For the equation, complete the given ordered pairs.

3x-y=4

{0,_} [1,_} {_,4}

Answers

3x-y = 4

so y = 4-3x = -3x +4

now you just have to remplace X by the first number given.

for 0 you have : y = -3*0 +4 = 4

so it's 0; 4

What is the value of x+y?

Answers

Answer:

x = 9

y = 3

Step-by-step explanation:

2x + 2y = 24 is the same as x + y = 12

using substitution, x = 12-y

12 - y = 3y

12 = 4y

y = 3

x = 3(3)

x = 9

The value of x + y for the given system of equations 2x+2y= 24 and x=3y will be 12.

What is the equation?

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

The equation must be constrained with some constraints.

As per the given system of equations,

2x+2y= 24

x=3y

Take common 2 from 2x+2y= 24 as

2(x + y) = 24

Divide by 2 into both sides

x + y = 12

Hence "The value of x + y for the given system of equations 2x+2y= 24 and x=3y will be 12".

What is the correct rule for y, in terms of x?

Answers

Answer:

please the question is not complete

The phrase "y is a function of x" means that the value of y depends upon the value of x, so: y can be written in terms of x (e.g. y = 3x ). If f(x) = 3x, and y is a function of x (i.e. y = f(x) ), then the value of y when x is 4 is f(4), which is found by replacing x"s by 4"s .

How is the percentage of a value calculated?

The percentage represents a value divided by 100. In this way, saying 25% of a value is the same as saying 25 out of 100, that is, 25 divided by 100. And to find the exact number of absentees in the event, just multiply the whole by the percentage

So in this case, we have the information that:

May: 223 Dinztop salesJune: 148 Dinztop sales.

Using the percentage we have:

[tex]p=\frac{148}{223} = 0.6637[/tex]

This value in percentage that will be:

[tex]0.6637*100\%= 66.37\%[/tex]

Because of the same percent rate, the amoutns sold in June:

[tex]66.37\%*148=98[/tex]

If m is an integer, then 8 x 10^m is equal to 8.

Answers

Answer:

No this is not true.

Step-by-step explanation:

An integer is a whole number and not a fraction.

An integer can be 0, 1, 3, 16, 18, 100, etc.

But an integer is either 0 - infinity.

For 8 * 10^m to equal 8, it has to be a fraction.

So, m can not be a integer. This is wrong.

Choose 1 answer:
27 <-49
-4927
Which one of the following descriptions is correct?
Choose 1 answer:
There was less rain in 2004 than in 2005.
there was less rain in 2005 than in 2004

Answers

Answer:

Both answers are the first option.

Step-by-step explanation:

Question 1: 27 is greater than -49, so that is why the first option for question one is correct.

Question 2:-49 is less than 27 so that is why 2005 had less rain compared to 2004.

The correct inequality comparison is 27 > -49.

The correct description is: There was less rain in 2005 than in 2004.

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

When we compare the relative amounts of rain in the table, we see that the amount of rain in 2005 (-49 cm) is less than the amount of rain in 2004 (27 cm).

The correct inequality comparison is: 27 > -49

The minus sign in front of 49cm in 2005 indicates that the amount of rain is less than the amount of rain in 2000.

So, the correct description is: There was less rain in 2005 than in 2004.
