the 4 vertex.  A pair of parallel side also means that these 2 lines have the same slope.  So if we do this on both pairs of parallel lines, we should have 2 equations with 2 variables, which should be simple to solve.

Slope of CD = Slope Slope of AB

(y - 5)/(x - 11) = (1 - 3)/(8 - 2)

(y - 5)/(x - 11) = -2/6

6(y - 5) = -2(x - 11)

6y - 30 = -2x + 22

equation #1:  6y + 2x = 52

Slope of AD = Slope of BC

(y - 3)/(x - 2) = (5 - 1)/(11 - 8)

(y - 3)/(x - 2) = 4/3

3(y - 3) = 4(x - 2)

3y -9 = 4x - 8

equation #2:  3y - 4x = 1

We now we have 2 equations with 2 variables, and we can use any method (substitution, linear combination, matrix) to solve for the x and y coordinates.  

equation #1:  6y + 2x = 52

equation #2:  3y - 4x = 1

Multiply equation by -2

Equation 2: -2(3y - 4x = 1)

Equation 2:  -6y + 8x = -2

Add equation 1 to equation 2

equation 1:  6y + 2x = 52

equation 2:  -6y + 8x = -2

eq 1 + eq 2:  10x = 50

x = 5

Use any of the original equation to solve for y:

6y + 2x = 52

6y + 2(5) = 52

6y = 42

y = 7

So the 4th vertex for my first answer will be (5, 7)

If we draw the parallelogram in a different way using the given vertices, we will be looking for a different 4th vertex.  So in our original question:

A (2, 3)

B (8, 1)

C (11, 5)

D (x, y)

Our line segments in this case will be draw as such:

AC is parallel to BD and CD is parallel to AB.

Slope of AC = slope of BD

(5 - 3)/(11 - 2) = (y - 1)/(x - 8)

2/9 = (y - 1)/(x - 8)

2(x - 8) = 9(y - 1)

2x - 16 = 9y - 9

equation 1:  2x - 9y = 7

Slope of CD = slope of AB

(5 - y)/(11 - x) = (3 - 1)/(2 - 8)

(5 - y)/(11 - x) = 2/-6

-6(5 - y) = 2(11 - x)

-30 + 6y = 22 - 2x

equation 2:  2x + 6y = 52

Solve the following linear system:

equation 1:  2x - 9y = 7

equation 2:  2x + 6y = 52

eq 1 - eq2:  -15y = -45

-15y = -45

y = 3

Substitute y = 3 into any one of the original equation:

equation 1:  2x - 9y = 7

2x - 9(3) = 7

2x - 27 = 7

2x = 34

x = 17

So by drawing the parallelogram in a different way, the 4th vertex of this parallelogram is (17, 3).

Step-by-step explanation:

See Answer

The fourth coordinate for the given parallelogram will be (5, 7).

A basic quadrilateral with two sets of parallel sides is known as a parallelogram.

A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.

There are 4 types of parallelograms, including 3 special types. The four types are parallelograms, squares, rectangles, and rhombuses.

Given the parallelogram ABCD are A(2, 0), B(4, 3), C(3, 1).

Now,

The slope of AB = Slope of CD

(y - 5)/(x - 11) = (1 - 3)/(8 - 2)

6(y - 5) = -2(x - 11)

⇒  6y + 2x = 52 will be the first equation.

Now,

The slope of BC = Slope of AD

[(y - 3)/(x - 2)] = [(5 - 1)/(11 - 8)]

[(y - 3)/(x - 2)] = 4/3

3(y - 3) = 4(x - 2)

⇒ 3y - 4x = 1 will be the second equation.

Now, By substitution

x = 5 and y = 7

Hence "The fourth coordinate for the given parallelogram will be (5, 7)".

Step-by-step explanation:

Answer:

Line 1 and Line 2: Neither -- slopes are not same (one is negative one is positive)

Line 1 and Line 3: Perpendicular -- Line 3's slope is the negative reciprocal of Line 1's

Step-by-step explanation:

Lines are parallel if they have the same slope but different y-intercept.

Lines are perpendicular if the slopes are negative reciprocals.
