You need to have variables one one side and constants on the other. ax - ax + by = c - ax by = c - ax by/b = (c - ax)/b y = (c - ax)/b

You said . . . . . ax + by = c

Subtract ' ax ' from each side . . . by = c - ax

Divide each side by ' b ' . . . y = (c - ax) / b

Given fraction is
$f(x) = \frac{x^2 + 4x + 3}{x^2 - 9}$

As we know fraction is not defined where denominator is equal to zero.

So let's find where denominator is zero.

$x^2 - 9 = 0$

We can factorize it as $a^2 - b^2 = (a+b)(a - b)$

So we can write given equation as

$(x+3)(x-3) = 0$

So x = 3 or x = -3.

So function is undefined at x = 3 and x = -3.

So option 3 is correct.

Classify the real number. (Choose all that apply). –9 A.) Rational B.) Whole C.) Irrational D.) Natural E.) Integer

IRISSAK [1]

Whole numbers are the numbers 0, 1, 2, 3, 4 and so on and negative numbers are not considered whole numbers.

natural numbers are called the counting numbers that are the numbers 1, 2, 3, 4, and so on. they are positive numbers and zero is not considered a natural number as you can see.

integers are all the whole numbers and their opposite (negative) but negative numbers are NOT whole or natural numbers. fractions and decimals are not integers.

rational numbers are numbers that include all the integers, plus all fractions, or terminating decimals and repeating decimals.

irrational numbers are an infinite number of digits to the right of the decimal point, without repeating.

so your answer is integer and rational, hope this helped! :)

A yo-yo factory has fixed operating costs of $5000 per day plus costs of $2 per yo-yo produced. If a yo-yo sells for $5.50, what

Jlenok [28]

Answer:

1429

Step-by-step explanation:

Break even is expressed as:

5000+2x = 5.5x

5000=5.5x-2x

5000=3.5x

$\frac{5000}{3.5} = \frac{3.5x}{3.5}$

1428.57=x

Since you cannot sell a fractional yo-yo, round up to 1429
