Why, if two wrongs don't make a right, do two negatives make a positive in mathematics?

Answers

Answer 1

So, we can’t directly compare wrong with that of negative. Let me give an example. Let’s just think of Terrorism. Do you think there are positive and negative sides of terrorism? Mostly the answer would be no. There is no such things as positive and negative when we think of terrorism. But here we can directly say that Terrorism is always wrong whenever and wherever we talk about it.

I think now I have cleared your doubts about difference between wrong and negative. That’s why we can never say that two wrong can make a right. I hoped this helped!!

Answer 2

Final answer:

In mathematics, two negatives make a positive due to the rules of multiplication and addition. This rule is a fundamental property of mathematics and is consistent across various mathematical operations and contexts.

Explanation:

In mathematics, two negatives make a positive due to the rules of multiplication and addition. When two negatives are multiplied, the negative signs cancel each other out and result in a positive product. For example, (-4) x (-3) = 12, where both numbers are negative but the product is positive.

The same concept applies to addition as well. When two negative numbers are added, the negative signs combine and result in a negative sum. However, when two negative numbers are multiplied, the negative signs cancel out and produce a positive product.

It's important to note that this rule is a fundamental property of mathematics and is consistent across various mathematical operations and contexts.

Your baseball team has a goal to collect at least 160 blankets for a shelter. Team members brought 42 blankets on monday and 65 on wednesday . Write and solve an inequality to find out how many blankets the team has to collect on friday?

Answers

y=160-(65+42). so it's 53

Answer:

Atleast 53

Step-by-step explanation:

We are given that your basketball team has a goal  to collect atleast 160 blanket for a shelter.

Team member bought blankets on Monday =42

Team member bought blankets on Wednesday=65

We have to write an inequality and find the number of blankets  has to collect on Friday.

Let x be the number of blankets  bought by team members on Friday

According to question

[tex]42+65+x \geq 160[/tex]

[tex]107+x \geq 160[/tex]

Subtract 107 on both sides

[tex]107-107+x\geq 160-107[/tex]

[tex]x\geq 53[/tex]

Hence, team members bought atleast 53 blankets on Friday .

the product of three consecutive nonzero integers

Answers

Final answer:

To find the product of three consecutive nonzero integers, multiply the first number by the next two numbers in the sequence.

Explanation:

If the first integer is n, the next will be n+1 and the next to it will be n+2

The product of three consecutive nonzero integers can be calculated using the formula:

n * (n+1) * (n+2)= n(n^2 + 3n+ 2)=n^3 +3n^2 + 2n

where 'n' represents the first integer. For example, if we take 'n' as 2, the three consecutive nonzero integers would be 2, 3, and 4. So, the product would be 2 * 3 * 4 = 24= (2)^3+  3*(2)^2+ 2*2

To find the answer, we just simply use PEMDAS, which means:
Parentheses
Exponents
Multiplication
   (and/or)
Division
Addition
   (and/or)
Subtraction

Solve the problem in this order. Since no operations are in the parentheses, we can skip that. The first operation we will do is multiplication. I can't really explain multiplication here, but you hopefully already know it, so multiply -4.31 by 3.09. Although there are negatives and decimals, treat it as a normal multiplication problem while doing the math.

This will give you -13.3179, just move the decimal point down, and since a positive is being multiplied by a negative, the answer is negative. Once you have this number, just add it to -0.98. This is the same as subtracting, since it is negative, so in other words, just subtract 0.98 from -13.3179, and you have your answer.

This would be -14.2979, or roughly -14.2.

A culture started with 3000 bacteria. After 4 hours, it grew to 3,600 bacteria. Predict how many bacteria will be present after 10 hours. Round your answer to the nearest whole number. Use exponential growth formula

Answers

Hello Shannonrodrigue. You can solve this by setting up an exponential growth equation.

