The graph of a two-variable inequality is the set of points that describe all solutions to the inequality. The graph of an inequality is shown below:

What is an inequality equation?

The coordinate plane is split in half by a boundary line created by a linear inequality, with one-half representing the solutions to the inequality.

It's a line with a shaded side on one side to show which xy pairings are the inequality's solutions.

Example -

Let us take an equation, 4x + 8y ≤ -24

Now, solve the above equation in the form of slope-intercept.

4x + 8y ≤ -24

or, 8y ≤ - 4x - 24

or, y ≤ -(1/2)x - 3

Now, the graph becomes according to the slope-intercept form is:

Here we noticed that,

This side of the inequality is shaded below (instead of above) because y is lower than (or equal to) the other side.

Because working with a "or equal to" inequality, draw a solid line rather than a dashed one. Points on the solid line denote locations where the inequality has been solved.

Answer:

A=6a2=6×(5)2=6×25=150cm2.

Step-by-step explanation:

The slope of 4y =- 4 is zero.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

Slope-intercept form:

y = mx+b,

where m is the slope and b is the y-intercept.

Given equation:

4y =- 4

To find the slope:

First, we simplify the equation.

Divide by 4.

(4/4)y = -4/4

y = -1

Now, we know the slope-intercept form:

y = mx+b,

where m is the slope and b is the y-intercept.

Comparing, both the equation,

we get,

m = 0.

So, the slope is 0.

Therefore, the slope is 0. This produces a horizontal line.

Answer:

B

Step-by-step explanation:

A = 0.5kg (Not close)

B = 0.05

C = 0.02 ( Not close)

D = 0.04

(Explanation why answer is B and not D)

B is closet because even we round off to two decimal places 0.05kg answer comes not 0.04kg

Plus 0.05 is 0.01kg away from 0.049, While 0.04kg is 0.09kg away from 0.049kg.

I hope my answer helps you.

1/20 kg is closest to 0.049 kg among the given choices. So, correct option is B.

To determine which option is closest to 0.049 kg, we can compare the given options to the target value and find the option with the smallest absolute difference.

A. ½ kg = 0.5 kg (Difference = |0.5 kg - 0.049 kg| ≈ 0.451 kg)

B. 1/20 kg = 0.05 kg (Difference = |0.05 kg - 0.049 kg| = 0.001 kg)

C. 1/50 kg = 0.02 kg (Difference = |0.02 kg - 0.049 kg| ≈ 0.029 kg)

D. 2/50 kg = 0.04 kg (Difference = |0.04 kg - 0.049 kg| = 0.009 kg)

Comparing the absolute differences, we can see that option B (1/20 kg = 0.05 kg) has the smallest difference from 0.049 kg, which is only 0.001 kg.

Therefore, option B (1/20 kg) is closest to 0.049 kg among the given choices.

When dealing with questions like this, it is helpful to compare the values using the absolute difference from the target value. The option with the smallest absolute difference is the closest approximation to the target value. In this case, 1/20 kg provides the closest value to 0.049 kg, making it the correct choice.

Step-by-step explanation:

Average number of planes that will stack up waiting to land:  This can vary greatly depending on the size of the airport, the number of flights per day, and the number of runways available.

What is average?

Average, mean, median, and norm all refer to something that sits in the middle. The average is the ratio created by dividing the total number of figures in a set by the total number of figures.

To determine the average number of planes that will stack up waiting to land, we need to know the rate at which planes arrive at the airport and the rate at which they are able to land.

Generally, an airport can expect to experience a queue of up to 10 planes waiting to land at peak times.

Average time a plane must wait in line before it can land: This also varies significantly depending on the airport and the conditions. Generally, a plane must wait an average of 5-7 minutes before it is able to land.

Average time it takes a plane to clear the runway once it has notified the airport that it is in the vicinity and wants to land: This time will depend on the size of the airport, the number of planes in the queue, and the amount of time it takes for the plane to taxi off the runway. Generally, a plane can expect to clear the runway in about 2-3 minutes.

And we need to find the measure of the longest side of ∆ABC is units.

Here we have to take the points A and B and then we need to find the distance for the points AB,

AB = √(-2 - 7)² + (2 - 1)²

AB = √(-9)² + (1)²
