I'll do number 20, 21, 22 for you.

20.  It is ±1, ±2, ±4, ±8.

21.   Reflected over the x-axis and down 4.

22. Common ratio = 25/5 = 5.

23.  Imaginary roots occur in pairs so there is also a root -5i.

The answer is c.

7. Write the slope-intercept form of the equation of the line graphed below.​
Stels [109]

Answer:

The answer to your question is y = \frac{-1}{2} x - 1

Step-by-step explanation:

Process

1.- Get to points of the line

    A (-2, 0)

    B (0, -1)

2.- Find the slope of the line

Slope = m = \frac{y2 - y1}{x2 - x1}

Substitution

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

3.- Find the equation of the line

              y - y1 = m(x - x1)

Substitution

              y - 0 = -1/2(x + 2)

Simplification

                   y = -1/2x - 1

Divide using long division. check your answers. 1. (x 3 – 13x 2 + 7x – 48) ÷ (x 2 + 3) 3. (x 3 + 5x 2 – 3x – 1) ÷ (x – 1) 5. (x

1. We can conclude that the result of the division is x-13 with a remainder of 4x-9, or in other notation: x-13+ \frac{4x-9}{x^2+3}. Check the steps in the first image.

3. We can conclude that the result of the division is x^{2} +6x+3 with a remainder of 2, or in other notation: x^{2}+6x+3+ \frac{2}{x-1}. Check the steps in the firts image.

5. We can conclude that the result of the division is x+1 with a remainder of 5, or in other notation: x+1+ \frac{5}{x-4}. Check the steps in the first image.

7. To check if x+4 is a factor of x^{3}+3x^{2}-10x-24, we are going to perform long division. If the result of the long division has no remainder, x+4 is a factor of x^{3}+3x^{2}-10x-24.
Since the result of the long division has no remainder, we can conclude that x+4 is a factor of x^{3}+3x^{2}-10x-24. Check the steps in the second image.

9. To check if x-3 is a factor of x^{3}+3x^{2}-10x-24, we are going to perform long division. If the result of the long division has no remainder, x-4 is a factor of x^{3}+3x^{2}-10x-24.
Since the result of the long division has no remainder, we can conclude that x-4 is a factor of x^{3}+3x^{2}-10x-24. Check the steps in the third image.

10. We can conclude that the result of the synthetic division is -2x^{2}+9x+5. Check the steps in the fourth image.
