if (-4,5) is the only solution to a system of two linear equations, then the graphical solution would show:

Answers

Answer 1

What shape do linear equations make? To picture the solution visually, you can imagine two of those shapes meeting on a graph at one (and only one) point, (-4,5).

Answer 2

Final answer:

The graphical solution to a system of two linear equations with the point (-4,5) as the only solution will show two lines intersecting at this point on a two-dimensional graph.

Explanation:

If the point (-4,5) is the only solution to a system of two linear equations, this means that the two lines represented by these equations intersect at this point. On a Two-Dimensional (x-y) Graphing system, this point would be plotted on the graph where the x-coordinate is -4 and the y-coordinate is 5.

These two equations when plotted as lines in a two-dimensional space (with x as the independent variable and y as the dependent variable) will intersect at this point (-4,5). If you draw a line from the origin to the point (-4,5), it will intersect the two lines at this point. This is how the graphical solution would look like.

what percent of 176 is 17.6

Answers

10%

To find 100% percent sure, multiply 17.6 *10

17.6 * 10 = 176

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 176 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 176 is 100%, so we can write it down as 176=100%.
4. We know, that x is 17.6% of the output value, so we can write it down as x=17.6%.
5. Now we have two simple equations:
1) 176=100%
2) x=17.6%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
176/x=100%/17.6%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 17.6% of 176

176/x=100/17.6
(176/x)*x=(100/17.6)*x - we multiply both sides of the equation by x
176=5.6818181818182*x - we divide both sides of the equation by (5.6818181818182) to get x
176/5.6818181818182=x
30.976=x
x=30.976

now we have:
17.6% of 176=30.976

Hello, I am taking Quantitative methods for business, which has a lot of excel based mathematics and I was wondering if anyone could help. Here is the question:

Refer to the table that illustrates customer’s complaints about a manufacturing company.

A. What is the probability a customer complained during the guarantee period?

B. What is the probability that a customer complained about an electrical problem or a mechanical problem?

Table is included in attachment. Also Thank you!!!

Answers

Part A:

The probability that a customer complained during the guaranteed period is given by the number of costumers that complained during the guarantee period devided by the total number of students.

Therefore, the probability that a customer complained during the guaranteed period is [tex] \frac{1,890}{3,000} = \frac{63}{100} [/tex]

Part B:

The probability that a customer complained about an electrical problem or a mechanical problem is given by the sum of the probability that the customer complained about an electrical problem or the probability that the customer complained about a mechanical problem.

Therefore, the probability that a customer complained about an electrical problem or a mechanical problem is [tex] \frac{900}{3,000} + \frac{1,050}{3,000} = \frac{1,950}{3,000} = \frac{13}{20} [/tex]

The sum of two integers is greater than 12. One integer is 10 less than the other. What are the values of the integers?

Answers

Let's set up an equation:

x plus y is greater than 12

x + y > 12

One of the integers is ten less than twice the other one

x = 2y -10

Time to start solving:

(2y-10) + y > 12
2y + y > 12 + 10
3y > 22
3y=24
y=8

Now its time to find the value of x:

x=2(8) - 10
x=16-10
x= 6

6 + 8 > 12, 6+8 is greater than twelve.

In conclusion we can wrap up that 6 and 8 are the least value integers.

Given that the restaurant is located in a city with a population over 500,000, what is the probability that it is in the northeast?

Answers

The probability is 0.187 or 18.7% that the restaurant chosen at random is in the north east and is located in a city with a population over 500,000.

To find the likelihood that a haphazardly picked eatery from the 588 outlets situated in a city with a populace more than 500,000 is in the north east, we really want to know the quantity of cafés that meet these two rules and are situated in the north east.

Let's look for this information using the table:

Northeast Midwest South West More than 500,000 Over 500,000 110 95 178 66 Less than 500,000 53 39 38 9 The table indicates that 110 restaurants are located in the north east of the United States in cities with more than 500,000 residents. In this manner, the likelihood that a haphazardly picked eatery from the 588 outlets situated in a city with a populace more than 500,000 is in the north east is:

P(Northeast and North of 500,000) = 110/588 = 0.187

Thus, the likelihood is 0.187 or 18.7% that the café picked aimlessly is in the north east and is situated in a city with a populace more than 500,000.

