Answer:
The y-variable will be eliminated when adding the system of equations.
There is only one solution to the system of equations.
Step-by-step explanation:
-x + 6y = 16 (1)
8x - 6y = -2 (2)
Add the equations to eliminate y
-x + 8x = 16 +(-2)
7x = 16 -2
7x = 14
x = 14/7
x = 2
Substitute x = 2 into (1)
-x + 6y = 16 (1)
-2 + 6y = 16
6y = 16 + 2
6y = 18
y = 18/6
y = 3
(x, y) = (2, 3)
(x - 8)(x + 6)
Then set each parenthesis equal to zero
Answers:
x = -6
x = 8
Answer:
An acute triangle
Step-by-step explanation:
If f(x) varies directly with 
If f(x) varies directly with x then we use equation f(x) = kx
where k is the constant of proportionality
So equation becomes 
We use the information and find out k
f(x)= 10



now we use the value of k and find the value of f(x) when x=3

f(x) = 10
The value of f(x) = 10 when x= 3
