Answer:

The answer is:

y =  x/x  −2

What Is The Inverse Function Of F(x) = X/x-2
Answer 2

Answer:[tex]f^{1}=\frac{2x}{x-1}[/tex]

Step-by-step explanation:

Write f(x) =x/x-2 as an equation

[tex]f(x)=\frac{x}{x-2}[/tex]

Interchange the variables

[tex]x=\frac{y}{y-2}[/tex]

solve for y, multiply equation by y-2.

[tex]y=\frac{2x}{x-1}\\[/tex]

replace y with [tex]f^{1}[/tex](x)

you get the above answer.

your answer.

She is given a $100 gift to start and saves

after 1 month, Jane has saved $135.Does it make sense to represent the relationship between the amount saved

ne constant rate? Why or why not? Explain.

Answers

Answer:

Yes

Step-by-step explanation:

Since it is mentioned that Jane saved $35 in a month from her allowance  also the starting amount is $100 and she saved $135 after month

So based on the above information, yes it makes the sense as it represents the relation between the saving amount and number of months considering one constant rate as it she saves the similar money amount for every month

If (1,-1) is a point on the line 2x-(2a+5)y=5 then find the value of a​

Answers

Answer:

a = - 1

Step-by-step explanation:

Since ( 1 , -1) is a point on the line 2x-(2a+5)y=5 we can substitute it into the equation to find a

We have

2(1) - (-1)(2a + 5) = 5

Multiplying two negatives make a positive

That's

2 + 2a + 5 = 5

2a + 7 = 5

Group like terms

Send the constants to the right side of the equation

That's

2a = 5 - 7

2a = - 2

Divide both sides by 2

That's

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

We have the final answer as

a = - 1

This year,a farm planted 400,000corn stalks.Last year,the farm planted 275,650cornstalks. How many more cornstalks did the farm plants this year than last year?

Answers

Answer:

The farm planted 124,350 more cornstalks

Step-by-step explanation:

Here in this question, we want to know how much more corn stalks did a farm plant this year compared to last year.

Let’s picture it this way;

Possibly due to expansion purposes, the farm planted more cornstalks this year than last year. So to find the difference in the cornstalks planter between the two years, what needs to be done is simply to subtract the number of corn stalks planted last year from the number of corn stalks planted this year.

From the question, the number of cornstalks planted last year was 275,650 while the number of cornstalks planted this year was 400,000; So the difference between the two will be ;

400,000 - 275,650 = 124,350 cornstalks

Solve for x: the quantity of x plus 20 over 2 = 3x

Answers

Answer:

x = 4

Step-by-step explanation:

For this problem, we simply need to convert the words into the left hand side of the equation and solve for x:

The quantity of implies a grouping

x plus 20 is the quantity

And we want the quantity over 2 all equal to 3x:

( x + 20 ) / 2  = 3x

( x + 20 )  = 6x

20 = 5x

4 = x

And now we can check to see if x is correct by plugging back into the equation:

( x + 20 ) / 2 = 3x

( (4) + 20 ) / 2 ?= 3(4)

( 24 ) / 2 ?= 12

12 == 12

Therefore, we have shown the value of x to be equal to 4.

Cheers.

Answer:

x+20/2=3x.

6x=x+20.

6x-x=20.

5x=20.

x=4.


Q1. Helen can collect 240 flowers in 20 minutes. How many flowers can
she collect in 35 minutes?​

Answers

Answer:

420 flowers

Step-by-step explanation:

20 minutes = 240 flowers

1 minute =240/20 flowers

35 minutes = (240*35)/20 flowers

          The answer is 420 flowers.

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━  

Helen can collect 240 flowers in 20 minutes.

You need to find the number of flowers she can collect in 35 minutes.

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━  

1: Find the unit rate of Helen collecting flowers. To find the unit rate, just divide 240 by 20, to see how many flowers she can collect per minute.

2: Multiply the number of flowers Helen can collect in 1 minute by 35 (since 1 times 35 is 35).

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━  

1: 240 divided by 20 is 12. Helen can collect 12 flowers per minute. The unit rate of Helen collecting flowers is 12 flowers per minute.

2: Since Helen can collect 12 flowers per minute, you need to find out how many she can collect in 35 minutes. To get from 1 minute to 35 minutes, you multiply 1 by 35. So you need to multiply 12 by 35 as well. 12 times 35 is 420. So Helen can collect 420 flowers in 35 minutes.

Step-by-step explanation:

Coordinates of A,B,C and D are,

A(2, 4), B(4, 4), C(3, 2) and D(1, 2)

Rule for the reflection over a line y = x,

(x, y) → (y, x)

Therefore, new image of ABCD will be,

A(2, 4) → A'(4, 2)

B(4, 4) → B'(4, 4)

C(3, 2) → C'(2, 3)

D(1, 2) → D'(2, 1)

Rule for translation [tex]T_{-1, -2}[/tex],

(x, y) → (x - 1, y - 2)

By this rule image of A'B'C'D' will be,

A'(4, 2) → A"(3, 0)

B'(4, 4) → B"(3, 2)

C'(2, 3) → C"(1, 1)

D'(2, 1) → D"(1, -1)

the hypothenus of a right angle triangle is 13cm. if one other side of the triangle is 1cm shorter than the hypothenus, calculate the third side of the triangle

Answers

Answer:

5 cm.

Step-by-step explanation:

Let the lengths of the other 2 sides be 13-1 = 12  and x cm.

Then by Pythagoras:

13^2 = 12^2 + x^2

x^2 = 13^2 - 12^2

x^2 = 169 - 144 = 25

x = √25

x = 5 cm.

Step-by-step explanation:

Hey, there!!

As per your question,

There is a Right angled triangle, whose hypotenuse is 13 cm, one side is (13-1)=12 cm.

another side = ?

Let ABC be a Right angled triangle, taking angle "theta" as a refrence angle.

Hypotenuse (h)= 13 cm.

base ( b) = x

perpendicular (p)= 12cm.

By Pythagoras relation we get,

[tex]b = \sqrt{ {h}^{2} - {p}^{2} } [/tex]

[tex]b = \sqrt{ {13}^{2} - {12}^{2} } [/tex]

[tex]b = \sqrt{169 - 144} [/tex]

Therefore, base is 5 cm. Or the third side is 5 cm.
