Answer:D

Step-by-step explanation:

This is D because your dividing by 5 or each one and thats how you get Your output number

Proportional relationship between x and y is x/y = 5. Only table D shows a proportional relationship between x and y.

A proportional relationship is a relationship between two expressions and where changes in one expression means some constant change in other expression as well. Generally it is represented as x/y = k, where x and y are two expressions and k is constant.

In order to solve this problem, first we’ll have to figure out the proportionality ratio between the x and y.

that is x/y = k (let), it should be constant.

In the table A;

first term, 3/4 = 0.75

second term, 10/6 = 1.667

Since the value of constant is not the same. Therefore the table A does not show the proportional relationship between x and y.

In the table B;

first term, 4/2 = 2

second term, 8/4 = 2

third term, 12/8 = 1.5

Since the value of constant is not the same. Therefore the table B does not show the proportional relationship between x and y.

In the table C;

first term, 12/6 = 2

second term, 14/12 = 1.667

Since the value of constant is not the same. Therefore the table B does not show the proportional relationship between x and y.

In the table D;

first term, 5/1 = 5

second term, 10/2 = 5

third term, 15/3 = 5

Since the value of constant is the same in every term. Therefore the table B shows the proportional relationship between x and y.

Therefore, proportional relationship between x and y is x/y = 5. Only table D shows a proportional relationship between x and y.

The answer is 6800 = 80m

Step-by-step explanation:

1. The best way to solve this one would be elimination

  Both the equations have the same term, 5y

  Since neither variable is isolated, it wouldn't be easy to use the method of substitution

2. Both the equations only have x or y

   SInce neither of the equations has both the variables, substitution is impossible

3. Same as 1, just that you would need to multiple one of the equations by a certain number to create equal terms to make elimination possible

4. It's perfect!!! The y is isolated and it would be simple to just substitute the first equation into the 2nd (I hope you got what I meant)

4, is the correct answer

I hope this helps!!!

Answer:

The binomial is a factor

Step-by-step explanation:

In order to show that x+3 is a factor of the polynomial, then;

f(a) = 0

Get a by equating x+3 to zero

x+3 = 0

x = -3

Get f(-3)

f(-3) =  (-3)^4 + 8(-3)^3 + 11(-3)^2 -11(-3) + 3

f(-3) = 81 - 216 + 99 + 33 + 3

f(-3) = 216-216

f(-3)  = 0

Since the remainder of the polynomial when divided by x+3 is zero, this shows that x+3 is a factor of the given polynomial

You want me to examine Jack's answer to the equation X + 5 = 10, I take it.

I can outline the broad procedures to solve this problem without knowing Jack's answer:

Add 5 to both sides of the equation to equal 10 and 5: X + 5 - 5 = 10 - 5.

Condense: X = 5.

As a result, X = 5 is the answer to the equation X + 5 = 10.

If you give me Jack's answer, I can assist you determine whether it is accurate or if there are any mistakes.

Therefore, the value of x is 5.

Answer: x = 5

Step-by-step explanation:To solve this you first need to collect the like terms 6x-2x=7+3. Add those 4x=20. After that you need to divide both sides. Then you will get you solution.

Answer:

Step-by-step explanation:

6x−13=2x+7

Inverse operation:

6x into a negative then subtract it by 2x

2x - 6x = -4

Change 7 into a negative then subtract it by -13

-13 - 7 = -20

-20 = -4x

Divide:

Answer: £23,360

Step-by-step explanation:

You can use algebra to solve this.

Assume that the original investment is x.

In the beginning of 2015 the balance had increased by 2.5% which is denoted as:

= 1.025x

Carol then withdrew a thousand:

= 1.025x - 1,000

This value then increased by 2.5% again by the beginning of 2016:

= 1.025 * (1.025x - 1,000)

Relevant expression therefore is:

1.025 *(1.025x - 1,000) = 23,517.60

1.025x - 1,000 = 23,517.60/1.025

1.025x = ‭22,944‬ + 1,000

x = 23,944/1.025

x = £23,360

Answer: g(x) = 2*x

Step-by-step explanation:

We want to find the formula of g(x) if we know that g(x - 3) = 2*x - 6

Well, the first step is to find the expression (x - 3) = y in the g(x - 3)

Then:

g(x - 3) = 2*x - 6 = 2*x - 2*3

Now we can just take the common factor 2, and write this as:

2*x -2*3 = 2*(x - 3) = 2*y

then:

g( x - 3) = g(y) = 2*y

if we just replace x by y, we get:

g(x) = 2*x

This is the formula of g(x)

Answer:

The domain of the function should be:

'x greater than or equal to negative -5'.

Hence, option A is true.

Step-by-step explanation:

Given the expression

[tex]2\sqrt{x-5}[/tex]

The domain of a function is the set of input or arguments for which the function is real and defined

We know that the value, inside the radicand, is the number found inside a radical symbol which must be greater than 0, otherwise, it would make the function undefined,

i.e.

x-5 ≥ 0

x ≥ 5

In other words, the domain of the function should be:

'x greater than or equal to negative -5'.

Therefore, the domain of the function:

x ≥ 5

[tex]\mathrm{Domain\:of\:}\:2\sqrt{x-5}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:5\:\\ \:\mathrm{Interval\:Notation:}&\:[5,\:\infty \:)\end{bmatrix}[/tex]

Hence, option A is true.

The domain of the function y = 2√(x - 5) will be x greater-than-or-equal-to 5. Then the correct option is C.

The domain means all the possible values of x and the range means all the possible values of y.

The function is given below.

y = 2√(x - 5)

Then the domain of the function will be

We know that the value inside the square root should be greater than or equal to zero. Then the domain will be

x - 5 ≥ 0

Simplify the inequality, then the domain of the function will be

x - 5 ≥ 0

x ≥ 5

The domain of the function y = 2√(x - 5) will be x greater-than-or-equal-to 5.

Then the correct option is C.

Answer:

2, 1/2

Step-by-step explanation:

Arithmetic mean of two numbers is given as

[tex]n=\frac{a+b}{2}[/tex]

Here a=x and b=1/x

[tex]n=\frac{x+1/x}{2}[/tex]

[tex]\frac{5}{4} =\frac{x^{2}+1}{2x}[/tex]

[tex]\frac{5}{2}x=x^{2} +1\\ x^{2}-\frac{5}{2}x+1=0[/tex]

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

Hence the numbers are 1/2 and 2.

If x is any real number, then the reciprocal of this number will be 1/x. For example, the reciprocal of 5 is 1 divided by 8, i.e. 1/5.

Given, one number is reciprocal to another.

So if we choose the first number to be x , the the other number becomes its reciprocal i.e. 1/x.

Now, it is given that the arithmetic mean of these two numbers is 5/4.

So using formula for arithmetic mean ,

Mean = Sum of Observations / No. of observations

[tex]\frac{5}{4} =\frac{x+\frac{1}{x}}{2} \\\frac{5*2}{4}= \frac{x^{2} +1}{x} \\\frac{5}{2} =\frac{x^{2}+1}{x} \\[/tex]

On cross Multiplication and Factorization, we get:

[tex]5x=2x^{2}+2\\2x^{2} -5x+2=0\\2x^{2} -4x-x+2=0\\2x(x-2)-1(x-2)=0\\(2x-1)(x-2)=0\\2x-1=0 , x=1/2\\x-2=0 , x=2[/tex]

So , when x=1/2 , then 1/x=2

and when x=1/2 , then x=2

Hence,  the numbers are 2 and 1/2 .