Write the point-slope form of the equation of the line passing through the points (-5, 6) and (0, 1).

B) y – 6 = -1(x + 5)
C) y + 6 = 1(x – 5)
D) y – 6 = 1(x + 5)

Answers

The point slope form:
[tex]y - y_1 = m(x - x_1)[/tex]

We need to find the slope. To find the slope we can use the following formula:
[tex]\frac{y_2 - y_1}{x_2 - X_1}[/tex]

Use the points (-5, 6) and (0, 1) and plug it into our slope formula and solve:
[tex]\frac{1 - 6}{0 - (-5)}[/tex]
[tex]\frac{-5}{5} = -1[/tex]

So our slope is -1 which means m = slope = -1
Now that we have our slope lets create the point slope form

Our point slope form equation is [tex]y - y_1 = m(x - x_1)[/tex] Remember
m = slope = -1. Also, we are going to use the point (-5,6).

First insert the m = slope = -1 number where m is located
[tex]y - y_1 = -1(x - x_1)[/tex]

Next, insert the -5 from (-5,6) where [tex]x_1[/tex] is located and the 6 from (-5,6) where [tex]y_1[/tex] is located.
[tex]y - y_1 = -1(x - x_1)[/tex]
[tex]y - 6 = -1(x - (-5))[/tex]
Now simplify
[tex]y - 6 = -1(x - (-5))[/tex]
[tex]y - 6 = -1(x +5)[/tex] <-------Answer

The point-slope form of the equation of the line passing through the points (-5, 6) and (0, 1) is [tex]$ \boxed{A) y + 6 = -1(x - 5)} $[/tex].

To find the point-slope form of the equation of the line passing through the points (-5, 6) and (0, 1), we first need to calculate the slope (m) using the formula:

[tex]\[ m = \frac{y_2 - y_1}{x_2 - x_1} \][/tex]

Given points:

[tex]$(-5, 6)$ and $(0, 1)$[/tex]

Calculate the slope m:

[tex]\[ m = \frac{1 - 6}{0 - (-5)} = \frac{-5}{5} = -1 \][/tex]

Now that we have the slope m = -1, we can use the point-slope form of the equation of a line, which is:

[tex]\[ y - y_1 = m(x - x_1) \][/tex]

Choose one of the points, let's use [tex]$(-5, 6)$ as $(x_1, y_1)$[/tex]:

[tex]\[ y - 6 = -1(x + 5) \][/tex]

Now, simplify and compare with the given options:

[tex]\[ y - 6 = -1(x + 5) \][/tex]

So, the point-slope form of the equation of the line passing through the points (-5, 6) and (0, 1) is [tex]$ \boxed{A) y + 6 = -1(x - 5)} $[/tex].

Answers

6 rolls of dimes = $30.

6 rolls of quarters = $60.

Answer:

7 roll of quarter and 4 roll of dimes.

Step-by-step explanation:

Let x be the number of rolls of quarters and y be the number of rolls of dimes,

Given,

Total rolls = 11

⇒ x + y = 11 ------(1),

Also, the total value of $ 90 in which Each roll of quarters has a value of $10 and each roll of dimes has a value of $5.

⇒ 10x + 5y = 90 ------(2),

Equation (2) - 5 × Equation (1),

We get,

5x = 90 - 55

⇒ 5x = 35 ⇒ x = 7

From equation (1),

7 + y = 11 ⇒ y = 4

Hence, the number of roll of quarters = 7,

And, the number of roll of dimes = 4

Answer: The required probability that the child took a green marble is 40%.

Step-by-step explanation: Given that there are 9 red and 6 green marbles in a bag and a child reaches in the bag and randomly takes one marble.

We are to find the probability that the child took a green marble.

Let S denote the sample space of choosing a marble from the bag and A be the event of choosing a green marble.

Then,

n(S) = 9 + 6 = 15 and n(A) = 6.

Therefore, the probability of event A will be

[tex]P(A)=\dfrac{n(A)}{n(S)}=\dfrac{6}{15}=\dfrac{2}{5}\times 100\%=40\%.[/tex]

Thus, the required probability that the child took a green marble is 40%.
