A line passes through point (2, 5) and has a slope of 3. Write an equation in Ax +By=C form for this line. Use integers for A, B, and C. ​

Answers

Answer 1

Answer:

[tex]3\, x + (-1)\, y = 1[/tex].

Step-by-step explanation:

Both the slope of this line and the coordinates of a point on this line are given. Therefore, start by finding the point-slope equation of this line: if the slope of a line in a plane is [tex]m[/tex], and this line goes through a point at [tex](x_{0},\, y_{0})[/tex], the point-slope equation of this line will be [tex](y - y_{0}) = m\, (x - x_{0})[/tex].

The slope of the line in this question is [tex]m = 3[/tex]. It is given that this line goes through the point [tex](2,\, 5)[/tex], where [tex]x_{0} = 2[/tex] and [tex]y_{0} = 5[/tex]. Substitute in these values to find the point-slope equation of this line:

[tex](y - y_{0}) = m\, (x - x_{0})[/tex].

[tex](y - 5) = 3\, (x - 2)[/tex].

Rewrite this point-slope equation in the requested format:

[tex]y - 5 = 3\, x - 6[/tex].

[tex]3\, x - 6 = y - 5[/tex].

[tex]3\, x = y + 1[/tex].

[tex]3\, x - y = 1[/tex].

[tex]3\, x + (-1)\, y = 1[/tex].

Graph the points on the coordinate plane and connect them with a straight line.

Answers

A graph of the points on the coordinate plane with a straight line is shown in the image attached below. An equation in slope-intercept to represent the relationship is y = 125x + 500.

How to calculate the slope of a line?

In order to determine the equation of this line in slope-intercept, we would first of all calculate its slope. Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope,\;m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope,\;m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

Substituting the given points into the formula, we have;

Slope, m = (3,000 - 1,750)/(20 - 10)

Slope, m = 1,250/10

Slope, m = 125.

Mathematically, the standard form of the equation of a straight line is given by;

y - y₁ = m(x - x₁)

Where:

m represents the slope.x and y are the points.c represents the intercept.

At point (10, 1,750), we have;

y - 1,750 = 125(x - 10)

y - 1,750 = 125x - 1,250

y = 125x - 1,250 + 1,750

y = 125x + 500

Answer:

Step-by-step explanation:

there is a .9987 probability that a randomly selected 27-year old male lives through a year. a life insurance company charges $154 for insuring that the male will live through the year. if the male does not survive the year, the policy pays out $100,000 as a death benefit

Answers

Using probability we know that the expected value of the insurance company is $141.

What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution.

So, the expected value of the insurance company:

Probability = 0.9987So, 1.0000 - 0.9987 = 0.0013

Now, get the expected value as follows:

E(x) = 0.9987 × 154 + 0.0013(-9987)E(x) = 153.7998 + (-12.9831)E(x) = 153.7998 - 12.9831E(x) = 140.8167

Rounding off: $141

Therefore, using probability we know that the expected value of the insurance company is $141.

The slope of the line can be calculated using the points (2,2) and (6,10):

[tex]\begin{gathered} m=\frac{10-2}{6-2} \\ =\frac{8}{4} \\ =2 \end{gathered}[/tex]

Since the point (a,8) should belong to the same line, the slope should be the same using the points (a,8) and any other point. Since the slope is 2, use the points (a,8) and (2,2):

[tex]\begin{gathered} 2=\frac{8-2}{a-2} \\ =\frac{6}{a-2} \end{gathered}[/tex]

We got this expression for a:

[tex]2=\frac{6}{a-2}[/tex]

Take the reciprocal of both sides of the equation:

[tex]\frac{1}{2}=\frac{a-2}{6}[/tex]

Multiply both sides by 6:

[tex]\begin{gathered} \frac{6}{2}=a-2 \\ \Rightarrow a-2=3 \end{gathered}[/tex]

The x-intercept is 7.

y-intercept

The y-intercept is the value where the line crosses the y-axis.

We calculate this by setting x=0

[tex]\begin{gathered} \text{When x=0} \\ -x+2y=-7 \\ -0+2y=-7 \\ 2y=-7 \\ Divide\text{ both sides by 2} \\ \frac{2y}{2}=-\frac{7}{2} \\ y=-3.5 \end{gathered}[/tex]

Joe has 3/4 cup of paint in a container. He uses 1/3 cup on a project and then adds another 1/2 cup. How much paint does he have now?​

Answers

Answer:

Step-by-step explanation:

The cup of paint he has now is  11/12.

What is the amount of paint he has now?

We are basically going to add or subtract the quantity of cup added or used respectively.

Initially, he has 3/4 cup of paint.

