Hey bro! Can you help me? Its about direct variations.
Yeah sure! Your house or mine?
Okay!Let's go there!
(1) Remember to write the right equation and that direct variations are solved using the equation, y = kx
If x varies directly as y, and x = 9 when y = 6, find x when y = 15 is the example
(2) You use the information given in the problem to find the value of k. In this case, you need to find k when x = 9 and y = 6.
what's the next step?
Rewrite the equation from step 1 substituting in the value of k found in step 2.
Use the equation found in step 2 and the remaining information given in the problem to answer the question asked. In this case, you need to find x when y = 15.
Then what's next?
That's it! for direct variations
And aside from direct variations the other types of variations such as joint, inverse and combined
Tomorrow, I will teach you about other kinds of variations and lend you my notes on the topic.
Really? Omg! It get it now.Thanks bro. It was a great help.
You're welcome.If you need help with your subjects, don't hesitate to ask me, bro.