[tex]A = A_ob^t[/tex]
[tex]3600 = 3000b^4[/tex]

Now we solve for b
[tex]3600 = 3000b^4[/tex]
[tex]\frac{3600}{3000} = \frac{3000b^{4}}{3000}[/tex]
[tex]\frac{6}{5} = b^4[/tex]
[tex]\sqrt[4]{\frac{6}{5}} = \sqrt[4]{b^4}[/tex]
[tex]\sqrt[4]{\frac{6}{5}} = b[/tex]

Now that we have found b, we can use the equation [tex]A = 3000b^t[/tex] to predict how many bacteria will be present after 10 hours.
[tex]b = \sqrt[4]{\frac{6}{5}}[/tex]
t = 10
[tex]A = 3000b^t[/tex]
[tex]A = 3000\sqrt[4]{\frac{6}{5}}^{10} = 4732.3228 = 4732 [/tex]

Assuming you mean 2x-8y=7, we can start by multiplying the first equation by -2 and adding it to the second (to cross out the x), resulting in -18y=-5. After that, we can divide both sides by -18, resulting in y=5/18. Next, plugging that into 4x-2y=9, we have 4x-10/18=9. Adding 10/18 to both sides, we get 4x=9+10/18. After that, we can divide both sides by 4, resulting in x=(9+10/18)/4=

What is the equation of a line passing through the points 6,3 and -4,3 so y=?

Answers

Answer:

y=3

Step-by-step explanation:

The required line will be y = 3 which is passing through points (6,3) and (-4,3)

What is the slope of the line?

The slope of the line is defined as the gradient of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Assume two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

To determine the line of passing through points (6,3) and (-4,3)

We have been given two points :(6,3) and (-4,3)

Let the required line will be:

(y - y₁) =  [(y₂ - y₁)/(x₂ -x₁ )](x -x₁  )

Here

x₁ = 6, y₁ = 3

x₂ = -4, y₂ = 3

(y - y₁) =  [(y₂ - y₁)/(x₂ -x₁ )](x -x₁  )

Substitute values in the above formula

(y - 3) =  [(3 - 3)/(-4 -6 )](x -6 )

(y - 3) =  [(0)/(-10 )](x -6 )

(y - 3) = 0

y = 3

Therefore, the required line will be y = 3

What is parallelogram?"It is a quadrilateral with opposite sides parallel.""The opposite angles of parallelogram are equal. "

For given question,

Two of the angles in a parallelogram measure 5x° and 7x°

The measure of an angle opposite to 5x° is also 5x°

Similarly the measure of an angle opposite to 7x° is also 7x°

So, we have the four angles of parallelogram as 5x°, 7x°, 5x°, 7x°

We know, the sum of all angles of quadrilateral is 360°

⇒ 5x° + 7x° + 5x° + 7x° = 360°

⇒ (5 + 7 + 5 + 7) x = 360

⇒ 24x = 360

x = 15

First you have to distribute the 2x+11.
So multiply -4x2x and -4x11. 
5x-8x-44=13
Add all your like terms so 5x+-8x.
-3x-44=13. Now add 44 to both sides.
-3x= 57. Now divide both sides by -3 to get the x by itself. 
x=-19


5x-4(2x+11)=13

1)distribute the -4 to the numbers within the parenthesis.

5x-8x-44=13

2) next step you combine light terms.
''5x-8x=-3x''
so now you have -3x-44=13
3) add 44 on both sides
and you're left with -3x=57
4) divide both sides by -3 in order to solve for x; x divided by any number is always x, and 57divided by -3 is -19

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

The given equation is,

17 = -13 - 8x

Now to solve the equation following steps are followed :

adding 13 both the sides of the equation,

17 + 13 = -13 - 8x + 13

multiplying -1 both side

- 8x*(-1) = 30*(-1)

Solving them we get,

8x = -30

8x/2 = -30/2

Solving them we get,

4x = -15

dividing both side by 4

what is 50/12 in a mixed number

A fraction is when there is less than 1 whole i.e. 1/2
A mixed fraction is when there is more than 1 whole i.e. 1 3/4
A improper fraction is when there is more than 1 whole i.e. 50/12

As you may have observed, the thing which differentiates a mixed fraction from an improper fraction is that a mixed fraction's numerator is never bigger than it's denominator.
:)
50/12 is an improper fraction,
To convert this into a mixed fraction, we can find out how many times 50 fits in 12: 50/12 = 4.16666
So we know there are 4 wholes, which as twelfths are 48/12;
We can then observe the difference between 50 and 48 is 2 twelfths

So 50/12 as a mixed number/fraction is 4 wholes and 2 twelfths 
which can also be written as 4 2/12 and then simplified to 4 1/6
