Answer:

OP = 4

Step-by-step explanation:

N is the midpoint of MO.

Since NO = 3, then MN = 3, and MO = 3 + 3 = 6

MO + OP = MP

6 + OP = 10

OP = 4

A line segment is also a line but the line with finite length and having fixed endpoints. The length of the line segment OP is 4 units.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.

Given the following details as:

Now, from the figure, We have,

Since O is between M and P and N is the midpoint between MO

MP = MN + NO + OP _____(1)

Now,

N is the midpoint of MO so,

MN = N0

N0 = 3 and MP = 10 ____(2)

MN = NO = 3 _______(3)

From (1)

MP = MN + NO + OP

Substituting (2) and (3) in (1)

10 = 3 + 3 + OP

10 = 6 + OP

Subtracting 6 on both sides

10 - 6 = 6 + OP - 6

4 = OP

OP = 4

Thus, OP = 4.

Answer:

(0, 5 )

Step-by-step explanation:

The y- intercept is where the function crosses the y- axis.

This occurs when x = 0 , thus

From the table when x = 0 , f(x) = 5 , thus

y- intercept is (0, 5 )

y- intercept is (0, 5 )

Answer:

y = x - 2

Step-by-step explanation:

8 + 5y = 5x - 2

5y = 5x -2 - 8

5y = 5x - 10

5y/5 = (5x - 10)/5

y = x - 2

The equation 5x - 2 = 8 + 5y can be written as in terms of x as y = x - 2; the answer is y = x - 2.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The equation is:

5x - 2 = 8 + 5y

The above equation represents the linear equation in one variable.

To solve for y make the subject as y

5y = 5x - 2 - 8

5y = 5x - 10

y = (5x - 10)/5

y = x - 2

Thus, the equation 5x - 2 = 8 + 5y can be written as in terms of x as y = x - 2; the answer is y = x - 2.

2.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using -19 as the denominator :

-29 -29 • -19

-29 = ——— = —————————

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

When a fraction equals zero

3.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

551-s

————— • 19 = 0 • 19

19

Now, on the left hand side, the 19 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

551-s = 0

Solving a Single Variable Equation:

3.2 Solve : -s+551 = 0

Subtract 551 from both sides of the equation :

-s = -551

Multiply both sides of the equation by (-1) : s = 551

Given:

Coordinates of point A are (2,8).

Point M(-2,2) is the midpoint of AC.

To find:

The coordinates of C.

Solution:

Let the coordinates of point C are (a,b).

Formula for midpoint:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Using the above formula, the midpoint of A(2,8) and C(a,b) is

[tex]M=\left(\dfrac{2+a}{2},\dfrac{8+b}{2}\right)[/tex]

[tex](-2,2)=\left(\dfrac{2+a}{2},\dfrac{8+b}{2}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{2+a}{2}=-2[/tex]

[tex]2+a=-4[/tex]

[tex]a=-4-2[/tex]

[tex]a=-6[/tex]

and,

[tex]\dfrac{8+b}{2}=2[/tex]

d = [tex]\sqrt{29}[/tex]

Step-by-step explanation:

[tex]d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\d= \sqrt{(1-(-1))^2+(-1-4)^2} \\d= \sqrt{(2)^2+(-5)^2} \\d= \sqrt{4+25} \\d=\sqrt{29}[/tex]

The distance between each pair of points (-1,4) and (1,-1) is √29 units after using the distance formula.

It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.

The distance formula can be given as:

[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

It is given that:

The distance between each pair of points (-1,4) and (1,-1)

Two points are (-1, 4) and (1, -1)

To find the distance between the above two points using the distance formula:

[tex]\rm d=\sqrt{(1-(-1))^2+(-1-4)^2}[/tex]

[tex]\rm d=\sqrt{(1+1)^2+(-1-4)^2}[/tex]

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division

d = √[(2)² + (-5)²]

d = √(4 + 25)

d = √29 units

Thus, the distance between each pair of points (-1,4) and (1,-1) is √29 units after using the distance formula.

Let's go through each option:

A. 5: Yes, 10x + 5 can be divided evenly by 5, as (10x + 5) ÷ 5 = 2x + 1.

B. 10: No, 10x + 5 cannot be divided evenly by 10, as 10 is greater than 10x + 5.

C. х (x): No, 10x + 5 cannot be divided evenly by x, as x is a variable and cannot be factored out completely.

D. 5x: Yes, 10x + 5 can be divided evenly by 5x, as (10x + 5) ÷ 5x = 2 + (1/x).

Answer:

24/32

Step-by-step explanation:

24/32 is the answer because:

1) We should first try to see if we can find a common denominator so it is easier to compare and find the larger number

2) The common denominator is 32 because 16 multiplied by 2 is 32 and 11 multiplied by 2 is 22. The new fraction is 22/32

3) Finally, compare 22/32 and 24/32, we know that 24 is bigger than 22. Therefore, 24/32 is greater than 11/16
