May ha 4/15 meter of lace while lovie ha 2/7 meter longer Than may lace then 86/105 meter of lace do girl have altogether

Meter Definition

The meter is the standard unit of measuring length in the International System of Units (SI). Its symbol is “m” and it is one of the seven base units of the SI system.

May has 4/15 meters of lace

Lovie has a lace that is 2/7 meters longer

4/5 + 2/7

= 58/105

Therefore the lace they own together can be calculated as follows

= 4/15 + 58/105

= 86/105

Hence together they have 86/105 meters of lace

The simplest way to solve the system of equations 7x + 5y = 19 and -7x - 2y = -16 would be using the method of c i.e Elimination.

Elimination, also known as the method of adding or subtracting equations. This method involves adding or subtracting the equations in such a way that one of the variables is eliminated, making it easier to solve for the other variable.

Here is one way to solve the system of equations 7x + 5y = 19 and -7x - 2y = -16 using the elimination method:

Add the two equations together:

(7x + 5y) + (-7x - 2y) = 19 + (-16)

This eliminates the x variable and gives you:

3y = 3

Divide both sides of the equation by 3 to get:

y = 1

Substitute this value of y back into one of the original equations (either 7x + 5y = 19 or -7x - 2y = -16) to find the value of x. For example, using the first equation:

7x + 5(1) = 19

7x + 5 = 19

7x = 14

x = 2

So the solution to the system of equations is x = 2 and y = 1.

The absolute value f(x)=6|x| function as a piecewise-defined function is:

f(x) = { 6x, if x ≥ 0

        { -6x, if x < 0

A piecewise-defined function is a function that is defined by multiple sub-functions, each of which applies to a certain range of the input (or domain) values.

Each sub-function is defined by a separate piece of the overall function, and together they define the entire domain of the function. The sub-functions are typically separated by breakpoints, which are values of the input variable at which the sub-functions change.

|x| can either be -x or x. Thus, the absolute value function f(x) = 6|x|  can be written as:

f(x)= 6x or f(x)= -6x

Therefore, the piecewise-defined function of f(x) = 6|x| will be:

f(x) = { 6x, if x ≥ 0

The measure of the arc QP is QP = 66°.

What is inscribed angle?

In terms of geometry, an inscribed angle is the angle created when two chords intersect within a circle. It can also be described as the angle formed by two specified points on a circle at a given point on the circle. Two chords of the circle sharing an endpoint are equivalently used to define an inscribed angle.

Given:

m ∠ RPQ = 57°

We have to find the measure of the arc QP.

Since,

RQ = 2*m ∠RPQ

RQ = 2*(57°)

RQ = 114°

Let

 RP = RQ + QP

180° = 114° + QP

 QP = 180° - 114°

 QP = 66°

Hence, the measure of the arc QP is QP = 66°.

Answer:

y = (3/5)x+3.6

Step-by-step explanation:

Let's look for an equation of the standard form: y=mx+b, where m is the slope and b is the y-intercept (the value of y when x is 0).  Parallel lines have the same slope, m.  Next, rearrange the reference line to standard format:

  3x-5y=10

   -5y = -3x + 10

    y = (3/5)x + 2

Now we can easily find the slope.  The slope of the reference line is (3/5).  That will also be the slope of the parallel line, so we can write:

   y = (3/5)x + b

We need a value of b that will shift the line so that it touches point (-1,3) .  ["passes through"].  Enter that point into the above equation and solve for b:

   y = (3/5)x + b

   (3) = (3/5)*(-1) + b   for point (-1,3)

   3 = -(3/5) + b

 -(3/5) = 3-b

  -b = -3 - (3/5)

   b = 3+(3/5)

   b = (18/5), or 3.6

The equation becomes y = (3/5)x+3.6

See the attached graph.

To find the ordered pair (x, f(x)) of a function, you must first know the function's equation. The ordered pair is a combination of the input value (x) and the output value (f(x)) of the function.

Here are the steps to find the ordered pair of a function:

f(4) = 2(4) + 3 = 8 + 3 = 11

It's important to note that the ordered pair will be different for every input value (x) you substitute into the function's equation.

For instance, if you want the ordered pair of f(x) = 2x + 3 for x = 5 you will have (5,13) as an ordered pair.

It's also worth mentioning that in some cases you might have functions like[tex]f(x) = (x-2)^2 + 1[/tex], you can use the same process but you will be solving the equation rather than just substituting it.

There are several ways to calculate the slope of a line, but the most common ways are:

Rise over Run: This is the most basic and intuitive way to calculate slope. It involves taking the difference in the y-coordinates (rise) and dividing it by the difference in the x-coordinates (run) between two points on the line. The slope is represented by the letter "m" and can be calculated using the following formula: m = (y2 - y1) / (x2 - x1)

For example, if two points on a line are (3,6) and (6,9) the slope can be calculated as: m = (9-6) / (6-3) = 3/3 = 1

Point-Slope Form: This method uses the coordinates of a single point on the line and the slope of the line to find the equation of the line. The slope is represented by the letter "m" and the point by the coordinates (x1, y1). The equation of the line in point-slope form is: y - y1 = m(x - x1)

Slope-Intercept Form: This method expresses the equation of a line in the form of y = mx + b, where m is the slope and b is the y-intercept. To find the slope-intercept form, you need to know the slope and the y-intercept (the point where the line crosses the y-axis) of the line.

A standard deviation or (σ ) is a measurement of the data's dispersion from the mean. A low standard deviation indicates that data are concentrated around the mean, whereas a high standard deviation shows that data are more dispersed.

If the standard deviation is close to zero, the data points are close to the mean; otherwise, if the standard deviation is high or low, the data points are, respectively, above or below the mean.

We know that Ron's estimate for the number of messages he sent that day was 40% more than the actual number of messages he sent. To find out how many messages he estimated he sent, we need to undo this percentage increase.

If the actual number of messages Ron sent was 25, and his estimate was 40% more than that, we can use the following equation:

Estimated number of messages = Actual number of messages + (Actual number of messages * 40%)

We can then substitute in the known values and solve for the estimated number of messages:

Estimated number of messages = 25 + (25 * 40%)

Estimated number of messages = 25 + (25 * 0.4)

Estimated number of messages = 25 + 10

Estimated number of messages = 35

Therefore, Ron estimated that he sent 35 messages that day.

As a result, the cervix is ready for the baby to enter the delivery canal (vagina). Each woman's cervix thins and opens at a different rate. The cervix may begin to slowly efface and dilate over a few weeks in certain women. On the other hand, a first-time mother frequently won't dilate until active labor begins.

Your doctor may use his or her fingers to feel the cervix toward the end of your pregnancy to see how much it has effaced and dilated. To do this, he or she will put on sterile gloves.
