Write The Equation Of The Given Line In Slope-intercept Form.

Answers

Answer 1

Answer:

y = 2x - 1

Step-by-step explanation:

The line passes through points A(1, 1) and B(2, 3).

The slope-intercept form of the equation of a line is

y = mx + b,

where m = slope, and b = y-intercept.

We see from the graph that the y-intercept is -1, so b = -1, and we have

y = mx - 1

Going from point A to point B, we go up two units and right 1 unit. Slope = m = difference in y over difference in x, so

m = 2/1 = 2

The equation is

y = 2x - 1

Answer 2

Answer: 2x + -1

Step-by-step explanation: In this problem, we're asked to write the equation of the given line in slope-intercept form.

Slope-intercept form is the same thing as y = mx + b form where m represents the slope of the line and b represents the y-intercept. So our first step is to find the slope and the y-intercept of the given line.

To find the slope, we use the ratio rise over run between any two points on the line. To get from point A to point B along this line, we rise 2 units and run 1 unit. So our slope or rise over run is 2/1 or just 2.

Next, to find the y-intercept, it's important  to understand that the y-intercept is the point where the line crosses the y-axis. Notice that this line crosses the y-axis at the point (0,-1) which means that the y-intercept is -1.

Therefore, m = 1/2 and b = -1 and we substitute these values into our formula for m and b to get y = 2x + -1.

So the equation of the given line in slope-intercept form is y = 2x + -1.

Can someone give 2 examples of a logarithmic equation with infinite solutions?

Answers

Assuming what is meant by "infinite solutions" are infinite number of solutions of a logarithmic equation.  

[tex]\frac{1}{2}\log x^2 - \log \sqrt{x} - \log \sqrt{x} = 0[/tex]

and

[tex]\frac{1}{2}x-2\ln e^x=-\frac{3}{2}x[/tex]

Logarithmic equations with infinite solutions have graphs that look like dying-out exponentials. They can have infinite solutions because there are infinitely many values of y that satisfy the equation.

Examples of Logarithmic Equations with Infinite Solutions:
1. Logarithms to the base 10 (common logarithms):

In the equations below, y is the exponent to which 10 must be raised to equal x, so y is the common logarithm (log) of x.
x = 10^y
x = 10^y+1

2. Logarithms to the base e (natural logarithms):

In the equations below, y is the power to which e must be raised to equal x, so y is the natural logarithm (ln) of x.
x = e^y
x = e^y+1

Both of these equations have graphs that look like dying-out exponentials. They have infinite solutions because there are infinitely many values of y that satisfy the equation. Whenever the base is positive and not equal to 1, logarithmic equations can have infinite solutions.

a. y=-8/7x-3/2
b. y=-3/2x+7/8
c. y=-7/8x-3/2
d. y=7/8x-3/2

Answers

Answer:

C

Step-by-step explanation:

The slope intercept of a line is y=mx +b where

m is the slope which is calculated as the vertical distance divided by the horizontal distance between two points.b is the y-intercept for value on the y-axis for which the line crosses it.

This graph crosses the y-axis (the vertical line) halfway between -1 and -2. This  is -3/2. This means only answers a, c, and d are options.

The graph moves up from -3/2 to its next point at (-4,0). We calculate the slope using:

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

We substitute [tex]x_1=0\\y_1=-1.5[/tex] and [tex]x_2=-4\\y_2=2[/tex]

[tex]m=\frac{2-(-1.5)}{-4-0}[/tex]

[tex]m=\frac{2+1.5}{-4}=\frac{3.5}{-4} =-0.875[/tex]

This decimal is equivalent to -7/8. This means C is the answer.

PLEASE HELP ME! What is the equation of a line that passes through the point (6, 1) and is perpendicular to the line whose equation is y=−2x−6?


Enter your answer in the box.

Answers

Answer:

y=0.5x-2

Step-by-step explanation:

if it is perpendicular to the line y=-2x-6, then you know that its slope is the negative reciprocal of that line, and it has a different y intercept which you need to solve for using the point given. You solve by plugging in the x and y values from the point and plugging in the slope into the standard equation, and solving for b, the y intercept

y=0.5x+b

1=0.5(6)+b

1=3+b

-2=b


The equation of the line that passes through the point (6, 1) and is perpendicular to the line whose equation is y=−2x−6  is y = 0.5x - 2.

How to find equation of straight line from concept of perpendicular line ?

From the classic definition of straight lines, we know that if we have to find an equation of a straight line being perpendicular to another straight line then the slope of the new equation of straight lines becomes negative reciprocal of the slope of given perpendicular line.

