Answer:

35 degrees

Step-by-step explanation:

Since all the angles combined equal 180 degrees, you can already subtract 55 from it and then the 90 degrees from the angle ABC. After that subtract 180-145=35

What is 10xy - 15y in factored form
Oduvanchick [21]

The factored form of 10xy - 15y is 5y(2x - 3)

<em><u>Solution:</u></em>

Given that, we have to write the given expression in factored form

<em><u>Given expression is:</u></em>

10xy - 15y

To find the factored form, let us first find the greatest common factor of 10 and 15

The factors of 10 are: 1, 2, 5, 10

The factors of 15 are: 1, 3, 5, 15

Then the greatest common factor is 5

Thus, factor out 5 from given expression

10xy - 15y = 5(2xy - 3y)

Now factor out the common term "y"

10xy - 15y = 5(2xy - 3y) = 5y(2x-3)\\\\10xy - 15y = 5y(2x-3)

Thus the factored form is found

2. Jessica's financial advisor believes that she should spend no more than 28% of her gross monthly income for housing. She has
scoray [572]

Jessica's annual salary is $68571.43.

Data;

  • percentage saved for housing = 28%
  • amount saved annually = $1600

<h3>Percentage</h3>

This is the ratio of a number to the entire value and multiplied by 100

The percentage set aside for housing is given as 28% which is $1600.

Let find 28% of x which is equal to 1600

\frac{28}{100} = \frac{1600}{x}

cross multiply both sides and solve for x

\frac{28}{100}  = \frac{1600}{x}\\ 28*x  = 100*1600\\28x = 160000\\

Divide both sides by the coefficient of x

\frac{28x}{28} = \frac{160000}{28}\\ x = 5714.28

Her monthly income is $5714.28.

Let's multiply this by 12 (months in a year) to determine her gross monthly income.

5714.28*12 = 68571.43

From the above calculations, Jessica's annual salary is $68571.43.

A) What is the domain and range of the graph? (Use the equations editor or explain)
zysi [14]

Answer:

  • domain: -5 < x ≤ 1
  • range: -3 ≤ y ≤ 1
  • is a function

Step-by-step explanation:

The domain of a relation is the set of values of the independent variable for which the function is defined. It is the horizontal extent of the graph.

The range of a relation is the set of values the dependent variable may have. It is the vertical extent of the graph.

A relation is a function if there is only one output value for any given input value. That is, a vertical line can intersect the graph in at most one place.

__

<h2>a)</h2><h3>domain</h3>

This graph extends from x > -5 to x = 1. The domain is ...

  -5 < x ≤ 1 . . . . . . . (-5, 1] in interval notation

<h3>range</h3>

This graph extends from y = -3 to y = 1. The left side of the graph does <em>not</em> include the point (-5, 1), but the right side includes the point (1, 1). So y = 1 is one of the output values of the relation. The range is ...

  -3 ≤ y ≤ 1 . . . . . . . . [-3, 1] in interval notation

__

<h2>b)</h2>

No vertical line crosses the graph in more than one place, so the relation shown is a function.

_____

<em>Additional comment</em>

Sometimes a relation is given as a table or a list of ordered pairs. If there are <em>no repeated x-values</em> (inputs), the relation <em>is a function</em>. Repeated x-(input) values usually have different output values, so violate the requirement that a function have only one output for each input.
