Why is subtracting an expression similar to distributing a –1?
Please answer quick!!

Answers

Answer 1
Take the expression 2x - (x - 3). We know we can multiply everything by 1 and not change it; we know that if a variable does not have a coefficient with it, we can write a 1 beside it. That means we can write our expression as
2x - 1(x - 3). This helps us see the distributive property applies here:
2x - 1x - 1(-3)
2x - 1x - -3
2x - 1x + 3
1x + 3 = x + 3

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Brad, a teenager, saves up his monthly allowance over a period of six months to buy a pair of high-resolution headphones. He lends his friend, Jorge $10 from his savings. If Brad has $272 now.

Then a monthly allowance of Brad will be given as,

⇒ ($272 - $10) / 6

⇒ $262 / 6

⇒ $43.67

The amount of monthly allowance of Brad will be $43.67 per month.

In 1982 John Hinckley was on trial, accused of having attempted to kill the then US President Ronald Reagan. Hinckley was found not guilty by reason of insanity. The defense psychiatric reports found him to be insane while the prosecution reports declared him legally sane. In particular, the defense sought to establish that brain scan results like John Hinckley's appeared in a higher percentage of schizophrenics than of normal people his age.
During Hinckley's trial, an expert witness, Dr. Weinberger, told the court that when individuals suffering from schizophrenia were given computerized axial tomography (CAT) scans, the scans showed brain atrophy in 30% of cases compared with only 2% of scans done on normal people. Health records show that 1.5% of the people in the United States suffer from schizophrenia. Hinckleys CAT scan showed brain atrophy. Calculate the probability that Hinckley suffered from schizophrenia given his CAT scan showed brain atrophy.

Answers

Answer:

O.186 or 18.6%

Step-by-step explanation:

Let s = event of schizophrenia

B = brain atrophy

From our question we have:

P(s) = probability of those suffering from schizophrenia = 1.5% = 0.015

P(B|S) = probability of brain atrophy = 30% = 0.30

P(S') = 1 - 0.015 = 0.985

P(B|S') = 2% = 0.02

Probability Hinckley suffered from schizophrenia

= P(S|B) = P(B|S)P(S)/P(B|S)P(S)+P(B|S')P(S')

= (0.30x0.015)/(0.30)*(0.015)+(0.02)(0.985)

= 0.0045/0.0045+0.0197

= 0.0045/0.0242

= 0.185950

This is approximately 0.186 or 18.6%

52 time 2 equals 104

104=104

Answer:

[tex]\boxed {\tt D. \ x=52}[/tex]

Step-by-step explanation:

The 2 angles are 2x and 76. They are on a straight line together. Therefore they are supplementary and add to 180 degrees.

[tex]2x+76=180[/tex]

Solve for x by isolating x on one side of the equation.

76 is added to 2x. The inverse of addition is subtraction. Subtract 76 from both sides of the equation.

[tex]2x+76-76=180-76\\2x=180-76\\2x=104[/tex]

x is multiplied by 2. The inverse of multiplication is division. Divide both sides of the equation by 2.

[tex]2x/2=104/2\\x=104/2\\x=52[/tex]

x is equal to 52 and D is the correct answer.

In how many ways can we write a number using the digits (0,2,3,5) and the number is greater than 100

Answers

This is a multiplicative principle's question. Let's think how we can solve that.

If we want numbers are greater than 1000, so we need numbers with 4 digit (for example: 1001, 2350 and so on).

Imagine that we need to complete four spaces: one thousands, hundreds, tens and ones. See below how to compelete each space:

One thousands: In this space, we can't use the number 0, because in this way, the number will have 3 digits and we want number with 4 digits (for example: 0235 is a 3 digits number). Therefore, we can use the numbers 2, 3 and 5 to complete this space. So, there are 3 possibilities.

Hundreds: Now, we can use the number 0 and the number won't have 3 digits (for example: 2035 is a 4 digits number). Therefore, we can use the numbers 0, 2, 3 and 5 to complete this space. So, there are 4 possibililities.

Tens: Ih this case, it happens the same thing that happen in the case of hundreds. Therefore, there are 4 possibilites.

Ones: Finally, in this case it also happens the same thing that happen in the case os hundreds. So, there are 4 possibilites.

For multiplicative principle, we just need multiply these numbers of possibilities to find the result of this question:

[tex]3\times4\times4\times4=192[/tex]

Therefore, we can write 192 numbers using the digits (0, 2, 3 and 5) and all these numbers are greater than 1000.

How is multiplying complex numbers different
from adding or subtracting complex numbers?

Answers

Let P and Q be two complex numbers such that

P = a+bi

Q = c+di

Where a,b,c,d are real numbers and i = sqrt(-1).

This means i^2 = -1.

-------------------

Adding P and Q means

P+Q = (a+bi)+(c+di)

P+Q = a+bi + c+di

P+Q = (a+c) + (bi+di)

P+Q = (a+c) + (b+d)i

As you can see, we just add the corresponding components together.

-------------------

Subtraction is a similar story.

P-Q = (a+bi)-(c+di)

P-Q = a+bi - c-di

P-Q = (a-c) + (bi-di)

P-Q = (a-c) + (b-d)i

We subtract the corresponding components

-------------------

Multiplication is a bit more complicated.

We'll use the FOIL rule

P*Q = (a+bi)*(c+di)

P*Q = a*c + a*di + bi*c + bi*di

P*Q = a*c + ad*i + bc*i + bd*i^2

P*Q = a*c + ad*i + bc*i + bd*(-1)

P*Q = a*c + ad*i + bc*i - bd

P*Q = (ac - bd) + (ad*i + bc*i)

P*Q = (ac - bd) + (ad + bc)i

Unfortunately multiplication isn't as simple as addition or subtraction, but we can at least make a tidy formula for it. You could also use the box method to visually organize the terms into a table to help multiply out P and Q.

So Michael lives 13/5 miles away from the school.

Sarah lives 1/2 as long as Michael.

So the distance from the school of where Sarah's house located is 1/2 distance from the school of where Michael's house located.

Which means :
