Does the table show a proportional relationship, if so , what is the value of y when x is 10

Answers

the table does show a proportional relationship, and the value of Y when X is 10 would be 3 1/3.

Yes, the given table shows a proportional relation with constant of proportionality  1/3.

What are proportional relation?

Two variables x and y are in proportional relation if the relation between  then is in the form y = k x, where k is the constant of proportionality.

Or we can say for all pairs ( x, y ) , y/x = k , k is constant then the table containing (x, y) values shows a proportional relationship.

From given table

When x= 5 , y =[tex]1\frac{2}{3}[/tex] =5/3

Then, y/x = (5/3)/5 = 1/3 =k

When x =6 , y =2

Then, y/x = 2/6 = 1/3 =k

When  x =  7 , y = [tex]2\frac{1}{3}[/tex] = 7/3

Then, y/x = (7/3) /7 = 1/3 =k

When x=8 , y =[tex]2\frac{2}{3}[/tex] = 8/3

Then , y/x = (8/3) / 8  = 1/3 =k

Thus for each pair (x, y) given in the table the ratio y/x is same , this ratio is say k = 1/3

Therefore, for the given table y/ x = k or y =k x with k = 1/3 , and the table  shows a proportional relation with constant of proportionality  1/3.

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

The given, ratios are:

4/5 km : 5 minutes

[tex]3\frac{1}{10}[/tex] km: 3/10 minutes

1 kilometer: 1/5 minutes

1/3 kilometer: [tex]1\frac{2}{3}[/tex] minutes

[tex]4\frac{1}{2}[/tex] kilometer: 2 minutes

[tex]6\frac{1}{4}[/tex] kilometer:  [tex]1\frac{1}{4}[/tex] minutes

We need to check which ratios have 5 as unit rate.

[tex]6\frac{1}{4}[/tex] kilometer:  [tex]1\frac{1}{4}[/tex] minutes has unit rate as 5

If solving a system of linear equations by elimination or substitution I get that 2=3, it means (check all that apply)

If the system of equations is 2 linear equations in 2 variables, there is infinity number of solutions
If the system of equations is 3 linear equations in 3 variables, there is infinity number of solutions
If the system of equations is 2 linear equations in 2 variables, the system has no solutions
If the system of equations is 3 linear equations in 3 variables, the system has no solutions

Answers

Answer:

If I get 2=3 in solving the system, it means the following:

If the system of equations is 2 linear equations in 2 variables, the system has no solutions If the system of equations is 3 linear equations in 3 variables, the system has no solutions

Step-by-step explanation:

The solution of linear system of equations implies that a point has to be found that holds true on all equations involved.

The system may consist of two equations involving two unknowns or may consist of three equation with three unknowns.

When a system of equation has no solution, the variables are removed in solving the equations and we get an equation or values in the form.

constant = constant

So,

If I get 2=3 in solving the system, it means the following:

If the system of equations is 2 linear equations in 2 variables, the system has no solutions If the system of equations is 3 linear equations in 3 variables, the system has no solutions

El orden de forma creciente de los números enteros es:

-32< -21< -16< -11< -7< -2< < 6< 20< 30< 32

Step-by-step explanation:

Ordenar de forma creciente números enteros implica ordenarlos de menor a mayor. Esto es, debes considerar primero el número que posea el menor valor y luego ir ordenándolos a medida que su valor vaya aumentando, para dejar en último lugar al que posea el mayor valor.

Para ordenarlos debes tener en cuenta que:

todo número negativo es menor que cero, mientras que todo número positivo es mayor que cero. de dos enteros negativos es mayor el que tiene menor valor absoluto. de los enteros positivos, es mayor el que tiene mayor valor absoluto.

Entonces, en este caso el orden de forma creciente de los números enteros es:

-32< -21< -16< -11< -7< -2< < 6< 20< 30< 32

Answers

Answer:

There are no values of

that make the equation true.

No solution

Step-by-step explanation:

-x + 5 + 6x = 1 + 5x + 3

Group like terms

-x+6x+5=1+5x+3

Add similar elements:-x+6x=5x

5x+5=1+5x+3

Group like terms

5x+5=5x+1+3

Add the numbers 1+3=4

5x+5=5x+4

Subtract 5 from both sides

5x+5-5=5x+4-5

Simplify

5x=5x-1

Subtract 5x from both sides

5x-5x=5x-1-5x

Simplify

0=-1

  A = 560 +32x

The width of the parking lot extension is (52 -20 -24) = 8 yards, so its area is ...

  extension area = 8P

We want the extension area to be equal to the original area so that adding the extension will double the area:

  extension area = A

  8P = 560 +32x

  P = 70 +4x . . . . . . divide by 8
