Answer:
y-6=-1/3(x+6)
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(3-6)/(3-(-6))
m=-3/(3+6)
m=-3/9
simplify
m=-1/3
y-6=-1/3(x-(-6))
y-6=-1/3(x+6)
For a function like this, all you have to do is substitute 8 in for x.
f(8)=9(8)-10
f(8)=72-10
f(8)=62

13 - 3x = 4 (x - 2)
distribute 4 through the parenthesis
13 - 3x = 4x - 8
move variables to the left side and change its sighn
13 - 3x - 4x = - 8
move constant to the right side and change its sign
-3x - 4x = - 8 - 13
collect like terms
-7x = - 8 - 13
-3x - 4x = - 8 - 13
calculate the sum or difference
-7x = - 21
divide both sides of the equation by - 7
x = 3
Answer: 19x is the first answer 5x - 24 is the second answer

Hi there!
In order to figure out how many students are in each group, we'll need to find the greatest common factor of the two class sizes. The greatest common factor is 7. This means that 7 students are in each group.
Hope this helps!! :)
