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.

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.

a point with a positive x-coordinate and a negative y- coordinate is reflected over the y-axis . what sentence will describe the coordinates of the new point ?

Answers

Answer:

The sentence that describes the reflected point (x,-y) over the y-axis

Step-by-step explanation:

Since not sure if specific options are available lets answer this question in a general notation.

Let us consider the Co-ordinate system in two dimensions (i.e.  and ); where the horizontal line represents the  values and the vertical line representes the  values.Now we are told that we have a point with a positive x-coordinate and a negative y-coordinate, thus:

This means our point is located at the 4th Quadrant (where  values are positive and  values are negative).

Reflecting it over the y-axis means that our point is now located on the 3rd Quadrant (where both  and  values are negative).

Therefore the new reflected point will now be:

''a point with a negative x-coordinate and a negative y-coordinate''

Answer:

the x-coordinate is negative, and the y-coordinate is negative

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.)

What is the resolution in Ares god of war?

Answers

Answer    Ares was a Olympian god of war, violence and destruction. He was not welcomed by both gods and mortals in Greek mythology, nor ancient Greeks themselves, well with the few exceptions such as Spartans and the Amazons. He is often compared with his half sister Athena who is also, like Ares, associated with war activities. However, while Athena is respected and appreciated for her warfare, strategy, courage and wisdom, Ares is seen as the force of destruction, savage warfare and bloodlust. No one really liked his activities because, wherever he went, he left traces of misfortune and aberration behind. Despite his unpopularity, he was worshiped and honored in Crete and Peloponnese, where military bases of Spartans could be found, as well as in Pontus, the northern part of modern greece.
