What is the value of the expression (-8/9) divided by (-2/3) multiplied by (-4 1/2)
On a large sheet of graphing paper, Joan has drawn a picture of a castle by connecting vertex points on the grid. She decides that the picture would look better if it were reversed, changing the left side for the right side and the right side for the left. The vertex point that marks the top of the castle's flagpole is at (122, 73). If she reflected the picture across the y-axis, then what would be the new coordinates for the top of the flagpole? Type your answer as an ordered pair, like this example: (-12, 34).

Identify the domain and range of the relation. Represent the relation with amapping diagram. Is the relation a function?
{(−1, 1), (−2, 2), (4, −4), (7, −7)}

Answers

The domain and range of the relation {(-1, 1), (-2, 2), (4, -4), (7, -7)} are {-1, -2, 4, 7} and {1, 2, -4, -7} respectively.

What is relation in function?

Not every relation is a function, but every function is a relation.

A function is a relation with clear boundaries.

When we say that something is well-defined, we mean that each element has been assigned a specific image.

The given set is,

{(-1, 1), (-2, 2), (4, -4), (7, -7)}

The domain of a set is the values of x,

Domain = {-1, -2, 4, 7}

The range of a set is the values of y,

Range = {1, 2, -4, -7}

The relation makes the function because for every value of x the sign of function y is negative,

The required function is,

y = -x.

hey, im not sure if its correct or not, but here!

38 is what percent of 62?

Answers

38 = 62x
x = 38/62 = 19/31 = .6129...*100 = 61.29%

In order to find this, you divide 38/62. when you do this you get .6129. to make it a percent simply move the decimal to the right two places, giving us 61.29%. in most cases you will only need the one number after the decimal, but it depends on the question.
