I hate maths pleas help

Answers

Answer:

These should be the answers you are looking for.

A: 62

B: 8.9

C: 2.8

This should be correct, but please tell me if it isnt.

Explanation:

The simplest way to figure this out is by counting how many marks there are on the number line. If the numbers are betweeen 1 and 2 on a number line for example, youll want to use decimals.

Example of a problem:

I--I--I--I--I--I--I--I--I--I--I

1               ^              2

Count the markings like this: 1.1, 1.2, 1.3, 1.4, 1.5 .

the furthest you can go with a decimal until you get a full number is 0.9.

If you are solving a question with full numbers (example: 20 through 30), you would count normally.

I--I--I--I--I--I--I--I--I--I--I

20           ^              30

The answer would be 25 for this one.

I hope this helps you out in the future.

Answer:

She had $150 in the beginning before she bought the swimming items.

Step-by-step explanation:

You have the right numbers for the equation but you also times the money she had in total.

The equation is x-3(44)=18

44 is the total for one daughter and you times that by three to get for three duaghters.

Then you multiply -3 and 44 which is -132.

Which would be x-132=18

Now you would move -132 to the other side which would be +132 →x=18+132

x=150

Noir drove from the Dead Sea up to Amman, and her altitude increased at a constant rate. When she began driving her altitude was 400 meters below sea level. When she arrived in Amman 2 hours later, her altitude was 1000 meters above sea level. Let y represent noir’s altitude in meters relative to sea level after x hours.

Answers

Answer:

y(x) = -400 m + (700 m/hr)x

Step-by-step explanation:

Let y = 0 represent sea level.  Noir's initial altitude was -400 m.  In two hours she went from -400 m to +1000 m, a positive change of 1400 m.  Thus, the rate of ascent was m = slope = (change in altitude) / (change in time), or

rate of ascent = 1400/2 m/hr  =  700 m/hr

Thus, an equation describing her altitude relative to sea level after x  hours is

y(x) = -400 m + (700 m/hr)x, where x is the number of hours of driving completed.  This formula correctly predicts the altitude after two hours:

y(2) = -400 m +  (700 m/hr)(2 hr) = 1000 m above sea level.

Bruno and Willie need a total of $50,000 to start an accounting business. Bruno has spent a lot of time getting the business set up, so Willie agrees to contribute $12,000 more than Bruno. How much money will Willie contribute?

Answers

The amount contributed by Willie and Bruno is $31000 and $19,000 respectively.

Let amount contributed by Willie be x

Let amount contributed by Bruno be y

Since Willie agreed to contribute $12,000 more than Bruno;

Therefore;

x - y = 12000....…....... equation (1)

x + y = 50,000...…....... equation (2)

By solving the system of equations simultaneously;

2x = 62000

x = 31000

and y = 50,000 - 31000

y = 19,000

In essence; The amount contributed by Willie and Bruno is $31000 and $19,000 respectively.

O{(-2, -6), (-1,2), (-2, – 7), (6,6)}
Submit Answer

Answers

Answer:

Option 4: {(-2, -6), (-1,2), (-2, – 7), (6,6)}

Step-by-step explanation:

Definitions:A function is a relation for which no two ordered pairs have the same first component (or x-values) and different second component (y-values). The set of first components is the input, also referred as the domain. The set of second components is the output, also referred as the range.

In order to determine whether a given relation is a function, one must always take notice of the x-values ⇒ make sure that an x-value does not have more than one corresponding y-value.

Solution:

Option 1:  {(-6, -9), (-2, -3), (–9,2), (2, -3)}  ⇒ This relation is a function. Each input has one corresponding output.

Option 2: {(-2,0), (-5,8), (7,9), (6,8)}   ⇒ This relation is also a function. Each input has one corresponding output.

Option 3: {(6,9), (-7,8), (1, –4), (8,8)}  ⇒ This relation is also a function. Each input has one corresponding output.

Option 4:  {(-2, -6), (-1,2), (-2, – 7), (6,6)} ⇒ This relation is not a function. The x-value, x = -2, has two corresponding y-values: y = -6, and y = -7.

Therefore, the correct answer is Option 4: {(-2, -6), (-1,2), (-2, – 7), (6,6)}.

Answer:

A line passes through the points (4, 6) and (8, 7). What is its equation in point-slope form?​

Answers

Hello there! :)

First, let’s find the slope.

We can find it using this formula:

m=y2-y1/x2-x1

m=7-6/8-4

m=1/4

So the slope is 1/4.

Now, we can use the point-slope formula:

y-y1=m(x-x1)

y-6=1/4(x-1/4)

Eric is a Missouri resident and a sentenced offender. He was sentenced to three years of probation with the following conditions:1. He must not violate any law of any state or any local ordinance.2. He must report to Probation Officer Greg James monthly at a predetermined time.3. He must not use any illegal substance or alcohol and must also submit to random testing.4. He must obtain permission from Probation Officer James before traveling out of Missouri.In his second year of probation, Eric was captured by store detectives stealing a satellite radio system from an electronics store in Orlando, Florida. The Orlando Police Department responded to the scene and investigated. After interviewing the store detectives, they issued Eric a misdemeanor appearance citation for shoplifting. The appearance citation contained a mandatory court date for the following month.Approximately three months later, Probation Officer James received a letter from the local district court in Orlando, Florida. The letter informed James that probationer Eric was in Orlando in January, received a misdemeanor violation for shoplifting, and has since failed to report for the scheduled court date; a warrant has now been issued by the Orlando District Court. James reviewed probationer Erics file and found no record of any request to leave the state for any type of travel. Erics home address is listed as Springfield, Missouri.Probation Officer James prepared all of the paperwork required to initiate probation revocation proceedings against Eric. James also sent Eric written notice that the terms of his probation had been breached and that his probation had been placed in jeopardy. The notice informed Eric that a hearing had been set for the probation revocation. During the hearing, Eric will have an opportunity to present evidence on his own behalf.On the date of the hearing, Eric and James arrived at the courthouse to present their arguments before the presiding judge. During the hearing, Probation Officer James presented evidence supporting the alleged breach of the conditions of probation. He presented sworn statements from Orlando store detectives regarding the shoplifting incident and sworn statements from the Orlando police officer who issued Eric the misdemeanor appearance citation. Eric responded to the allegations by testifying that the Orlando misdemeanor case was a case of mistaken identity and that he was at home in Missouri during that time. James rebutted Erics testimony by restating that his witnesses (through their sworn statements) could attest to the fact that Eric was in fact arrested in Orlando for shoplifting the satellite radio system on the date in question. At the close of all testimony, the judge sent the courtroom into a fifteen-minute recess so that he could review all of the testimony and reread the sworn statements from the absent witnesses.Approximately fifteen minutes later, the judge returned to the bench and announced his decision that Eric had violated the conditions of his probation agreement and should now be sent back to prison to serve out the remainder of the original sentence. The judge added that Eric will face the shoplifting charges upon release from prison. The court then served Eric with a written order stating all of the reasons for the probation revocation.Can Probation Eric be prosecuted for shoplifting after release from prison, or would that constitute double jeopardy?
