Question

UHM MEDAL
SOMEONE HELP WITH LINEAR EQUATIONS OR SOMETHING

Answer 1

Matilda practices guitar for a total of 70 minutes every day. She spends 10 minutes more practicing the electric guitar than the acoustic guitar.

Write a pair of linear equations to show the relationship between the number of minutes Matilda practices the acoustic guitar every day (x) and the number of minutes she practices the electric guitar every day (y).

Answer 2

Answer 3

anyone ??

Answer 4

Idk

Answer 5

You need 2 lines to compare the amount of time she practices electric and acoustic.
70 minutes in total right?
10 more minutes on electric.

That means that she plays 40 minutes of electric, and 30 minutes of acoustic everyday.

You can make functions from that information now.

Answer 6

alright, but what about the linear equation ? could you help me with that ?

Answer 7

y=40x
y=30x

Answer 8

You can graph that and it's easy to see the relations of those 2.

Answer 9

@dtan5457 ,, the whole question is:

Part A: Write a pair of linear equations to show the relationship between the number of minutes Matilda practices the acoustic guitar every day (x) and the number of minutes she practices the electric guitar every day (y). (5 points)

Part B: How much time does Matilda spend on practicing the acoustic guitar every day? (3 points)

Part C: Is it possible for Matilda to have spent 50 minutes practicing the electric guitar every day? Explain your reasoning. (2 points)

Answer 10

I just gave you your functions for the linear equations. The rest are fairly easy if you understood what I said.