Finding the equation of the required straight line -

Mathematically, let m1 be the slope of the new straight line and m be the slope of the given perpendicular line, then we have

m1 = -(1/m)

Now, we have given equation y = -2x - 6

Thus slope of the required equation is say (m1) = -(-1/2) = 0.5

Thus the equation formed is y = (m1)x + c [where c is the y-intercept]

∴ y = 0.5x + c

The point given is (6,1) , thus y = 1 and x = 6

Thus the given equation can be formed as

⇒ 1 =  0.5*6 + c

∴  c = 1 - 0.5*6 = -2

The value of y-intercept of the required straight line is -2

The equation of straight line formed is y = 0.5x - 2.

Thus the equation of the line that passes through the point (6, 1) and is perpendicular to the line whose equation is y = − 2x − 6  is y = 0.5x - 2.

Sketch the plane curve represented by the given parametric equations. Then use interval notation to give the relation's domain and range. X = 2t, y = t2 + t + 3

Answers

Answer:

Domain: [tex]( -\infty,\infty )[/tex] and Range: [tex][ -1,\infty )[/tex]

Step-by-step explanation:

We have the parametric equations [tex]x= 2t[/tex] and [tex]y=t^{2}+t+3[/tex].

Now, we will find the values of 'x' and 'y' for different values of 't'.

t                       :   -3       -2.5     -2     -1.5     -1     0       1      1.5      2

[tex]x= 2t[/tex]             :   -6       -5       -4       -3      -2    0      2      3        4

[tex]y=t^{2}+t+3[/tex]  :    9       6.75     5     3.75     3    3      5     6.75     9

Now, we can see that these parametric equations represents a parabola.

The general form of the parabola is [tex]y=ax^{2}+bx+c[/tex].

Now, we have the point ( x,y ) = ( 0,3 ). This gives that c = 3.

Also, we have the points ( x,y ) = ( -2,3 ) and ( 2,5 ). Substituting these in the general form gives us,

4a - 2b + 3 = 3 → 4a - 2b = 0 → b = 2a.

4a + 2b + 3 = 5 → 4a + 2b = 2 → 2a + b = 1 →  2a + 2a = 1 ( As, b = 2a ) → 4a = 1 → [tex]a=\frac{1}{4}[/tex].

So, [tex]b=\frac{1}{2}[/tex].

Therefore, the equation of the parabola obtained is [tex]y=\frac{x^{2}}{4}+\frac{x}{2}+3[/tex].

The graph of this function is given below and we can see from the graph that domain contains all real numbers and the range is [tex]y\geq -1[/tex].

Hence, in the interval form we get,

Domain is [tex]( -\infty,\infty )[/tex] and Range is [tex][ -1,\infty )[/tex]

Answer:

Domain:

[tex](-\infty,\infty)[/tex]

Range:

[tex][2.75,\infty)[/tex]

Step-by-step explanation:

we are given parametric equation as

[tex]x=2t[/tex]

[tex]y=t^2+t+3[/tex]

We can change into rectangular equation

we can eliminate t from first equation and plug into second equation

[tex]x=2t[/tex]

[tex]t=\frac{x}{2}[/tex]

now, we can plug that into second equation

[tex]y=(\frac{x}{2})^2+\frac{x}{2}+3[/tex]

now, we can draw graph

Domain:

we know that

domain is all possible values of x for which any function is defined

we can see that our equation is parabolic

and it is defined for all values of x

so, domain will be

[tex](-\infty,\infty)[/tex]

Range:

we know that

range is all possible values of y

we can see that

smallest y-value is 2.75

so, range will be

[tex][2.75,\infty)[/tex]

Jupiter has 11 more than 4 times as many moons has Neptune. Neptune has 14 moons. Let j equal the number of moons Jupiter has.

Answers

Final answer:

Jupiter has 67 moons.

Explanation:

To solve this problem, let's define j as the number of moons Jupiter has. According to the given information, Jupiter has 11 more than 4 times as many moons as Neptune, which has 14 moons. So, we can set up an equation: j = 4n + 11, where n is the number of moons Neptune has. Since Neptune has 14 moons, we can substitute that value into the equation: j = 4(14) + 11. Simplifying further, we get j = 56 + 11 = 67. Therefore, Jupiter has 67 moons.

solve 14^x+1=36
Round to the nearest ten-thousandth.

Answers

Answer:

x = 1.3472 to the nearest ten thousandth.

