What is the value of n? enter your answer in the box

n= ——- cm

Answer: False.

Step-by-step explanation: The two equations are not equivalent because the constant terms on the right side of each equation are different. The first equation has -20 on the right side, while the second equation has 0 on the right side. The equations cannot be manipulated into each other because the constant terms are different.

A line in the xy-plane passes through the origin and has a slope of 1/7 is 7y = x.

In the given question, we have to find a line in the xy-plane passes through the origin and has a slope of 1/7.

The equation of the line is:

y - y(1) = m(x - x(1))

The given points is (0, 0). So

x(1) = 0 and y(1) = 0

From the given question, m = 1/7

Now putting the value in the equation of line

y - 0 = 1/7(x - 0)

y = 1/7 x

Multiply by 7 on both side, we get

7y = x

Hence, a line in the xy-plane passes through the origin and has a slope of 1/7 is 7y = x.

40 minutes past 7:00 is the actual time when the chicken will get ready.

The tool used to measure and indicate time is a clock or timepiece. The clock, one of the earliest creations by humans, satisfies the need to measure time periods that are shorter than those represented by natural units like the day, lunar month, and year. Over thousands of years, several physical processes have been utilized by devices.

The following examples of clocks that are based on movement in nature could be regarded forerunners of the modern timepiece: Through the positioning of a shadow on a flat surface, a sundial displays the time.

The hourglass is a well-known illustration of the variety of duration timers available. The two possible oldest clocks used to measure time are sundials and water clocks.

In Europe, the earliest mechanical clocks that kept time with oscillating timekeepers such balance wheels were made possible around 1300 thanks to the development of the verge escapement, which was a significant advancement.

Given the current time is 10 minute past 7:00, i.e. 7:10

But the clock is 15 min faster the original time

Original time = 7:10 - 15 min

= 6:55

And given time for the chicken to get ready is 45 min

Adding 45 min

= 6:55 + 45 min

= 7:40

Thus, 40 minutes past 7:00 is the actual time when the chicken will get ready.

The slope of the line is undefined.

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (-4, 6) and (-4, 1)

Now,

Since, The equation of line passes through the points (-4, 6) and (-4, 1)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - 6) / (-4 - (-3))

m = - 5 / 0

Answer:

y=2

Step-by-step explanation:

Answer:

Step-by-step explanation:

A quadrilateral is cyclic if and only if the opposite angles are supplementary, or add up to 180 degrees. Angle ABC is equal to angle BCD in the diagram because they are opposing angles of a parallelogram.

Furthermore, because AB=BC, the opposite angles are congruent, which implies they are equal. Because angle ABC equals angle BCD, angle ABC Plus angle BCD equals 180 degrees. As a result, we may deduce that ABCD is a cyclic quadrilateral.

Another technique to demonstrate that ABCD is a cyclic quadrilateral is to use the theorem "In a parallelogram, opposite sides and opposite angles are equal."

A parallelogram has equal opposed sides and equal opposite angles. We know that AB=BC in this situation, thus AB and BC are opposing sides, implying that the quadrilateral is a parallelogram. And because the opposite angles are equal, the quadrilateral is cyclic.

As a result, the congruence of parallel sides and opposing angles establishes that the quadrilateral is a cyclic quadrilateral.

A fraction is a way of representing a part of a whole or a ratio of two numbers. It is written as a ratio of two numbers, called the numerator and the denominator, separated by a horizontal line or a slash.

Each sheet of sticker paper can be used to make 1/16 of a sheet of stickers, so two sheets of sticker paper can be used to make 2 * (1/16) = 2/16 = 1/8 of a sheet of stickers.
