For this case we have that the relationship is inverse.
Therefore, we have a function of the form:
We must find the value of k.
For this, we use any ordered pair, such as:
Substituting values:
Clearing k we have:
Then, the function is:
Answer:
The relationship between the variables in this table is an inverse variation.
A function to model is:
Recall that the equation of a line passing through two points (x1, y1 and (x2, y2) is given by the formula (y - y1) / (x - x1) = (y2 - y1) / (x2 - x1).
Given that the line passes through the points (-4, 10) and (-1, 5), the equation of the line is given by (y - 10) / (x - (-4)) = (5 - 10) / (-1 - (-4)) = -5 / 3
3(y - 10) = -5(x + 4)
3y - 30 = -5x - 20
<span>3y = -5x + 10
5x + 3y = 10
y = -5/3 x + 10/3</span>

Which one will we start with? I'll explain 21. multiply it out and the clean it up. you should end up with 140=A if I'm correct.
Answer:
Step-by-step explanation:
sum of angle of triangle is 180 degree
5x+8x+50degree =180 degree
13x= 180-50
13x= 130
x= 130/13
x=10
5x= 5*10=50degree
8x= 8*10 =80degree
