Phoenix [80]3 years ago

We must follow order of operations rules (PEMDAS) here: exponentiation first, followed by multiplication and division, followed by addition and subtraction.

Thus, -2^2-3(-2)+1 becomes:

-[4] + 6 + 1 = 2 + 1 = 3 (answer)

Use synthetic division to find the result when 3x^3 + 13x^2 + x – 12 is divided by<br> X + 4.
IgorC [24]

Answer:

3x² + x - 3

Step-by-step explanation:

The way I like to do it is to get rid of the x's and just use the numbers in the case of synthetic division

Pretend the square root of the division symbol

-4 √ 3 12 1 -12

Quick note: We're dividing by -4 because we're dividing by x + 4

First bring down the 3

-4 √ 3 13 1 -12

      3

Multiply it by 4 then bring add it to the next number

-4 √ 3 13 1 -12

          -12

       3   1

Add that number to the next one

-4 √ 3 13 1 -12

        -12 -4

      3    1   -3

Finally repeat the step for the last number

-4 √ 3 13 1 -12

       3 -12 -4 +12

       3    1   -3   0

Now take those bottom numbers and add back the x's but with one less power, so the starting x³ would now become x², x² would become x, and so on

3x² + 1x - 3

Can somone pls help me with this I have a C- in math and I really need help also a like show work on each one plsss
Lady bird [3.3K]

Answer:

1. \frac{3}{8}

2. \frac{1}{4}

3a. -\frac{1}{4}

3b. 3

3c. -\frac{4}{5}

4. m = \frac{y_1 - y_2}{x_1-x_2}\\

Step-by-step explanation:

1.

Rises 6 inches for every horizontal change of 16 inches

Slope = rise/run

Slope = 6/16

Slope = 3/8

2.

Rises 3 feet for every horizontal change of 12 feet

Slope = rise/run

Slope = 3/12

Slope = 1/4

3a.

m = \frac{y_1 - y_2}{x_1-x_2}

m = \frac{3-2}{-2-2}

m = \frac{1}{-4}

m = -\frac{1}{4}

3b.

m = \frac{y_1 - y_2}{x_1-x_2}\\

m = \frac{-1 - 2}{-1-0}

m = \frac{-3}{-1}

m = 3

3c.

m = \frac{y_1 - y_2}{x_1-x_2}\\

m = \frac{1 - (-3)}{-1-4}\\

m = \frac{4}{-5}\\

m = -\frac{4}{5}

4.

m = \frac{y_1 - y_2}{x_1-x_2}\\
