Which of the tables represents a function? (4 points)
Please help i’m having a really hard time

Answer:

2x +  y = 11

a² + b = 9

Step-by-step explanation:

I solved these by using order of operations and subsitution.

m₁ = 10/3

m₂ = 1/2

6m² - 23m + 10 = 0​

6m² - 2m - 20m + 10 = 0

3m(2m - 1) - 10(2m - 1) = 0

(3m - 10)(2m - 1) = 0

3m - 10 = 0 =>3m = 10 => m₁ = 10/3

2m - 1 = 0 => 2m = 1 => m₂ = 1/2

Answer:

(a). y = 5

(b). RS = 28

     ST = 19

     RT = 47

Step-by-step explanation:

(a). There are three points R, S and T on a number line.

Therefore, RT = RS + ST -------(1)

Since, RT = 10y - 3

RS = 5y + 3

ST = 3y + 4

By substituting these values in the equation (1)

10y - 3 = (5y + 3) + (3y + 4)

10y - 3 = 8y + 7

10y - 8y = 7 + 3

2y = 10

y = 5

(b). RS =  5y + 3

           = 25 + 3

           = 28

      ST = 3y + 4

           = 15 + 4

           = 19

      RT = 10y - 3

            = 50 -3

            = 47  

Answer and Step-by-step explanation: Midpoint is the middle point in a segment line, i.e., it is at the center of a segment line.

On a baseball field, distance between home plate and second base is 127.28ft. The midpoint will be:

midpoint = [tex]\frac{127.28}{2}[/tex]

midpoint = 63.64ft

To be the midpoint, pitcher's mount must be 63.64ft away from the home plate. Since it's less than that, pitcher's mount is not the midpoint between home plate and second base.

Answer:

TC = 36t + 25

Step-by-step explanation:

The amount paid by Carla as a storage fee or fixed cost = $25

Monthly rent or variable cost = $36

Let the number of months = t

Now we have to find the expression that represents the total cost. Below is the formula to find the expression.

Total cost = Variable cost + Fixed cost

Total cost = 36t + 25

TC = 36t + 25

Answer:

B. The absolute value parent function

Step-by-step explanation:

[tex]f(x)=|x|[/tex]

Referred to as absolute value, the value inside the bars is measured in terms of its distance from 0. Therefore:

[tex]|0|=0\\|3|=3\\|-3|=3[/tex]

In essence, a negative value within the bars becomes positive, while a positive value remains positive.

Lets assume someone works 10 hours a day for 5 days a week.

Weekly total:

10 * 7.15 = $71.50 per day

71.5 * 5 = $357.50 per week

There are 52 weeks in a year so we can multiply.

357.50 * 52 = $18,590 per year

This is how you can solve this problem if you are given these details.

n = -8

Answer: A) a number is negative

Step-by-step explanation:

A conditional statement is written as:

If P, then Q.

Where P is the hypothesis and Q the conclusion.

In this case, we have:

If a number is negative, then the number is less than zero.

then we have:

P = a number is negative.

Q = the number is less than zero.

Then the hypothesis will be "a number is negative"

The correct option is A.

Answer:

number is negative

Step-by-step explanation:

Steps to solve:

4x + 6 = 10 - 4

~Simplify

4x + 6 = 6

~Subtract 6 to both sides

4x = 0

~Divide 4 to both sides

x = 0

Best of Luck!

Answer:

[tex]\large\boxed{x = 0}[/tex]

Step-by-step explanation:

4x + 6 = 10 - 4

Subtract 10 - 4

4x + 6 = 6

Subtract 6 from both sides of the equation

4x = 0

Divide both sides of the equation by 4

[tex]\large\boxed{x = 0}[/tex]

Answer:

[tex]s = \sqrt{2a} [/tex]

Step-by-step explanation:

A = 0.5S^2

2A = S^2

Therefore,

[tex]s = \sqrt{2a} [/tex]

To express the length in terms of the area, is an illustration of change of subject of formula.

The equation that express S in terms of the area is: [tex]S =\sqrt{2A}[/tex]

Given that:

[tex]A = \frac 12S^2[/tex]

First, multiply both sides by 2

[tex]2 \times A = \frac 12S^2 \times 2[/tex]

[tex]2 \times A = S^2[/tex]

[tex]2A = S^2[/tex]

Take positive square roots of both sides

[tex]\sqrt{2A} = \sqrt{S^2[/tex]

[tex]\sqrt{2A} = S[/tex]

Rewrite the equation as:

[tex]S =\sqrt{2A}[/tex]

Hence, the equation that express S in terms of the area is: [tex]S =\sqrt{2A}[/tex]

Step-by-step explits its C.130%anation:

Answer:

La opción correcta es;

d) R $ 1.200,00

Step-by-step explanation:

El monto que Joao prestó a José = R $ 1.000,00

La duración del préstamo = 6 meses

El plazo de interés del préstamo = interés simple del 10% por trimestre

La cantidad que José tiene que pagarle a Joao después de 6 meses viene dada por la siguiente fórmula de interés simple;

A = P · (1 + r · t)

A = La cantidad que José tiene que pagarle a Joao después de 6 meses

P = La cantidad que Joao prestó a José = R $ 1.000,00

r = La tasa de interés = 10% / trimestre = 10% / (3 meses) = 0.1 / (3 meses)

t = La duración del préstamo = 6 meses

Por lo tanto, al sustituir los valores anteriores en la fórmula de interés simple, tenemos;

A = R $ 1.000,00 × (1 + 0,1 / (3 meses) × 6 meses) = R $ 1.000,00 + R $ 200,00 = $$ 1.200,00

El monto que José debe pagar a Joao después de 6 meses = R $ 1.200,00
