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.
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.)
Could someone help me with these two questions? Would really appreciate it. (Constant rate of change.)

Write the equation of the parabola in vertex form.
Vertex (2,3), point (1,-4)
Answer:what grade math is this
Step-by-step explanation:
Answer:
f(x) = -7(x - 2)^2 +3
Step-by-step explanation:
Vertex form is f(x) = a(x - h)^2 + k. plugin -4 for f(x). leave the variable a. plugin 1 for x and 2 for h. Lastly, plug in 3 for k. Then slove the expression for a. Once you find a plug it in for the a variable, plug 2 in for the h and plug 3 in for the k.

The Pacific Ocean is approximately _______
A)8
B)9
C)13
D)20 ...............
...............times larger in area than the Southern Ocean.
Answer: A. 8
Step-by-step explanation:
6.0061 x 10^7
= 6/8 x 10^7/10^6
7.8483 x 10^6
0.75 x 10^7-6
0.75 x 10^1
A: 0.75 = 7.5 = 8.
Answer:
A.
Step-by-step explanation:
6.0061 x 10^7
= 6/8 x 10^7/10^6
7.8483 x 10^6

Hayden accidentally overdrafted his bank account, so there was a negative balance of −$13.55 in the account. He then deposited $20.00 to cover the overdraft.
Write an addition equation that represents the amount of money in his account.
Enter your answer as an addition equation, formatted like this: 42+(-53)=-11
Do not enter the $ symbol. Do not enter any units.
Answer:
20.00-(13.55)= 6.45 in his bank account
Step-by-step explanation:
An addition equation is 20.00 + (-13.55) = 6.45 that represents the amount of money in his account.
What are Arithmetic operations?Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Operators which let do basic mathematical calculations
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
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.
