Answer:
2. No it is not direction variation
3. This is direct variation with the constant being 2
Step-by-step explanation:
The equation for direct variation is y=kx
2. 8y = 3x+1
Divide each side by 8
8y/8 = 3x/8 + 1/8
y = 3/8 x + 1/8
We are adding 1/8 to each time so it is not direct variation
3. 12y = 24x
Divide each side by 12
12y/12 = 24x/12
y = 2x
This matches y= kx, where k=2
This is direct variation with the constant being 2
Answer:
0.222222222
Step-by-step explanation:
Negative rate of change just means that the graph is falling. On this one, that's everywhere after x=0.5. The only choice that's completely in that section is the last one.
Answer:
3 4/8 or 3 1/2
Step-by-step explanation:
First thing you would have to do is making, 8 1/2, the denominator 8. so what is 4 x 2? 8. So then you would have to multiply the 1 by 4 and you would get 8 4/8. Subtract 8 1/2 and 5 7/8 and you get 3 4/8. Simplify and you would get 3 1/2
Answer:
90 fish have spots
Step-by-step explanation:
cross multiply and divide:
3 x 300 = 900
