The answer would be 19/6.
Answer:
1. Not a direct variation
2. Direct variation (constant= -4)
3. Direct variation (constant= -1)
Step-by-step explanation:
A direct variation is a function of the type
y = k*x, where k can be any real number
First case
1. y=4x+9
The term 9 interferes with the expression (it creates an offset for the value)
2. 2y=-8x
It is a direct variation, y = -4x
3. x+y=0
It is a direct variation, y = -x
Answer:
the correct answer is : option c)infinitely many
EXPLANATION:
infinite lines pass through a point . so, infinite solution is the correct answer
The expression is not simplified, because both the numerator and the denominator can be divided evenly
Start by adding 2 to both sides to get 3r^2 = 48. then divide both sides by 3 to get r^2 = 16. square root both sides to get r = 4.
