Problem: Four students tried to write 12x + 3y=9 in equivalent y= mx + b form.
Question: Did each student get an equation that is equivalent to the original Ax + By=C form?
If so, explain the reasoning for each step. If not, tell what errors the students made.

Answers

if you convert it to y=mx+b then you would have to subtract 12x from each side to make it 3y= -12x + 9 which if u divide by 3 is y=-4x + 3

Answer:

If they got y = -4x + 3 it is equivalent to the original.

Step-by-step explanation:

Common errors include leaving the y with a coefficient, forgetting to simplify all the terms or getting the slope wrong by using the opposite sign.

(If there are specific results included with the question, you could include them in the comments.)

Given that

There was a negative balance of −$13.55 in the account.

And Hayden made a deposit of $20 in order to pay the overdraft.

Determine an addition equation that represents the amount of money in his account.

According to the question, an addition equation that represents as

⇒ 20.00 + (-13.55) = 6.45

Hence, an addition equation is 20.00 + (-13.55) = 6.45 that represents the amount of money in his account.
