Answer:
Check the figure a for the complete solution.
<em>Translation in Portuguese:</em> Verifique a figura a para a solução completa.
Step-by-step explanation:
Complete os espaços com os números da tabela, de forma que a soma dos valores em todos os círculos seja zero.
Como
5 + (-2) + (-3) = 5 - 2 - 3 = 0
10 + (-2) + (-8) = 10 - 2 - 8 = 0
0 + (-8) + (8) = 0 - 8 - 8 = 0
-11 + 3 + (8) = -11 + 3 + 8 = 0
-9 + 3 + (6) = -9 + 3 + 6 = 0
-15 + (9) + (6) = -15 + 9 + 6 = 0
-15 + (5) + (10) = -15 + 5 + 10 = 0
-7 + (10) + (-3) = -7 + 10 - 3 = 0
Check the figure a for the complete solution.

Hi again
x² - 2x - 8
Factor
= (x + 2)(x -4)
Answer : A is the correct option.
If you wanna check if A is the right answer, I will solve it for you and it will you give you the exact answer which will be x² - 2x - 8
(x+2)(x-4)
Distribute
(x)(x) + (x)(-4)+(2)(x)+(2)(-4)
= x² - 4x + 2x - 8
= x² - 2x - 8
Here it is, we find the exam answer.
Thus, (x+2)(x-4) is the reciprocal of x² -2x - 8
I hope that's help !
Answer:
1/3
Step-by-step explanation:
perpendicular lines have slopes that are opposite reciprocals
Solution:
To find the equation of line passing through points A (1, 3) and B (3, 7).
we know that, to derive the equation of a line we first need to calculate the slope of the line. Slope m of a line at points 
and 
is given by - 
.
Slope of the line at point A(1,3) and B(3,7)
.
.
.
Equation of a line using a point and a slope , 
The equation of line passing through points A (1, 3) and B (3, 7) :
$18 + $10 = $28
1/3 + 1/3 = 2/3
3/3 - 2/3 = 1/3
$28 = 1/3
Answer is C. $28
