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

Answer 1
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 2

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.)

Answers

Answer:

78 - 83 - 88

Step-by-step explanation:

If you minus all the numbers together, you get

73 - 68 = 5

68 - 63 = 5

63 - 58 = 5

1) So, 73 + 5 = 78

2) Next is 78 + 5 = 83

3) Last, 83 + 5 = 88

Answers

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.

2. Add the numbers

3. Order summands

4. Subtract 10 from both sides of the equation

5. Simplify

Answer:

t=2

Step-by-step explanation:

Simplify both sides of the equation.

16=4+3(t+2)

16=4+(3)(t)+(3)(2) (Distribute)

16=4+3t+6

16=(3t)+(4+6)(Combine Like Terms)

16=3t+10

16=3t+10

Step 2: Flip the equation.

3t+10=16

Step 3: Subtract 10 from both sides.

3t+10−10=16−10

3t=6

Step 4: Divide both sides by 3.

3/2= 6/3= t=2

0 ≤ y ≤ 80, −1.45

0 ≤ x ≤ 55, −1.45

0 ≤ x ≤ 55, −0.6875

Answers

Answer: the answer is C
Hope It Helps

The domain of the given function is [0,55] and the average rate of change is -1.45 so option (C) is correct.

What is the range and domain of a function?

A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.

The domain is for the independent variable while the range is for the dependent variable.

The domain of a function is the set of input values that the function defines.

The function goes from x = 0 to x = 55 thus  0 ≤ x ≤ 55 will be the domain.

The average slope for (0,80) and (55,0)

⇒ (0 - 80)/(55 - 0) = -1.45

Hence "The domain of the given function is [0,55] and the average rate of change is -1.45".

Answer:

7.5

Step-by-step explanation:

Since the angle shown is 90 degrees we can deduce that the rest of the arc is 270 degrees therefore we can make the fraction:

270/360; 360 being the total angle measurement of a circle

270/360 simplifies to 3/4

The fraction represents how much of the circle that arc covers

Now we have to find the circumference which would be

2([tex]\pi \\[/tex])r

r = 5 therefore: 2([tex]\pi \\[/tex])5 = 10[tex]\pi \\[/tex]

Now that we have the circumference of the WHOLE circle we multiply it by 3/4 to find out the arc length

Which gives us 7.5[tex]\pi \\[/tex], or 23.55

The correct answer is 7.5
