Answer:

y-3=7/6(x-4)

Step-by-step explanation:

the equation for point-slope form is y-y1=m(x-x1)

first let's find the slope (m)

the formula for slope is (y2-y1)/(x2-x1)

the given points: (4,3) and (-2,-4)

label the points:

x1=4

y1=3

x2=-2

y2=-4

now substitute into the equation

m=(-4-3)/(-2-4)

m=-7/-6

m=7/6

the slope is 7/6

now substitute the numbers into the equation for point-slope form

y-3=7/6(x-4)

Hope this helps :)!

Answer:

Slope and y intercept.

Step-by-step explanation:

This is necassary to write the equation of a line in y=mx+b

m is where the slope goes, and b is the y intercept.

Alternatively, you could also write the equation for a line with a point on the line and the slope.

You would then write it in point slope formula:

y-y1=m(x-x1)

This can later be converted into slope intercept form.

Answer:

When asked to write an equation, you need to know two things – slope (m) and y-intercept (b).

Or

The Standard Form for a linear equation in two variables, x, and y, is usually given as Ax + By = C where, if at all possible, A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1.

Question:

The driving distance between Manchester and London is 195 miles. Faris intends to travel from Manchester to London by coach. The coach will leave Manchester at 3:30 pm. Faris assumes that the coach will travel at an average speed of 50 mph; using his assumption workout Faris’s arrival time in London

Answer:

[tex]Arrival = 7:24pm[/tex]

Step-by-step explanation:

Given

[tex]Distance = 195\ miles[/tex]

[tex]Speed = 50mi/hr[/tex]

[tex]Take\ off = 3:30\ pm[/tex]

Required

Determine the time of arrival

First, we need to calculate the time to complete the journey.

[tex]Speed = \frac{Distance}{Time}[/tex]

Make Time the subject

[tex]Time= \frac{Distance}{Speed }[/tex]

Substitute values for Distance and Speed

[tex]Time= \frac{195mi}{50mi/hr}[/tex]

[tex]Time= 3.9hr[/tex]

The arrival time is:

[tex]Arrival = Take\ off + Time\ Taken[/tex]

[tex]Arrival = 3:30pm + 3.9\ hours[/tex]

Split

[tex]Arrival = 3:30pm + 3\ hours + 0.9\ hours[/tex]

[tex]Arrival = 6:30pm + 0.9\ hours[/tex]

Convert 0.9 hours to minutes

[tex]Arrival = 6:30pm + 0.9 * 60\ mins[/tex]

[tex]Arrival = 6:30pm + 54\ mins[/tex]

[tex]Arrival = 7:24pm[/tex]

Step-by-step explanation:

Answer:

f(x) = -5x -1

Step-by-step explanation:

For each change in x there is a -5 change in y so the slope is y = -5x

If x was 0 y would be -1 so the y-intercept is -1

Answer:

Mr. Miller's farm is 295 acres, and Mr. Newton's farm is 230 acres.

Step-by-step explanation:

From the problem we can make the following equations.....

Let "N" be the area of Mr. Newton's farm and let "M" be the area of Miller's farm. Then.....

N + M = 525

N + 65 = M

Now substitute and get....

N + M = 525

N + N + 65 = 525

2N = 460

N = 230⇒

⇒N + 65 = M

230 + 65 = 295

The equation that represents the total surface area, in square inches, of the terrarium is D. 1/2 (6)(4)+ (5X10)+2(6X10)=122

Suppose we got a triangle. Now, strech it up so as to make a stack of triangles up above another. This new 3d object is called a triangular prism.

Usually, when we talk about triangular prism, we talk about the triangular prism, whose stack goes straight up, thus, we talk about a right triangular prism.

Given that the parameters are;

Height = 4 in

Base = 6 in

Length = 10 in

Raj buys a terrarium that is in the shape of a triangular prism. he knows that every triangular prism is made up of two triangular sides and three rectangular sides.

Area of the triangular prism;

Answer:

5625in²

Step-by-step explanation:

Area of the plate = πr²

625π = πr²

625 = r²

r = √625

r = 25in

If the radius of the plate is tripled, then the new radius will be 3(25) = 75in

New Area = π(75)²

New Area = 5625π in²

If the radius is tripled, the new area of the plate is 5625in²

Answer:210ml, 140 ml, 60%

Step-by-step explanation:

Given

Juli has 200 ml of 35% hand sanitizer

Sarah has 150 ml of 85% hand sanitizer

The mixture has 60% con. i.e. 60 % is Alcohol and 40 % water

The final volume of the mixture =200+150=350 ml

Now, 60% of 350 ml= [tex]350\times 0.6=210\ ml[/tex]

So, pure Alcohol is 210 ml

Water in the final mixture= [tex]350\times 0.4=140\ ml[/tex]

The concentration of Alcohol is 60%

SOLUTION:

First, find the constant of variation k using the equation k=(x)(y)

[tex]3 = \frac{k}{ \frac{2}{3} } [/tex]

[tex]k = (3)( \frac{2}{3} )[/tex]

[tex]k = 2[/tex]

Then, find the value of y.

Answer:

$149.50

Step-by-step explanation:

Width = x

Length = 2x - 5

Perimeter of the room = 5x

Perimeter of the room = 2(length + width)

5x = 2{(2x-5) + x}

5x = 2(2x - 5 + x)

5x = 4x - 10 + 2x

5x = 6x - 10

5x - 6x = -10

-x = -10

x = 10

Width = x = 10

Length = 2x - 5

= 2*10 - 5

= 20 - 5

= 15

Perimeter of the room = 5x

= 5 × 10

= 50 square foot

If carpet costs $2.99 a square foot, what the total cost to carpet the living room

Total cost = $2.99 × 50

= $149.50
