You don't even have to actually do the division to find the correct answer.

The leading term of q(x) is x³/x² = x, so only the 1st and 3rd selections are appropriate.

The remainder r(x)/b(x) will have the divisor as b(x), so only ...
.. the 1st selection is appropriate.

This can be done using long division that we have learned with numbers, except that each digit in the numeric long division is replaced with a number that can exceed 10.

Thus we can write the division as where the right most digit represent a number, and each number to the left represent an increasing power of x.
                 ________________________
1 +2 +1    |  1   +10   +13     + 39

We will use a first quotient digit of 1 and begin the division

                 _1______________________
1 +2 +1    |  1   +10   +13     + 39
                   1     +2     +1                                   (subtract)

                            8     12      39


After that, we have a multiplier of 8 and continue

                 _1___8___________________
1 +2 +1    |  1   +10   +13     + 39
                   1     +2     +1                                   (subtract)

                            8     12      39
                            8     16        8                         (subtract)

                                    -4      31

This means that we have a quotient of (x+8) with a remainder of -4x+31
thus the final expression looks like

\frac{x^3+10x^2+13x+39}{x^2+2x+1}=x+8+\frac{-4x+31}{x^2+2x+1}

With a slope of m = -2 and a point being (5,-2) what’s the Y-intercept?
almond37 [142]

Answer:

c = 8

Step-by-step explanation:

Given the following data;

Slope, m = -2

Points (x, y) = (5, -2)

To find the intercept, c;

Equation of a straight line is given by the formula: y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

Substituting the values in order to find the intercept, we have;

-2 = -2(5) + c

-2 = -10 + c

c = 10 - 2

c = 8

Therefore, the y-intercept is 8.

Solve for x.<br> 7(1x - 3) = 4(x + 5)
alexandr1967 [171]

Answer:

x = 41/3

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

7(1x - 3) = 4(x + 5)

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Simplify:                                        7(x - 3) = 4(x + 5)
  2. Distribute:                                     7x - 21 = 4x + 20
  3. Subtract 4x on both sides:          3x - 21 = 20
  4. Add 21 on both sides:                  3x = 41
  5. Divide 3 on both sides:                x = 41/3

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitute:                    7(1(41/3) - 3) = 4(41/3 + 5)
  2. Multiply:                        7(41/3 - 3) = 4(41/3 + 5)
  3. Subtract/Add:               7(32/3) = 4(56/3)
  4. Multiply:                        224/3 = 224/3

Here, we see that 224/3 is indeed equivalent to 224/3. ∴ x = 41/3 is a solution to the equation.

And we have our final answer!