He uses 1/3 cup out of the 3/4 cup of paint, so we subtract 1/3 from 3/4:

= 3/4 - 1/3 = 5/12

He adds another 1/2 cup, so we add 1/2 to what we have left previously (5/12):

= 5/12 + 1/2 = 11/12

Therefore, the amount of paint he has now is 11/12 cup

Answer: A

Step-by-step explanation: to find the base price, you would do 82.5 to give you a rate of 0.0727 (repeating) book per dollar. then if you do that with 7 and 8 in the same table, t gives you the same rate so A would be the answer.

Answer:

A

Step-by-step explanation:

We don't actually need to do any math to figure this out. We can use process of elimination and logical thinking.

we know it's not B because the prices are too close to each other, there is also the fact that 3 books should cost half of 82.50, and 15.75 isn't half of 82.50.

it's not D because 21 books cannot cost 33.75 dollars if 6 books cost 82.50.

it's not c because 12 books should be double the cost of 82.50, which it isn't.

therefore it must be A

Step-by-step explanation:

7x + 19 [tex]\leq[/tex] 12

Is the inequality you are trying to solve.

When solving an inequality, we solve it like a regular equation and do inverse operations by looking at the number and doing the opposite of whatever its operation is. Whatever happens on one side happens to the other. So you would first subtract 19 on both sides.

1. 7x + 19 [tex]\leq[/tex] 12

the reason we subtracted was because the opposite operation to addition is subtraction as the number 19 had had a plus sign behind it

Find all of the zeros of this function and use them to sketch a rough graph.

Answers

The zeroes of the function f(x) = x⁵ - 8x³ - 9x are x = 0, 3, - 3, i, and - i.

Consider the function,

f(x) = x⁵ - 8x³ - 9x

x⁵ - 8x³ - 9x = x( x⁴ - 8x² - 9 )

Factoring: x⁴ - 8x² - 9

The coefficient of x⁴ is 1, the coefficient of -8x² is - 8, and - 9 is the constant term.

x⁴ - 8x² - 9 = x⁴ - 9x² + x² - 9 = x²( x² - 9 ) + 1( x² - 9 )

x⁴ - 8x² - 9 = ( x² - 9 ) ( x² + 1 )

So,

x⁵ - 8x³ - 9x= 0

x( x⁴ - 8x² - 9 ) = 0

x( x² - 9 ) ( x² + 1 ) = 0

x( x - 3 )( x + 3 ) ( x² + 1 ) = 0

Therefore, the zeroes of the function are:

x = 0, x = 3, x = - 3, and

x² + 1 = 0

x² = - 1

Simple interest ( SI) is the interest earned on a certain principal at a certain rate over a certain period of time,

If P is the principal, rate is r %, time is t years,

SI = [tex]\frac{p \times r \times t}{100}[/tex]

Adding Principal and simple interest will give the amount

In this question, we have been given the approximate average distance from the sun to Neptune and Mercury.

Mercury : 5.79 × 10^9 kilometers

Neptune : 4.5 × 10^7 kilometers

We need to find how much Mercury is closer to the sun.

To find the distance by which Mercury is closer to the sun, consider the difference (5.79 × 10^9) - (4.5 × 10^7)

In the above difference the exponents of 10 are different.

So, we consider the 10^7

we write 5.79 × 10^9 as 579 × 10^7

So the difference would be,

(579 × 10^7) - (4.5 × 10^7)

= (579 - 4.5) × 10^7

= 574.5 × 10^7 km

= 5.745 × 10^9 km

Therefore, the Mercury is 5.745 × 10^9 kilometers closer to the sun.

Systems may be complex, such as a whole planet, or simple, such as the water inside a pot. The universe outside the system is called the surroundings. A closed system is one that does not exchange matter with its surroundings and does not experience any outside forces. An open system, on the other hand, can exchange matter with its surroundings and does experience outside forces.The idea of systems and surroundings was not always part of physics. In 1824, the French physicist Nicolas Carnot applied the idea of systems to thermodynamics. A little later, German physicist Rudolf Clausius added the idea of surroundings. Today, system and surroundings are terms applied also to mechanical systems, as well as used in other scientific fields such as biology.Examples of open systems are common in everyday life. A car driving down a road is a system. The car engine produces exhaust, which is matter passed to its surroundings. Friction between the car and the road is an outside force that acts on the system. Closed systems are rare in everyday life. They are commonly used in physics laboratories to simplify system analysis and calculations.So, what questions can help someone decide whether the system under consideration is open or closed? The first question to ask is: Does the system exchange matter with its surroundings? If yes, it is an open system. If no, it is a closed system.
