Vicky takes 12.4 (round to 12) breaths every minute. 62 divided by 5 equals 12.4 (12)

Solve for X: 39 - 7x = -4 (7x + 7) = 4

gtnhenbr [62]

Subtract 39 from both sides

-7x = -4 - 39

Simplify -4 - 39 to -43

-7x = -43

Divide both sides by -7

x = -43/-7

Two negative make a positive

x = 43/7

For the second equation;

Simplify brackets

7x + 7 = 4

Subtract 7 from both sides

7x = 4 - 7

Simplify 4 - 7 to -3

7x = -3

Divide both sides by 7

x = -3/7

What is the other polynomial send help please

posledela

In mathematics, a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. An example of a polynomial of a single indeterminate x is x2 − 4x + 7.

Determine the domain and range of the function f(x)= 3x+2. Also, state the intervals where the function f(x)= 3x+ 2 is increasin

aev [14]

Answer:

Increasing on it's domain $(-\infty,\infty)$ because the slope is positive.

The domain and range are both all real numbers, also known as

$(-\infty,\infty)$ .

Step-by-step explanation:

All domain really means is what numbers can you plug in and you get number back from your function.

I should be able to plug in any number into 3x+2 and result in a number. There are no restrictions for x on 3x+2.

The domain is all real numbers.

In interval notation that is $(-\infty,\infty)$ .

Now the range is the set of numbers that get hit by y=3x+2.

Well y=3x+2 is a linear function that is increasing. I know it is increasing because the slope is positive 3. I wrote out the positive part because that is the item you focus on in a linear equation to determine if is increasing or decreasing.

If slope is positive, then the line is increasing.

If slope is negative, then the line is decreasing.

So y=3x+2 hits all values of y because it is increasing forever. The range is all real numbers. In interval notation that is $(-\infty,\infty)$ .
