Answer:

The answer is D

Step-by-step explanation:

2(n+6)=20

2 times n equals 2n

2 times 6 equals 12

so, 12 plus 2n equals 20

make 2n the subject of formula so, 2n= 20-12 (the sign will change when coming past the (=) sign

2n= 8

n=2/8

n=4

Answer:

J = 11/4

Step-by-step explanation:

J + 17/4 = 7

7 as a fraction

7 x 4 = 28

28/4

J + 17/4 = 28/4
J + (17/4 - 17/4) = (28/4 - 17/4)

J = 11/4

Answer:

j = 11/4

Step-by-step explanation:

For quick answer just in your head multiply 4 by 7, which is 28. Then subtract 17 since that’s the given, which you will get 11. So j = 11/4. Hope this somewhat makes sense.

To solve for the value of j, we need to isolate j on one side of the equation.

First, we can simplify the left side of the equation by multiplying both sides by 4 to get rid of the fraction:

j + 17/4 = 74(j + 17/4) = 4(7)

4j + 17 = 28

Next, we can isolate j by subtracting 17 from both sides:

4j + 17 - 17 = 28 - 174

j = 11Finally, we can solve for j by dividing both sides by 4:

j = 11/4

Therefore, the value of j that satisfies the equation is j = 11/4.

we can check whether j = 11/4 is the correct solution by substituting it into the original equation and seeing if it is true.

j + 17/4 = 7

When we substitute j = 11/4, we get:

(11/4) + 17/4 = 7

Simplifying the left side of the equation, we get:

28/4 = 7

Both sides of the equation simplify to 7, which means that the solution j = 11/4 is correct.

To further verify, we can also add 11/4 and 17/4 to get:

11/4 + 17/4 = 28/4 = 7

Since we obtained the same value for both sides of the equation, we can conclude that the solution j = 11/4 is correct.

Answer: A′(0, 0), B′(−2, 5), C′(5, 5), D′(3, 0)

Step-by-step explanation:

Because since it is 90 degrees counterclockwise you would do the 270 formula since it is counterclockwise and the formula for 270 degrees is basically swapped the x and the y and add a negative to the original y and if it's already a negative it becomes a pthe polygon, so the answer is A (0, 0), B(-2, 5), C(5, 5), D(3, 0) the first one credits too : Kfn032409

Sure! Here's an example set of data that is a function:

| x | y |

|---|---|

| 1 | 3 |

| 2 | 5 |

| 3 | 7 |

| 4 | 9 |

| 5 | 11 |

To show that this is a function, we need to check that for every value of x, there is only one corresponding value of y. We can see from the table that this is true - for example, when x=2, y=5 and there are no other values of x that give y=5.

To represent this function in the form y=m*x+b, we need to find the values of m and b. We can use the slope-intercept form of a line to do this, which is:

y = m*x + b

where m is the slope of the line and b is the y-intercept (the value of y when x=0).

To find the slope, we can use the formula:

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

where (x1, y1) and (x2, y2) are any two points on the line. Let's use the points (1, 3) and (2, 5):

m = (5 - 3) / (2 - 1) = 2

So the slope of the line is 2.

To find the y-intercept, we can use any point on the line and solve for b. Let's use the point (1, 3):

y = m*x + b

3 = 2*1 + b

b = 1

So the y-intercept is 1.

Now we can write the equation of the line in slope-intercept form:

y = 2*x + 1

To check that this equation matches the values in the table, we can substitute each value of x into the equation and see if we get the corresponding value of y:

When x=1: y = 2*1 + 1 = 3

When x=2: y = 2*2 + 1 = 5

When x=3: y = 2*3 + 1 = 7

When x=4: y = 2*4 + 1 = 9

When x=5: y = 2*5 + 1 = 11

These values match the values in the table, so we have shown that the set of data is a function and we have written its equation in the form y=m*x+b.

Sure, here is a set of data that is a function using at least 5 domain values and 5 range values:

```

Domain | Range

------- | --------

-2 | -4

-1 | -3

0 | -2

1 | -1

2 | 0

```

This data can be shown in a table, a graph, or a set of ordered pairs. In this case, we will show it as a table:

```

| Domain | Range |

|---|---|

| -2 | -4 |

| -1 | -3 |

| 0 | -2 |

| 1 | -1 |

| 2 | 0 |

```

We can use the equation y = m + b to find the slope (m) and y-intercept (b) of this function. The slope is calculated by finding the change in y (the range) divided by the change in x (the domain). In this case, the change in y is -4 - (-3) = -1, and the change in x is -2 - 0 = -2. Therefore, the slope is -1/-2 = 1/2. The y-intercept is calculated by finding the value of y when x is 0. In this case, the value of y is -2. Therefore, the y-intercept is -2.

The equation of this function is y = (1/2)x - 2. This function can be graphed by plotting the points in the table and connecting them with a line. The graph of this function is a straight line.

