1)You add 9 to both side; so you subtract 9 from nine which leaves you 0
2)you subtract 9 from the other side, because you have to do the same things to both sides. so you get 7-9. Which equals -2.
3) you're equation will look like : p<-2
Russ says the students need 6 buses. Vickie says they need7 buses.Who is corret? Explain your reasoning.
Direct variation
Explanation:
Given –2 + 4y + 2 = 8x.
To find the given expression –2 + 4y + 2 = 8x is direct variation or not.
If y varies directly as x, then y = kx.
If y varies inversely as x, then
⇒ –2 + 4y + 2 = 8x
Combine like terms together.
⇒ –2 + 2 + 4y = 8x
⇒ 4y = 8x
Divide both sides of the equation by 4, we get
⇒ y = 2x
Which is in the format of y = kx.
Thus y varies directly as x.
Hence, –2 + 4y + 2 = 8x is direct variation.
