Considering the expression of a line, the equation of the line that passes through the pair of points (-66) and (3,-2) is 8/9x +y= 2/3.

Linear equation

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope m of said line can be calculated using:

m= (y₂ - y₁)÷ (x₂ - x₁)

Substituting the value of the slope m and the value of one of the points in the expression y = mx + b, the value of the ordinate to the origin b can be obtained.

The standard form of the line is Ax +By= C

Equation in this case

In this case, being (x₁, y₁)= (-6, 6) and (x₂, y₂)= (3, -2), the slope can be calculated as:

m= (-2 - 6)÷ (3 - (-6))

m= (-2 - 6)÷ (3 + 6)

m= (-8)÷ 9

m= -8/9

Considering point 2 and the slope, you obtain:

-2= (-8/9)×3 + b

-2= -8/3 + b

-2 +8/3= b

2/3= b

The equation of the line is y= -8/9x +2/3.

Finally, the standard form of the line is 8/9x +y= 2/3

Answer:

[tex]f(t)=43,200-7200t[/tex]

Step-by-step explanation:                      

We have been given that a delivery company purchased a new delivery truck for $43,200. The depreciated value of the truck can be estimated by the number of t years in service. The truck depreciates at a rate of $7,200 per year.

This means that after t years truck will depreciate 7200t. To find the truck's depreciated value after t years we will subtract 7200t from the cost of new delivery truck (43,200).  

[tex]f(t)=43,200-7200t[/tex]          

Therefore, the function [tex]f(t)=43,200-7200t[/tex] could be used to estimate the truck's depreciated value after t years.

The depreciated value of the truck after t years can be estimated by the linear function ƒ(t) = 43200 - 7200t, reflecting a straight-line depreciation method at a rate of $7,200 per year.

To estimate the depreciated value of the delivery truck after t years, we can use a linear equation which reflects a straight-line depreciation method. Since the truck cost $43,200 and depreciates at a rate of $7,200 per year, the equation representing the depreciated value of the truck after t years would be ƒ(t) = 43200 - 7200t. This equation starts with the initial value of the truck and subtracts the depreciation cost multiplied by the number of years the truck has been in service.

Depreciation is a way businesses can allocate the cost of a physical asset over its useful life. In this case, each year the truck is in service, it loses $7,200 in value. After one year, the value of the truck would be $43,200 - $7,200, which equals $36,000, and you would continue to subtract $7,200 for each additional year to determine the truck's value at any given time.

The shaded region, which is approximately 251.74 cm².

For the area of the shaded region, we need to calculate the area of a trapezium and the area of two semicircles.

Given data: AB = 28 cm , DC = 12cm and h = 14 cm

The formula for the Area of Trapezium:
Area of trapezium = 1/2 × (AB + DC) × h
Substituting the given values:
Area of trapezium = 1/2 × (28 + 12) × 14 = 280 cm²

The formula for the Area of a Semicircle:
Area of semicircle = πr²/2
Given that the radius r is 3 cm:
Area of two semicircles = 2 × π × 3²/2 = 28.26 cm²

Area of the Shaded Region:
Area of shaded region = Area of trapezium - Area of two semicircles
Area of shaded region = 280 - 28.26 ≈ 251.74 cm²

Therefore, the area of the shaded region is approximately 251.74 cm².

Answer:

$ 25.31 finance charges  he can save by making the purchase on the last day of the billing cycle versus the first day of the billing cycle

Step-by-step explanation:

In the beginning of Month ,  ADB will be on the total amount of balance and the purchase that means ADB = 0.21 (2360 + 1500)/12

= $ 67.55

ADB at the end of the month  

Part of 2360 for 27 days = (2360 x 27)/28 = $ 2275.71

Part of 3860 for 1 day = (3860 x 1)/28 = $ 137.85

So the total becomes $ 2275.71 + $ 137.85 = $ 2413.56

So , ADB will be $ 2413.56 x (0.21)/12

= $ 42.23  

Difference in the finance charges at the beginning and at the end of the month is  

$ 67.55 - $ 42.23

Answer:

1350

Step-by-step explanation:

We can write a proportion to find the total amount in the school this year using the information given. A proportion is two equivalent ratios set equal to each other. If 10% has decreased, then 90% is now left.

[tex]\frac{10}{100}=\frac{y}{1500}[/tex]

We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.

10(1500)=100(y)

15000=100y

y=150

Y is the number of students who are now gone. We subtract 1500-150=1350

6 hours

The two hoses together take 1/3 the time (4/12 = 1/3), so the two hoses together are equivalent to 3 of the first hose.

