Answer:

Annie's new job pays more an hour.

Step-by-step explanation:

They tell us that her new job pays $7.25 per hour. So to determine which job pays her more, we need to find how much she earns in her current job.

There are a few ways to find this (none of them are hard.) But this is the easiest way in my opinion.

The chart tells you that Annie earns $13 in 2 hours. We need to find how much she earns in 1 hour. All you need to do is divide $13 by two.

13/2 = 6.5

6.5 = $6.50

If her current job pays her $6.50 an hour and her new job pays $7.25 an hour, she should consider higher paying jobs.

But, yes, the new job pays her more an hour.

Slope = -5/2

Y-intercept = -9

Step-by-step explanation:

Hello!

The equation is given in Slope-Intercept Form: y= mx + b

Since the slope is the coefficient of the x-term, the slope of this equation is -5/2, or -2.5

The y-intercept is the numerical constant, which is given the by the integer -9.

If Robert bought a used car for $10,332 with an added sales tax of 2.5%. Then the original price of the car would be around $10,080.

Option (B) is correct.

What is a percentage?

A percentage is a relative value that represents the hundredth part of any quantity. One percent (symbolized 1%) is the one-hundredth part; thus, 100 percent represents the entire amount and 200 percent specifies twice the given amount.

Robert bought a used car for $10,332 with an added sales tax of 2.5%.

so the additional amount would be = 10,332 * 2.5%

                                                           = 10332 * 0.025

                                                           = $258.3

So the original price of the car would be = 10332 - 258.3

                                                                    ≈ $10,080.

Hence, If Robert bought a used car for $10,332 with an added sales tax of 2.5%. Then the original price of the car would be around $10,080.

The economy's nominal GDP in 2006 and real GDP in 2010 is option B)  Nominal GDP in 2006 $1,000, Real GDP in 2010 = $2,000.

What does GDP Price Index mean?

Nominal GDP in 2006=$1,000;

Real GDP in 2010=$2,000

Price index = (nominal GDP/real GDP) ×100

thus, nominal GDP in 2006=(price index × real GDP)/100

= (100×$1,000)/100

=$1,000

Real GDP in 2010= (nominal GDP/price index) ×100

= ($2,200/110) ×100

=$2,000.

Using theoretical probability, the probability of selecting green ball is 3/11, not selecting green ball is 8/11, selecting orange ball is 6/11 and not selecting orange ball is 5/11.

In the given question,

A bag has 2 red, 3 green, and 6 orange balls.

So total number of balls = 2+3+6 = 11

We have to find the theoretical probability.

(a) We have to find the theoretical probability of selecting green ball.

P(G) = Total number of green balls/Total number of balls

P(G) = 3/11

Hence, the probability of selecting green ball is 3/11.

(b) Now we have to find the theoretical probability of not selecting green ball.

Except green ball there is having red and orange i.e.

Total remaining balls except green = 2+6 = 8

P(G) = Total number of balls except green balls/Total number of balls

P(G) = 8/11

Hence, the probability of not selecting green ball is 8/11.

(c) Now we have to find the theoretical probability of selecting orange ball.

P(G) = Total number of orange balls/Total number of balls

P(G) = 6/11

Hence, the probability of selecting green ball is 6/11.

(d) Now we have to find the theoretical probability of not selecting orange ball.

Except orange ball there is having red and green balls i.e.

Total remaining balls except orange = 2+3 = 5

P(G) = Total number of balls except orange balls/Total number of balls

P(G) = 5/11

Hence, the probability of not selecting orange ball is 5/11.

By using the graphing method, a solution to the given system of equations is equal to -6 and -6.

In Mathematics, a graph can be defined as a type of chart that is typically used to graphically represent data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate and y-coordinate respectively.

Next, we would simplify the equation as follows:

4u = 2v - 12

Dividing both sides of the equation by 4, we have:

4u/4 = (2v - 12)/4

u = v/2 - 3

By critically observing the graph of this system of equations, we can logically deduce that the point of intersection is at (-6, -6).

The distance between point (12,6) and the line y = x - 14 is given as follows:

5.6 feet.

The standard equation of a line is given by the rule presented as follows:

ax + by + c = 0.

The coordinates of the point which we want to find the distance from the line are given as follows:

(x0,y0).

The equation that obtains the shortest distance of the point (x0, y0) to the line ax + by + c = 0 is presented as follows:

[tex]D = \frac{|a(x_0) + b(y_0) + c|}{\sqrt{a^2+b^2}}[/tex]

The line for this problem is given by the rule presented as follows:

y = x - 14.

In standard notation, it is defined by the rule presented as follows:

x - y - 14 = 0.

Hence the coefficients are presented as follows:

a = 1, b = -1, c = -14.

The point has the coordinates given as follows:

(12,6).

Hence:

x0 = 12, y0 = 6.

Thus the distance from the point to the line is obtained as follows:

[tex]D = \frac{|a(x_0) + b(y_0) + c|}{\sqrt{a^2+b^2}}[/tex]

D = |1(12) -1(6) - 14|/sqrt(1²+(-1)).

D = 8/sqrt(2)

No,  the slope of a horizontal line y=6 is,  zero not negative.

What is a Slope?

In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.

The net change in y-coordinate is represented by Δy and the net change in x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,

m = change in y/change in x = Δy/Δx

Where “m” is the slope of a line.

Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter ‘m’.

Slope Formula

If P(x1,y1) and Q(x2,y2) are the two points on a straight line, then the slope formula is given by:

Slope, m = Change in y-coordinates/Change in x-coordinates = Δy/Δx

m = (y2 – y1)/(x2 – x1)

In the given equation of line y=6 .

The line crosses the y-axis at 6, as the line is always at that value. As it is a horizontal line, the slope is zero.

The equation y = 6 means for each and every value of x, y will be equal to 6.

This is the definition of a horizontal line.

By definition, the slope of a horizontal line is m = 0

When x = 0 then y = 6

Therefore, the y-intercept is: (0, 6).

Hence , the the slope of a horizontal line , m = 0.

From equation (i)

-9(10-4y) + 2y = 24  [as x = 10-4y]

=> -90 +36y + 2y = 24

=> 38y = 90 + 24

=> 38y = 114

=> y = 114/38

Therefore, y = 3

Again,

x = - 8 is not a root of √(x + 12) - 6 = x, since it is an extraneous solution.

In this question we have a radical equation that offer two possible roots. A root is an extraneous solutions when it brings out an absurd (i.e. 1 = 4) when the expression is evaluated. First, write the radical equation:

√(x + 12) - 6 = x

Second, use algebra properties to find the possible roots of the radical equation:

√(x + 12) - 6 = x

√(x + 12) = x + 6

x + 12 = x² + 12 · x + 36

x² + 11 · x + 24 = 0

(x + 3) · (x + 8) = 0

x = - 3 or x = - 8

Third, evaluate the radical equation at each root:

√(- 3 + 12) - 6 = - 3

√9 - 6 = - 3

3 - 6 = - 3

- 3 = - 3 (TRUE)

√(- 8 + 12) - 6 = - 8

The proportionality constant is the ratio that connects two given values in a proportional relationship. The constant of proportionality is also known as the constant ratio, constant rate, unit rate, constant of variation, or even the rate of change.

When two or more parameters are directly or indirectly proportional to one another, their relationship is expressed as a = kb or a = k/b, where k indicates the nature of the relationship between the two variables. This k is referred to as the proportionality constant.

For example, the number of apples in a crop is proportional to the number of trees in an orchard, with the ratio of proportionality being the average number of apples per tree.

This can be illustrated as:

Let's say y = 4

Let's say x = 2
