The system of equations y = 3x - 7 and 6x - 2y = 12 has no solution. That is the lines of the equation is parallel.

To solve a system of equations, you can use substitution or elimination.

One method to find the solution for this system of equations is substitution. To use this method, you can solve one equation for one variable in terms of the other variable, and then substitute this expression into the other equation.

Solving for y in the first equation:

y = 3x - 7

Then substitute the result in the second equation:

6x - 2(3x - 7) = 12

6x - 6x + 14 = 12

14 = 12

That clearly is not true and this system of equations has no solution.

B) The value of r would not change

Step-by-step explanation:

If there's a positive association between sodium and calories, that's like saying there's a positive association between calories and sodium. Therefore, the value of r would not change because both variables are still increasing with each other.

The formula for a directed line segment is A = (x2 - x1, y2 - y1). It is a vector equation, meaning that it describes the direction and magnitude of a line segment, rather than its endpoint coordinates.  

A directed line segment is a line segment with a starting point and an ending point, where the direction of the line can be described in terms of its magnitude and direction. To calculate the directed line segment, first calculate the difference between the x-coordinates of the start and end points, and then calculate the difference between the y-coordinates of the start and end points. The result is the vector A, which describes the magnitude and direction of the line segment.

For example, consider a line segment with start point (1, 2) and end point (4, 6). To calculate the directed line segment, first calculate the difference between the x-coordinates of the start and end points (4 - 1 = 3). Then, calculate the difference between the y-coordinates of the start and end points (6 - 2 = 4). The result is the vector A = (3, 4). This vector describes the magnitude and direction of the line segment, with the magnitude being the length of the line segment, and the direction being the direction from the start point to the end point.

A triangle having an area of 142. 74 ft^2 and a height of 18. 3 ft, has a base of 15.6 ft.

What is the area of a triangle?

In a two-dimensional plane, a triangle's area is the area that it completely encloses. A triangle is a closed shape with three sides and three vertices, as is common knowledge. The entire area occupied by a triangle's three sides is referred to as its area. Half of the product of the triangle's base and height provides the general formula for calculating the area of the triangle.

The area of the triangle is 142.74 ft^2.

The height of the triangle is 18.3 ft.

Let the base of the triangle be x.

The formula for area of a triangle is -

Area = (height × base)/2

Plugging in the values in the equation -

142.74 = (18.3 × x)/2

142.74 = 18.3x/2

18.3x = 285.48

x = 285.48/18.3

x = 15.6

Therefore, the base of the triangle measures 15.6 ft.

Answer:

The game ends at 2:17 PM.

Step-by-step explanation:

The basketball game started at 10 hours and 50 minutes and the game lasted 3 hours and 27 minutes. We can use addition to find out the time. Simply add the hours and the minutes.

10 hours + 3 hours = 13 hours

50 minutes + 27 minutes = 77 minutes = 1 hour and 17 minutes

⇒ 14 hours and 17 minutes ⇒ 2:17 PM

Nolan would expect to earn $157 in a day when he waits in 12 tables.

Now, According to the question:

We have the following information:

Each day Nolan works, Nolan will make a guaranteed wage of $25, however the additional amount that Nolan earns from tips depends on the number of tables he waits on that day. From past experience, Nolan noticed that he will get about $11 in tips for each table he waits on.

Now, for waiting on 12 tables, he will get the fixed amount of 25 dollars and the amount for 12 tables.

So, the total amount will be:

25+11 × 12

$157

Hence, Nolan would expect to earn $157 in a day when he waits in 12 tables.

Answer:

1.) m∠CEB = 90 degrees => The intersection is perpendicular

2.) m∠BCE = 40 degrees => 180 - (50 + 90)

3.) m∠ADE = 50 degrees => 180 - (40 + 90)

4.) DE = 6 ft => half of DB: 12/2

5.) CB = 10 ft => Using Pythagorean Theorem, solve:

                     =>  8² + 6² = CB²

                     =>  64 + 36 = CB²

On solving the provided question, we can say that the e slope of the linear regression prediction equation if a person with 12 years of schooling is 1.

When modeling the relationship between a scalar answer and one or more explanatory variables in statistics, linear regression is a linear method. Simple linear regression is used when there is only one explanatory variable. The procedure is known as multiple linear regression if there are numerous. A straight line is used to evaluate the relationship between the independent and dependent variables in a regression model known as simple linear regression. Both factors ought to be quantitative. The effect of the independent variable on the dependent variable is examined using simple linear regression. The second scenario, known as multiple linear regression, examines how various independent factors affect the dependent variable.

[tex]8\frac{1}{4}d =\frac{2}{11}[/tex]

a) Simplify both sides of the equation.

[tex]\frac{33}{4}d=\frac{2}{11}[/tex]

b) Multiply both sides by 4/33.

[tex](\frac{4}{33} ) \times (\frac{4}{33}d)=(\frac{4}{33}) \times (\frac{2}{11} )\\[/tex]

d = [tex]\frac{8}{363}[/tex]

[tex]8\frac{1}{4} \div d=\frac{2}{11}[/tex]

= [tex]\frac{33}{4d} =\frac{2}{11}[/tex]

a) Cross Multiply.

[tex](33)\times(11)=2\times 4d[/tex]

[tex](363) =8d[/tex]

b) Flip.

[tex]8d=(363)[/tex]

c) Divide both sides by 8

[tex]\frac{8d}{8} = \frac{363}{8}[/tex]
