Please help! Explain how to find the slope and y-intercept by just looking at the equation y=1/3x-2. Then graph the equation and verify your answers.

Answer: gavin scored 465 points

Step-by-step explanation:

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).

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.

Answer: x = -2, y = 3

Step-by-step explanation:

Given that,

-9x+2y = 24..................................(i)

x = 10-4y.......................................(ii)

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 = 10 - 4(3)  [as y = 3]

=> x = 10-12

Therefore, x = -2

Here, x = -2 and y = 3

The percentage increase for the money the class has raised is 10% and they will need $ 2115 to make the percentage increase to 99%.

According to the question,

We have the following information:

Initial price in the year = $1500

Final price they have = $1650

a) Now, we know that following formula is used to find the percentage increase in the price:

Percentage increase = 100*(final price-initial price)/initial price

Percentage increase = 100*(1650-1500)/1500

Percentage increase = 100*(150)/1500

Percentage increase = 10%

b) Now, we will find the final price when the percentage increase is 99%.

Let's take the final price to be $x.

99 = 100*(x-1500)/1500

99 = (x-1500)/15

Using the cross multiplication method:

x-1500 = 15*99

x-1500 = 615

x = 615+1500

x = 2115

Hence, the percentage increase for the money the class has raised is 10% and they will need $ 2115 to make the percentage increase to 99%.

Answer:

She will pay the same amount at both

Step-by-step explanation:

For Life Studio,

the initial sign up fee + $30 each month

= $30 = 30 × 6 = $180

Hence, $60 + $180 = $240

For Yoga Mind,

$40 each month for 6 months

= $40 × 6

$40 × 6= $240

Therefore, she will pay the same amount at both

The equation of the horizontal line passing through the point (2, -6) is :

y = -6

and the equation of the vertical line passing through the point (2, -6):

x = 2

We need to write equations for the horizontal and vertical lines passing through the point (2, -6)

For a vertical line the value of x will never change. This will be true for any value of y.

So, the equation for a vertical line passing through this point is:

x = 2

Similarly, for a horizontal line the value of y will never change. This is true for any value of x.

So, the equation for a horizontal line passing through this point is:

y = -6

Therefore, the equation of the horizontal line passing through the point (2, -6) is y = -6

and the equation of the vertical line passing through the point (2, -6) is x = 2

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.

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

Step-by-step explanation:

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

y = kx

4 = 2k

Divide

k = 4/2

k = 2

a. Matching with the country: 362,880, using the arrangements formula.

b. Not matching with the country: 60,949,324,800, using the permutation formula.

The number of possible arrangements of n elements is obtained by the factorial of n, that is:

[tex]A_n = n![/tex]

For item a, the arrangements formula is used, as the banner has to match the country, hence only the countries are arranged and then the specific banner is matched with this country.

Considering that there are nine countries, the number of ways of selecting and matching nine banners with a country is calculated as follows:

Total = 9! = 362,880.

The number of possible permutations of x elements from a set of n elements is obtained by the equation as follows:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

For item b, 9 banners are taken from a set of 20, and the permutation formula is used as the order in which the banners are chosen is important, hence the number of ways of selecting nine banners without having to match them with a country is obtained as follows:

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).