Step-by-step explanation:

Answer:

The approximate diameter of each tire on Jasmine's bicycle can be calculated by dividing the circumference by π (pi). Using the given circumference of 70.4 inches and rounding π to 3.14, the calculation would be as follows:Diameter = Circumference / π

Diameter = 70.4 / 3.14

Diameter ≈ 22.45 inches (rounded to the nearest hundredth)So, the approximate diameter of each tire on Jasmine's bicycle is 22.45 inches.

The approximate diameter of each tire is 22.42 inches.

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The circumference of a circle is expressed mathematically as;

C = 2πr

or

C = πd

Where r is radius, d is diameter, and π is constant pi ( π = 3.14 )

Rearrange this formula to solve for the diameter:

C = πd

d = C/π

Substituting the given value of the circumference, we have:

d = 70.4/3.14

d = 22.42 in

Therefore, the diameter is 22.42 in.

Answer:

741a + 825b + 639c = 1375/9.

Step-by-step explanation:

To solve this problem, we need to first find the values of a, b, and c that satisfy the given system of equations. We can use any method of solving systems of linear equations, such as substitution or elimination. Here, we will use the elimination method:

Multiplying the first equation by -4 and adding it to the second equation, we get:

-20b - 36c = -2

Multiplying the first equation by -7 and adding it to the third equation, we get:

29b + 45c = 8

Multiplying the second equation by -29/20 and adding it to the third equation, we get:

-21b - 39c = 67/10

Now we have three equations in two variables. We can solve for b and c using any method, such as elimination or substitution. Here, we will use substitution:

From the second equation, we can solve for a in terms of b and c:

a = (2 - 2b - 3c)/4

Substituting this expression for a into the third equation, we get:

741/4 - 825/2 b + 639/6 c = 9

Simplifying and solving for b, we get:

b = (3/5) - (3/5) c

If this helps, please mark my answer as brainliest

Substituting this expression for b into the second equation, we get:

(27/5) c = (2/5)

Solving for c, we get:

c = -(2/27)

Substituting this value of c into the expression for b, we get:

b = (3/5) - (3/5) (-2/27) = (11/27)

Substituting the values of a, b, and c into the expression 741a + 825b + 639c, we get:

741a + 825b + 639c = 741[(2 - 2b - 3c)/4] + 825b + 639c

= 741[(2 - 2(11/27) - 3(-2/27))/4] + 825(11/27) + 639(-2/27)

= 741(5/27) + 275/3 - 426/9

= 1375/9

Therefore, 741a + 825b + 639c = 1375/9.

Answer:

6 feet.

Step-by-step explanation:

The height of the given parallelogram would be; 6 feet.

What is the area of a parallelogram?

The area of a parallelogram is the product of the base and the height of the figure.

The area of a parallelogram = Base x Height

We have been given that the area of this parallelogram is 120 ft. then we need to find the value of h.

Base = 20 feet

Since, the area of a parallelogram = Base x Height

Area = 20ft x height

120ft = 20ft x height

The height = 120/20

Height = 6ft

Hence, the height of the given parallelogram would be; 6 feet.

Answer:

w≥77

Step-by-step explanation:

Multiply 11 by 7.

Answer:

[tex]w\geq 77[/tex]

Step-by-step explanation:

How would you get w by itself so that it makes it simplify?

Either you Multiply/Divide and Subtract/Add.

In your case you have [tex]\frac{w}{7} \geq 11[/tex]

To get w by itself you multiply 7 to both side leaving w.

[tex]7*\frac{w}{7}\geq 11*7[/tex]

Seven cancel out on the left side leaving w.

11 * 7 = 77.

[tex]w\geq 77[/tex]

Answer:

Step-by-step explanation:

Answer:

(A.) A triangle will be formed with vertices X, Y, and Z with side lengths XY = 18 mm, YZ = 20 mm, and XZ = 39 mm. This is because the sum of the lengths of any two sides of a triangle must be greater than the length of the third side according to the triangle inequality theorem. In this case, XY + YZ = 18 mm + 20 mm = 38 mm, which is greater than XZ = 39 mm, satisfying the triangle inequality theorem.

(B.) A triangle will be formed with vertices X, Y, and Z with side lengths XY = 17 mm, YZ = 20 mm, and XZ = 36 mm. This is because XY + YZ = 17 mm + 20 mm = 37 mm, which is greater than XZ = 36 mm, satisfying the triangle inequality theorem.

(C.) A triangle will not be formed with vertices X, Y, and Z with side lengths XY = 16 mm, YZ = 20 mm, and XZ = 37 mm. This is because XY + YZ = 16 mm + 20 mm = 36 mm, which is not greater than XZ = 37 mm, violating the triangle inequality theorem.

(D.) A triangle will be formed with vertices X, Y, and Z with side lengths XY = 17 mm, YZ = 19 mm, and XZ = 37 mm. This is because XY + YZ = 17 mm + 19 mm = 36 mm, which is greater than XZ = 37 mm, satisfying the triangle inequality theorem.
