Answer:

the coefficient of x is 2/3 which is the constant.

Answer:

ans: x= 11/4 and y= 11/8

Step-by-step explanation:

4x=6y=6 mean

4x= 6 and 6y= 6 so, 6-6=0 i.e

4x - 6y = 0 say equation ....1

and given

2x + 5y = 11 say equation ....2

to solve by eliminating methods,

multiply equation....2 by 2 and subtract from ....1

i.e

4x - 6y =0

4x + 10y= 22

(-) (-) (-)

0+ (-)16y = - 22

y = -22/-16

y = 11/ 8

to get , x put y in either equation 1 or 2

I.e x= 11/4

this value of x and y satisfy both equations

Answer:

(x-a)(y-b)=r²

(x-(-3))(y-(-5))=r²

(x+3)2(y+5)2=36

Answer:

D. -10000

Step-by-step explanation:

you really need to copy or type the question better.

I can only assume what you really mean.

I guess, you want to say that F(x) = 1/(x+1)

when the value for x gets close to -1, the whole expression gets close to 1/0, which would bring numbers with larger and larger absolute values, leading to infinity.

you also did not say from what direction we are getting closer to -1.

we could come from -2 and move closer and closer to -1.

in this case (x+1) would always be smaller than 0 (negative sign).

or we could come from +1 and then 0 and move towards -1, in which case (x+1) would airways be bigger than 0 (positive sign).

anyway, when being closer and closer to -1, the absolute value of the resulting functional values will get bigger and bigger.

the only answer option with a larger absolute value is D (-10000).

so, that had to be the solution, and it also means that we are coming from -2 to -1, and the sign is negative.

Answer:

[tex]a_{n}[/tex] = - [tex]\frac{1}{4}[/tex] [tex]a_{n-1}[/tex]

Step-by-step explanation:

The recursive formula lets us find a term in the sequence by multiplying the previous term by the common ratio r

Here r = [tex]\frac{20}{-80}[/tex] = [tex]\frac{-5}{20}[/tex] = - [tex]\frac{1}{4}[/tex]

Then recursive formula is

[tex]a_{n}[/tex] = - [tex]\frac{1}{4}[/tex] [tex]a_{n-1}[/tex]

Answer:

x(3x+14)

Step-by-step explanation:

what do those terms share? they share the letter "x"

therefore we multiply x by 3x^2/x + 14x/x

3x^2/x = 3x and 14x/x = 14

Answer:

83 racoons

Step-by-step explanation:

18+67- 2

you would subtract the two they found with tags

Answer:

just look at the constant terms...

A: 5

B: 7

C: -5

1) 11-6 = 5 thus answer A

2) -3 -2 = -5 thus answer C

3) -5 - (12) = -5 + 12 = 7 thus answer B

Step-by-step explanation:

Answer:

Although this makes for a lot of potential fun with formulas, mind experiments and arguments, the answer is plain.

Infinity is already everything so there is no more to it, infinity plus infinity would be still just infinity, which is btw infinite.

Answer:

infinity + infinity =  infinity

Answer:

For any integer number n, the inverse additive of n is also an integer K such that:

n + K = 0

solving this for K, we get that:

K = -n

Then the inverse additive of n is -n.

Now that we know this let's complete this.

We know that for any two integers A and B, a minus b is equal to a plus the additive inverse of b.

To check this:

a minus b is written as:

a - b

And a plus the additive inverse of b is:

a + (-b)

because -b is the additive inverse of b.

Remember the rule sign:

(+)*(-) = -

Then we can rewrite:

a + (-b) = a - b

Then the statement is true.

"For any two integers a and b, a minus b is equal to a plus additive inverse of b is equal to a + (-b)"

Answer:

The last number line or D.

Step-by-step explanation:

To find the remaining coats to be collected, subtract the coats that are collected from the total of coats needed.

So:

78 - 13= 65

They must collect a total of 65 and more to break the last year's record of 78 coats. Number line D, represents the solution of this inequality.

Hope this helps! Have a nice dayy! :)

Answer:

inverse: f-(x)=x+3/5

Step-by-step explanation:

Set f(x)=x and x=y

x=y-3/5

isolate y by adding 3/5 to both sides

x+3/5=y

this is the inverse :)

Answer:

2

Step-by-step explanation:

let the number be n , then

7n - 8 = 6 ( add 8 to both sides )

7n = 14 ( divide both sides by 7 )

n = 2

The number is 2

In other words, the number 4 goes in the green box.

Explanation:

2 yellow + 3 pink + 5 blue = 10 total marbles

We have 5 blue out of 10 total, so 5/10 = 1/2 represents the probability of picking a blue marble.

Picking two marbles in a row is represented by the probability (1/2)*(1/2) = 1/4

The fraction 1/2 stays the same for both selections because we put the first marble back.

Answer:

C = 12π or 37.7

Step-by-step explanation:

A = πr²

36π = πr²

π's get divided out and you are left with:

r² = 36

if you take the square root of 'r' it will equal the square root of 36, which is 6

C = 2πr

C = 2π(6)

C = 12π or 37.7

Answer

the answer is 12*sqrt pi

Answer:

Table N 4

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=ky/x=k or y=kxy=kx

Verify the table 4

For x=1, y=2

so

y/x=2/1=2

For x=2, y=4

so

y/x=4/2=2

For x=3, y=6

so

y/x=6/3=2

therefore

The constant of proportionality k is equal to 2 and the equation is equal to

y=2x

The table 4 represent a direct variation, therefore is a possible ratio table for ingredients X and Y

Answer:

Step-by-step explanation:

First find the first radius

c=88cm

=2*22/7*r=88cm

=r=14cm

22/7 (pie as common)(R1^2+R2^2=637cm)

14^2+R2^2=637cm

196+R2^2=637cm

R2^2=637-196=441

R2=√441

R2=21

first radius =14cm

second radius  =21cm

Answer:

3(y+7)=2

Step-by-step explanation:

Answer: y = 6x

Step-by-step explanation:

Since this is a direct proportion, we will introduce the constant of proportionality here and this will be:

y = kx

Since y = 30 and x= 5,

30 = 5 × k

30 = 5k

k = 30/5

k = 6

Therefore, the equation that connects y to x will be:

y = kx

y = 6x

The equation that connects y to x is y = 6x.
