Step-by-step explanation:

Let's put the equation into point slope for 

-3y < -2x + 12

Divide by -3

y < 2/3x - 4

The answer is the first one because the shades are pointing down.

y < -3 means the shade points down y because y is less than -3

The inequality 2x – 3y <12 and y < –3 is shown in the third graph.

Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.

The inequalities are:

2x -3y ≤ 12

y < -3

First, for the second inequality, we can see that y must be strictly less than -3, so we should see a dotted line at y = 3, and a shaded section under that line.

From this, we can discard the second graph (the middle one).

The first inequality can be rewritten as:

2x - 3y ≤ 12

-3y ≤ 12 - 2x

Now we divide by -3 into both sides, as we are dividing by a negative number, the direction of the ≤ sign changes:

y ≥ (12/-3) + (-2/-3)x = -4 + (2/3)*x

This means that the shaded section must be above the line:

y = -4 + (2/3)*x

Therefore, the inequality 2x – 3y <12 and y < –3 is shown in the third graph.

The profit made as a function of x ;

Let :

Number of units produced = x

Profit per unit = $3

Fixed cost = $17,000

The total profit as a function of x is P(x) = 3x - 17,000

(A) The profit is $43,000

(B) The loss is $2,000

The given parameters;

The following equations will be set up as follows;

Total cost price = 17,000 + x(y)

Total selling price = x(y + 3)

The total profit as a function of x is calculated as;

total Profit = total selling price - total cost price

total Profit = x(y+3) - 17,000 - xy

total Profit = xy + 3x - 17,000 - xy

total Profit = 3x - 17,000

P(x) = 3x - 17,000

(A) The profit or loss when x = 20,000 units are produced;

Step-by-step explanation:

\( \frac{average \: distance \: Earth \: to \: the \: Sun}{average \: distance \: from \: Earth \: to \: the \: Moon} = \frac{1.49 \times {10}^{8} }{3.8 \times 10} \)

\( = 3.92 \times {10}^{6} \)

The average distance from Earth to the Sun is approximately 392 times greater than the average distance from Earth to the Moon.

To determine how many times greater the average distance from Earth to the Sun is compared to the average distance from Earth to the Moon, we can divide the distance to the Sun by the distance to the Moon.

Average distance from Earth to the Sun: 1.49 x 10⁸ km

Average distance from Earth to the Moon: 3.8 x 10⁵ km

So, to calculate the ratio, we divide the distance to the Sun by the distance to the Moon:

Answer:

The first one

Step-by-step explanation:

In mathematics, the term linear function refers to two distinct but related notions: In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one. So going in that order gives you a linear function.

A linear function increases at a constant rate of change, which means that for every 1 unit that x changes, y always changes at a same rate.

For example, if x moves 1, y moves 5 constantly. Every time x moves 1, y moves 5.

In this case every time x in the first table increases by 1, y increases by 6, so that is a linear function.

The second table is not linear because when x increases by 1,  y decreases by 1. But the second time, when x increases by 1, y decreases by 2! -2 is not equal to -1.

The third and fourth tables are not linear for the same reasons.

Answer:

the explanatory variable is "the amount of practice every year" while the response variable is "the improvement in his game"

Step-by-step explanation:

In simple terms, the difference between explanatory and random variable is that the response variable is usually the focus of a question in a study/experiment while an explanatory variable is a variable that explains changes in the response variable. Which means that the explanatory variable is simply any variable that may affect the response variable.

Now, in this question, the golfer wants to determine if the amount of practice every year can be used to predict the amount of improvement in his game.

This means that the amount of practice every year explains how much he improves every year.

Thus, the explanatory variable is "the amount of practice every year" while the response variable is "improvement in his game"

The fifth percentile of the standard normal distribution is -1.64.

In the given question, we have to determine the fifth percentile of the standard normal distribution as a decimal rounded to the nearest hundredth.

The standard normal distribution, commonly known as the z-distribution, is a unique type of normal distribution in which the mean and standard deviation are both equal to 1. Any normal distribution's values can be transformed into z scores to normalise it. Z score shows the amount of standard deviations from the mean that each consists of numbers.

Since, X is normally distributed.

P(X< c) = 0.05

Using Z table

c = -1.645

Fifth percentile = -1.64

The new dimension of the rectangular field are 45 ft by 120ft.

If the field has originally dimensions length L and width W, and we apply a scale factor K, then the new dimensions of the rectangle are:

lenght = K*L

width = K*W

In this case the original dimensions are:

L = 30ft

W = 80ft

And the scale factor is K = 1.5, then the new dimensions are:

L' = 1.5*30ft = 45ft

The angle measures for this problem are given as follows:

The sum of the measures of the internal angles of a triangle is of 180º.

The triangle in this problem is ABC, hence the measure of a is obtained as follows:

a + 68 + 50 = 180

a = 180 - (68 + 50)

a = 62º.

c and d are corresponding angles to angle a, as they are on the same position relative to parallel lines, hence their measures are given as follows:

Angle b is a corresponding interior angle with angle a, hence they are supplementary and it's measure is given as follows:

a + b = 180

62 + b = 180

The correct equivalent expression to the square root containing a variable is 2a³/5 and the correct option is E.

We shall simplify the expression of the square root containing a variable by carrying out basic mathematics operations to derive its equivalent as follows:

squre root of (36a⁸/255a²) = square root of (36a⁶ × a²/255 × a²)

a² is common and can be cancel out

square root of (36a⁸/255a²) = square root of (36a⁶/255)

square root of (36a⁸/255a²) = square of 36 multiplied by the square root of a⁶ all divided by the square root of 255 {take square root of each}

square root of (36a⁸/255a²) = 6a³/15

square root of (36a⁸/255a²) = 2a³ × 3/5 × 3

we divide through by the common factor 3

square root of (36a⁸/255a²) = 2a³/5

Therefore, the equivalent expression to square root of (36a⁸/255a²) is derived as 2a³/5 which is option E.

Answer:

y=7/-1x-2

Step-by-step explanation:

Answer:

y = - 2x + 13

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 2, thus

y = - 2x + c ← is the partial equation

To find c substitute (7, - 1) into the partial equation

- 1 = - 14 + c ⇒ c = - 1 + 14 = 13

y = - 2x + 13 ← equation of line

Answer: Option A, 192 sqft.

Step-by-step explanation:

The area of a parallelogram is given as A = b * h. Where A = area of a parallelogram, b = base of a parallelogram, and h = height of a parallelogram.

As given in the picture above we can see that the height of the parallelogram is 12 ft and the base is 16 ft.

so Area is the base multiplied by the height. that is A = 16 ft * 12 ft which is equal to 192 ftsq. A parallelogram has for sides and two opposite sides that are parallel and also have equal lengths. The height of a parallelogram is the perpendicular distance between two parallel lines of a parallelogram.

We can use the following equation to find the area of a parallelogram:

\(A=bh\)

We're given:

Plug these values into the equation and solve:

\(A=bh\\A=16*12\\A=192\)

Therefore, the area of the parallelogram is 192 ft².

192 ft²

The solution set of this inequality is {x| x > -6.1}

Here we have the inequality:

2x + 8 > -4.2

To find the solution set, we need to isolate the variable x in one of the sides of the inequality. Doing that we will get:

2x + 8 > -4.2

2x > -4.2 - 8

2x > -12.2

x > -12.2/2

x > -6.1

So the set of all numbers larger than -6.1, this in number form is:
