Making a graph of linear inequalities is similar to making a graph of linear equations. But with inequalities, we find a region instead of a line.

What is linear inequality?

Linear inequalities are mathematical statements that are made up of two expressions which are compared using inequality symbols.

The following steps are to be followed to make a graph of linear inequality:-

1. Solve the inequality for y.

2. Considering the inequality as a linear equation graph the line. ( If the inequality sign does not contain an equal sign then draw a dashed line; if the inequality contains an equal sign then draw a solid line.

3. Shade the region that satisfies the inequality.

Hence, a system of linear inequality is graphed similarly to that of a linear equation, but a region is obtained.

The branch of mathematics concerned with specific functions of angles and their application to calculations. In trigonometry, there are six functions of an angle that are often utilised. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their names and acronyms (csc).

Given:

2. P= x

H= 13 cm

Using Trigonometry

sin 52 = P/ H

sin 52 = x/ 13

x= 13 sin 52.

3. P = n, B= m and H= l

Using Trigonometry

cos <N= B/H

cos <N=  m / l

m = l cos <N

and, using Pythagoras theorem

H² = P² + B²

l²= m² + n²

m= √( l² - n²)

4. P = 7m

Answer:

Option A) m^9.

Step-by-step explanation:

To simplify the given expression, we can use the rules of exponents which state that when we multiply powers with the same base, we can add their exponents.

So, m² ∙ m⁶ ∙ m can be simplified as:

m² × m⁶ × m = m^(2+6+1) = m^9

Therefore, the simplified form of m² ∙ m⁶ ∙ m is m^9.

the equation fro the line can be written in the slope-intercept form,

for that we would need to find the slope and the y intercept on the line,

the slope can be found by using two of the points from the line.

the points we are selecting are (20,32) and (30,45) which are points that are approximate to the line drawn.

use the points given and the definition of the slope to find it:

It should look something like this

according to the graph the intercept is the point it crosses the y-intercept which in this case is 10.

the equation of the line will be

Using the equation of the line construct the data table by giving the values for x

0-10-20-30-40-50

it should look like this

in order to find the y side we use the equation, i will do an example with x as 10

apply the same to find the corresponding value to each x.

finish by making the exact graph for the equation and data table we just found

Answer:

Step-by-step explanation:

Let J be Jaxson's age.

According to the problem, Jaxson's mom is 35, which is three times as old as Jaxson. So, we can write:

Jaxson's mom's age = 3 times Jaxson's age

35 = 3J

To find Jaxson's age, we can solve for J by dividing both sides of the equation by 3:

35/3 = J

Jaxson's age is approximately 11.67 years old (rounded to two decimal places).

Answer:

4.28%

Step-by-step explanation:

We Know

Last year you earned $72,400

This year you earned $75,500

What was the rate of change in your earnings since last year?

We Take

(75,500 ÷ 72,400) x 100 ≈ 104.28%

Then We Take

104.28 - 100 = 4.28%

So, the earning increased by about 4.28%.

The regression equation is:

\(y=3.77+0.36 x\)

Step-by-step explanation:

The general form of a regression equation is:

\(y=\alpha +\beta x\)

Here,

α = intercept

β = slope

Compute the value of intercept and slope as follows:

\(\begin{aligned} \alpha &= \frac{\sum{Y} \cdot \sum{X^2} - \sum{X} \cdot \sum{XY} }{n \cdot \sum{X^2} - \left(\sum{X}\right)^2} = \frac{ 29 \cdot 186 - 28 \cdot 173}{ 5 \cdot 186 - 28^2} =3.767\approx 3.77 \\ \\\beta &= \frac{ n \cdot \sum{XY} - \sum{X} \cdot \sum{Y}}{n \cdot \sum{X^2} - \left(\sum{X}\right)^2} = \frac{ 5 \cdot 173 - 28 \cdot 29 }{ 5 \cdot 186 - \left( 28 \right)^2} =0.363\approx 0.36\end{aligned}\)

The regression equation is:

\(y=3.77+0.36 x\)

Answer:

(-1,10)

Step-by-step explanation:

At the point when the paths cross, the respective x and y values of each equation will be equal.

Your path is y=2x+12, and your friends path is 4x+y=6. Sub 2x+12 in for y (from your path's equation) into your friends equation to find the value of x:

4x+2x+12=6

6x=-6

x=-1

y=2x+12

y=2(-1)+12=10

So you will cross paths at (-1,10)

The z-score for 71 is -1.

z-score is a measure of how many standard deviations an observation or data point is away from the mean of a distribution.

It is calculated by subtracting the mean from the observation and then dividing the result by the standard deviation: z = (x - μ) / σ

A positive z-score means that the data point is above the mean, while a negative z-score means that it is below the mean.

Applying the formula to solve our question

Here is a proven formula to use:

z = (x - μ) / σ

where:

x = the data item (x = 71)

μ = the mean of the distribution (μ = 80)

σ = the standard deviation of the distribution (σ = 9)

Substituting the values, we get:

z = (71 - 80) / 9

z = -1

The value of y in simplest form for the point P = (1/2, y) lying on the unit circle is y = ± √(3)/2.

To find the value of y in simplest form for the point P = (1/2, y) lying on the unit circle, we can use the equation of the unit circle, which states that for any point (x, y) on the unit circle, the following equation holds: x^2 + y^2 = 1.

Plugging in the coordinates of the point P = (1/2, y), we get:

(1/2)^2 + y^2 = 1

1/4 + y^2 = 1

y^2 = 1 - 1/4

y^2 = 3/4.

To simplify y^2 = 3/4, we take the square root of both sides:y = ± √(3/4).

Now, we need to simplify √(3/4). Since 3 and 4 share a common factor of 1, we can simplify further: y = ± √(3/4) = ± √(3)/√(4) = ± √(3)/2.

The total number of family members will be 30.

Let's call the total number of family members "x".

From the information given:

x - 10 family members won't go to the park

x - 8 family members won't go to the beach

x - 12 family members won't go to the family cottage

4 family members will go to neither park nor beach

6 family members will go to neither beach nor family cottage

7 family members will go to neither park nor family cottage

So, the total number of people who won't go to either park, beach, or family cottage is 4 + 6 + 7 = 17

And the total number of people who will go to one or two of these three places is x - (10 + 8 + 12 + 17) = x - 47

The total number of family members will be:

x - 47 - 17 = 0

x - 30 = 0.

The quotient of  10⁻⁴/10² is 10⁻⁶

Quotient is the result obtained by dividing one quantity by another. It represents the value that is obtained after division.

For example, if you divide 20 by 2, the quotient is 10 because 20 divided by 2 equals 10.

Division law states that:

10ᵃ / 10ᵇ = 10ᵃ⁻ᵇ
