A direct variation is a linear equation. It describes a simple relationship between two variables.
Example: if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3.
Hope this helped!! :)
4x+3 because you divide the number of each
Answer:
y = -1x + 5
Step-by-step explanation:
use the eqation y - y1 = m (x - x1)
plug in ur slope as m and you x and y points
y - 3 = -1 ( x -2 )
distribute the slope --> y - 3 = -1x + 2
add three to both sides --> y = -1x + 5
Answer:
10 students/van
48 students/bus
Step-by-step explanation:
(a) 13v+5b = 370
(b) 12v+10b = 600
(a) - (b)
v -5b = -230
v = 5b-230
12(5b-230) + 10b = 600
60b+10b -2760=600
70b=3360
7b=336
b=48
v = 5(48) - 230 = 10
v = 10
Let's check
12(10) +10(48) = 600
