Which expressions represent a quadratic expression in factored form?

Bingel [31]

Answer:

3 and 4

Step-by-step explanation:

Well to start we have to know that they are asking us, a factorized form of a quadratic expression

a quadratic expression is of the form

ax ^ 2 + bx + c

Now the factored form is as follows

a ( x - x1 ) ( x - x2 )

Next, let's look at each of the options

In this case we lack a term with x since if we solve we have a linear equation

1. 5(x+9)

5x + 45

In this case if we pay attention they are being subtracted instead of multiplying, so we will not get a quadratic function

2. (x+4) - (x+6)

-2

In this case we have everything we need, now let's try to solve

3. (x-1) (x-1)

x^2 - x - x + 1

x^2 - 2x + 1 quadratic function

In this case we have everything we need, now let's try to solve

4. (x-3) (x+2)

x^2 -3x +2x -6

x^2 -x - 6 quadratic function

In this case we have a quadratic function but we do not have it in its factored form since we can observe the x ^ 2

5. x^2 + 8x

A worker is paid $2,350 monthly and has $468 withheld from each monthly paycheck. Which of the following is her annual net salar

kirill115 [55]

Answer:

Annual net salary = $22,584

Step-by-step explanation:

Given:

Monthly wage = $2,350

Withheld paycheck = $468

Find:

Annual net salary = ?

Computation:

Total net salary = Monthly wage - Withheld paycheck

Total net salary = $2,350 - $468

Total net salary = $1,882

Annual net salary = Total net salary × 12

Annual net salary = $1,882 × 12

Annual net salary = $22,584

Find the equation of a line with the given points. (Put your answers in the form y = mx + b.) (7, 3) (3, 7)

igor_vitrenko [27]

By "inspection" you can write the equation as
.. x + y = 10
Then
.. y = -x +10 . . . . . . . . the desired form

Explain how the words term and coefficient are used in talking about the algebraic expression.

cupoosta [38]

<h2>Answer:</h2>

The algebraic expressions are composed of several elements: Terms, Coefficients, Signs, Variables and Exponents. In this case we will focus on the first two.

The terms are composed of sign, coefficient, variable and exponent. The terms are separated from each other by the plus sign (+) or the minus sign (-).

For example, in the following expression:

2x-3x

We have two terms separated by the negative sign (-):

2x is the first term

-3x is the second term

Now, the coefficients are the numbers that multiply the variable. Note that if this coefficient is one (1) it is omitted .

For example in the following expression, the variable is x:

2x-3x+x

2 is the coefficient of x in the first term

-3 is the coefficient of x in the second term

1 is the coefficient of x in the third term, but is omitted

In order to understand this in a better way, see the figure attached, where the algebraic expression is composed by one term.
