Answer:
3rd option
Step-by-step explanation:
A direct variation is expressed in this form:
y = kx
1. y - 4x = 8
y = 4x + 8 is not a direct variation
2. y + 2 = 7x
y = 7x - 2 is not a direct variation
3. y - 3x = 0
y = 3x is a direct variation
4. y = 5x - 2
y = 5x - 2 is not direct variation
Answer:
4x+16
Step-by-step explanation:
Just multiply x and 4 by 4 to get your answer.
Answer:
x = -1 ; y = 1
Step-by-step explanation:
x = -1
y = 1
Plug in the corresponding numbers to the corresponding variables:
y < -x + 1
(1) < -(-1) + 1
1 < 1 + 1
1 < 2 (True)
y > x
1 > -1 (True).