That is, the second hose is equivalent to 2 of the first hose. Two of the first hose could fill the vat in half the time one of them can, so 6 hours.

The second hose alone can fill the vat in 6 hours.

_____

The first hose's rate of doing work is ...

... (1 vat)/(12 hours) = (1/12) vat/hour

If h is the second hose's rate of doing work, then working together their rate is ...

... (1/12 vat/hour) + h = (1/4 vat/hour)

... h = (1/4 - 1/12) vat/hour = (3/12 -1/12) vat/hour = 2/12 vat/hour

... h = 1/6 vat/hour

so will take 6 hours to fill 1 vat.

The second hose can fill the vat alone in 6 hours, calculated by subtracting the work rate of the first hose from their combined work rate.

The question is about the time it would take for the second hose to fill the large vat alone, given that the first hose takes 12 hours alone, but together they take 4 hours. We are not given any info about the hose size or flow rate, so those don't need to be involved here.

We can analyze this problem in terms of work done. We know that one hose can fill the vat in 12 hours, so its work rate is 1/12 of the vat per hour. When we add the second hose, the vat is filled in 4 hours. The combined work rate of both hoses is 1/4 of the vat per hour.

To find the work rate for the second hose, we subtract the work rate of the first hose from the combined work rate: 1/4 - 1/12 = 1/6. This means the second hose can fill the vat in 6 hours alone.

Step-by-step explanation:

The equation of inverse variation is

y = k/x,

where k is a constant.

We can use the given x- and y-coordinates to find k.

y = k/x

15 = k/11

k = 165

The inverse variation equation for this problem is

y = 165/x

For y = 3,

3 = 165/x

3x = 165

x = 55

Answer:

C

Step-by-step explanation:

given x varies inversely as y then the equation relating them is

x = [tex]\frac{k}{y}[/tex] ← k is the constant of variation

To find k use the given condition x = 11 when y = 15

k = xy = 11 × 15 = 165 , hence

x = [tex]\frac{165}{y}[/tex] ← inverse variation equation

when y = 3, then

x = [tex]\frac{165}{3}[/tex] - 55 → C

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

The number of new houses = 3

The number of old houses = 7

So , the ratio of old houses to new houses = number of old houses : number of new houses

Substituting the values in the equation , we get

Ratio of old houses to new houses = 7 : 3

Now , the number of new houses = 15

So , the number of old houses A is given by the proportion equation ,

7 : 3 : : A : 15

On simplifying the equation , we get

7/3 = A / 15

Multiply by 15 on both sides of the equation , we get

A = ( 7 x 15 ) / 3

A = 7 x 5

A = 35 houses

Final answer:

The correct number of old houses is found by determining how many times the 3:7 ratio of new to old houses fits into the 15 new houses and then applying that to the 7 old houses in the ratio, which results in 35 old houses.

Explanation:

The question asks to find the number of old houses in a city given the ratio of new to old houses and the number of new houses. There is a ratio of 3 new houses for every 7 old houses. If there are 15 new houses, we need to find how many times the ratio fits into the number of new houses and then apply that same multiplier to the number of old houses.

To find this, we divide the number of new houses by the number of new houses in the ratio:

Number of times the ratio fits = 15 new houses ÷ 3 new houses per ratio = 5 times

Now, we multiply the number of old houses in the ratio by 5:

Number of old houses = 7 old houses per ratio × 5 times = 35 old houses

Therefore, the correct answer is B. 35.

This question is using positive and negative integers to represent elevation and descending.  The surface of the pool would represent an elevation of 0, where we are level.  However, when Carlos descends (swims to the bottom) of the pool, he is at an elevation of -12 because he is below the surface.  The opposite of -12 would be +12.  So the opposite of where Carlos is -12ft below the surface of the water would be +12 foot above the surface of the water.  

Answer:

the only point is (0,1) if u would look at the graph i post

Step-by-step explanation:

The point which lies on the graph of f(x) = (1/3)x will satisfy the function thus point (-1, -1/3) will lie on the graph thus option (D) is correct.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

As per the given function,

f(x) = (1/3)x

Substitute, x = 0,

y = f(0) = (1/3)0 = 0

So,(0,1) will not lie on the graph.

Similarly, (3, 27) and (−2, 9) also do not lie on the graph.

Substitute (-1,-1/3)

-1/3 = (1/3)(-1) = -1/3

Thus, it will be the point of the function.

Hence "The point which lies on the graph of f(x) = (1/3)x will satisfy the function thus point (-1, -1/3) will lie on the graph".
