Answers

Answer:

-1/2

Step-by-step explanation:

1. The formula to find the slope given two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. Now, all we have to do is plug in the values.

2. (Solving)

[tex]\frac{(-6)-(-5)}{(-1)-(-3)}[/tex]  [tex]\frac{-6+5}{-1+3}[/tex] [tex]\frac{-1}{2}[/tex] [tex]-\frac{1}{2}[/tex]

Therefore, the slope is -1/2.

Answer:

B. - 1/2

Step-by-step explanation:

Use slope formula and substitute given coordinates:

[tex]m=(y_2-y_1)/(x_2-x_1)[/tex][tex]m =(-6-(-5))/(-1-(-3))=-1/2[/tex]

According to the synthetic division below, which of the following statements are true? Check all that apply.
-6)2 9 -12 2 -3 11

A. When x = -6,2x2 + 9x-7 = 11.
B. When x = 6,2x2 + 9x-7 = 11.
C. (x-6) is a factor of 2x + 9x- 7.
D. When (2x + 9x-7) is divided by (x - 6), the remainder is 11.
E. When (2x2 + 9x - 7) is divided by (x + 6), the remainder is 11. F. (x+6) is a factor of 2x2 + 9x-7.​

Answers

The last number on a synthetic division represents the remainder of the division.

The true statements are:

(a). When x = -6, 2x^2 + 9x - 7 = 11. (e). When (2x2 + 9x - 7) is divided by (x + 6), the remainder is 11.

From the question, we have the dividend to b 2x^2 + 9x - 7, the last number to be 11, and the zero of the divisor to be -6.

This means that:

[tex]x = -6[/tex] --- the divisor

Set to 0

[tex]x+6 = 0[/tex]

So, when the dividend 2x^2 + 9x - 7 is divided by divisor x + 6, the remainder is 11.

This also means that, when -6 is substituted for x in the dividend, the remainder is 11

Hence, the true statements are (a) and (e)