Step-by-step explanation:

14^x + 1 = 36

14^x = 35

Taking logarithms:-

x ln 14 = ln 35

x = ln 35 / ln 14

= 1.3472.

The solution, rounded to the nearest ten-thousandth, is x = 1.5404.

To solve the equation [tex]14^x + 1 = 36[/tex], we first isolate the exponential term by subtracting 1 from both sides of the equation, which gives us [tex]14^x = 35.[/tex]

The next step is to take the logarithm of both sides of the equation.

We could use any base for the logarithm, but it's common to use base 10 or the natural logarithm base (e). In this case, let's use the natural logarithm:

[tex]ln(14^x) = ln(35)[/tex]

We can then use the property of logarithms which allows us to bring the exponent down as a multiplier:

[tex]x * times ln(14) = ln(35)[/tex]

Now, you can solve for x by dividing both sides by ln(14):

[tex]x = ln(35) / ln(14)[/tex]

Using a calculator, we find the quotient and then round to the nearest ten-thousandth:

x = 1.5404

This value is the solution to the original equation.

Last year my family decided to put on a play It was A Great success . 200 people attended and we earned a total of 800 . If adults tickets cost 4 and children coat 2 dollar , how many adults were there

Answers

Answer:

200 adults

Step-by-step explanation:

We can set-up a system of equations to find the number of adults. We know children and adults attended. We will let c be the number of children and a be the number of adults. Since 200 people attended, then c+a=200.

We also know they made $800 and adult tickets cost $4 and child tickets cost $2. We can write 2c+4a=800.

We will solve by substituting one equation into the other. We start by solving the first equation for c. c+a=200 becomes c=200-a.

Now we substitute c=200-a into 2c+4a=800. Simplify and isolate the variable a.

2(200-a)+4a=800400-2a+4a=800400+2a=800400-400+2a=800-4002a=400a=200

This means that 200 adults attended and 0 children attended.

You are going to flip a coin 8 times. The first 3 times you flip the coin you get tails. What is the probability that all the remaining flips will also be tails?

Answers

Answer:

So when you flip the coin 8 times and you get tails 3 of the times then you should do 3 plus 5 and you will get 8 as your total again so then the answer is 5 out of 8 total.

Step-by-step explanation:


Final answer:

The probability that all the remaining flips will be tails is 1/32, or approximately 0.03125.

Explanation:

The probability of getting tails on each coin flip is 50 percent since a fair coin has two equally likely outcomes: heads or tails.

If the first three coin flips resulted in tails, the remaining five coin flips are independent events. The probability of getting tails on each of the remaining flips is still 50 percent.

The probability of getting all the remaining flips to be tails is calculated by multiplying the probabilities of each individual flip. Since there are five remaining flips, the probability is 0.5 raised to the power of 5, or 1/32 (approximately 0.03125).

The research study done to find the average age of all U.S. factory workers where the researchers asked every factory worker in Ohio their birth year is an example of a census. A census involves gathering information about every individual in the entire population of interest.

In this case, the population of interest would be all factory workers, and by querying every one of them (assuming it was indeed every single factory worker in Ohio), it constitutes a census, not a survey, which typically involves a representative sample.

It is not a convenience sample since that would imply a non-random selection based on ease of access, and it's not a simple random sample because not all members of the larger population (nationwide factory workers) have an equal chance of being included.

There are 65 students who walk to West Middle School each day. This is 12.5% 0f the total student at the school. How many students attend West Middle School

Answers

"This" refers to the 65 students who walk. "Is" can be written with an equal sign. 12.5% means 12.5/100 which is 0.125. "Of" in word problems means multiplication. We're trying to find the total number of students so we'll call this x.

Equation:
65=0.125x
Divide both sides by 0.125.
520=x
There are 520 students.

Answers

Answer:

Function formula P(t) = -52t +480

Step-by-step explanation:

here, P(t) denotes the number of pages to read and t represents the time in hour.

Given the statement: Shryia read a 480-page-long book cover to cover in a single session, at a constant rate. After reading for 1.5 hours, she had 402 pages left to read.

Total number of page in a long book = 480

After reading for 1.5 hours, she had 402 pages left to read.

Then,

Total number of page Shryia read in 1.5 hours is:

[tex]480-402 = 78[/tex]

Constant rate at which she is reading her book = [tex]\frac{78}{1.5} = 52[/tex] page per hour

Then, the function formula is given by:

P(t) = -52t + 480 ;  where t is in hours.

Check:

P(t) = -52t + 480

P(1.5) = -52(1.5) + 480 = -78 + 480 = 402     True.
