-5 + 10m + -2m^2 simplify

whole numbers, plus their counterparts less than zero, and zero

Negative integers(less than 0) being: –1, –2, –3 exc.

Positive integers(more than 0) being: 1, 2, 3 exc.

Answer:

Integers are whole numbers like -3, -2, -1, 1, 2, 3, 4. They can't be fractions or decimals though

Answer:

undefined

Step-by-step explanation:

the slope is found by finding the change in y over the change in x. in this instance, you can do 9--5/-3--3... which is the same as 9+5/-3+3. the result is 14/0. Any fraction that has a denominator of zero is undefined, so the line would be straight up and down.

Answer:

|-9|,|9|

Step-by-step explanation:

Because all absolute values are positive, the only numbers that apply to your questionare 9 and |-9|

221 = 220 + 1 = 4 * 29 + 1

So

i ²²¹ = i ²²⁰ i ¹ = i ⁴*²⁹ i = (i ⁴)²⁹ i = 1²⁹ i = i

since i ⁴ = 1.

Answer: THE ANWSER IS B

Answer:

117

Step-by-step explanation:

The average of all 7 people is the total weight of the original 6 people, plus the weight of the 7th person, all divided by 7.

For problems like this involving an average of numbers that are "close" together, here is a different strategy for solving the problem that you might like to try.

The original 6 people have an average weight of 173, which is 8 pounds more than the average of all 7 people. So all together, the weight of those 6 people is 6*8=48 pounds over the 165 average. That means the 7th person's weight must be 48 pounds below the 165 average.

So the weight of the 7th person is 165-48 = 117 pounds.

Answer:

The 7th person weighted 117

Step-by-step explanation:

Average Value

The mean or average of a number n of measurements is defined as the sum of all values divided by n.

[tex]\displaystyle \bar x=\frac{\sum x_i}{n}\\[/tex]

The question gives us some input data. The average weight of n=6 people is [tex]\bar x=173[/tex]. With this information, we can set this relationship:

[tex]\displaystyle 173=\frac{\sum x_i}{6}[/tex]

From the above equation, we know the sum of the first 6 persons:

[tex]\sum x_i=6*173=1,038[/tex]

When a 7th person gets on, the new average gets down to 165 and n=7. The equation for the new average is:

[tex]\displaystyle 165=\frac{\sum x_i+X}{7}[/tex]

Note we have a new summand to the numerator. It's the weight of the 7th person. Let's solve for X:

[tex]\displaystyle 165=\frac{1,038+X}{7}[/tex]

Multiply by 7:

[tex]7*165=1,038+X[/tex]

Operate and swap sides:

[tex]1,038 +X=1,155[/tex]

[tex]X=1,155-1,038=117[/tex]

The 7th person weighted 117

Answer:

324

Step-by-step explanation:

This is because when rounding you multiply 55 by 6 that is equal to 330 which is near 324. However if you want the answer spot on it would be 294

Answer:

324

Step-by-step explanation:

so you would times 53.5 by 5.5 and you would get 294.25 so i rounded up and the most logical  estimation there was is 324 pounds  

Answer:

Answer:

total of 482

Step-by-step explanation:

He sold 1940

20% on first 500  

500 *.20 = 100 commission

Then 25% on the next 1000

1940 -500 = 1440 left

He has 1000

1000 * 25%

1000*.25 = 250 commission

1440-1000 = 440 left

440 at 30%

440*.30 =132 commission

Add together

100+250+132 = 482

Answer:

There are 14 horses and 21 chickens.

Step-by-step explanation:

First, you have to make expression for horse and chicken. So we can let x be the number of horses and y will be the number of chickens. Next, given that the total number of feet for both animals is 98 so you have to make simultaneous equation :

[tex]4x + 2y = 98[/tex]

( horse has 4 feet and chicken has 2 feet )

There are a total of 35 heads so the other equation will be :

[tex]x + y = 35[/tex]

Lastly, you have to solve it :

[tex]4x + 2y = 98[/tex]

[tex]2(2x + y) = 98[/tex]

[tex]2x + y = 49 - - - (1)[/tex]

[tex]x + y = 35 - - - (2)[/tex]

[tex](1) - (2)[/tex]

[tex]2x + y - x - y = 49 - 35[/tex]

[tex]x = 14[/tex]

[tex]substitute \: x = 14 \: into \: (2)[/tex]

[tex]14 + y = 35[/tex]

[tex]y = 35 - 14[/tex]

[tex]y = 21[/tex]

Answer: 3

Step-by-step explanation: 3/2 / 1/2 = 3

Answer:

It's 3 :)

Step-by-step explanation:

you just multiply the numerators and put them over 1.

so 3*1 is just 3. Hope this helps!

Answer:

what type of help do you want?

75%.

3 out of 4 means 3/4

And if you divide 3/4 the answer is .75

So multiply by 100( because to convert decimal to percent you have to multiply by 100, or move the decimal place two places to the right) and you get 75

Slap a percent sign on there and you have 75%

Answer:

m=4 or slope =4

Step-by-step explanation:[tex]m=\frac{y2-y1}{x2-x1\\}[/tex]

so [tex]m=\frac{12-4}{6-2}[/tex] which is the same as 8/2. So all in all the slope is 4.

Answer:

A

You can take the square root of the inequality x^2<4, which will make it x< plus or minus 2 (x<2, x<-2)

You know it is this answer because, the sign cannot be greater than or equal to since the circles aren't filled, and if you solve the other inequality, the answer you get does not match.

Answer:

51.2545454545

Step-by-step explanation:

Answer:

51.25....

Step-by-step explanation:

Replace x and Y with the points and solve:

4x  -2y

(-4,-1) = 4(-4) - 2(-1) = -16 +2 = -14

(-4,-4) = 4(-4) - 2(-4) = -16 +8 = -8

(2,-3) = 4(2) - 2(-3) = 8 + 6 = 14

(3,-5) = 4(3) -2(-5) = 12 +10 = 22

The minimum value ( lowest ) is -14, which would be (-4,-1)

Answer:

A

Step-by-step explanation:

====================================================

Explanation:

The left hand side of the first equation is x-3y

The left hand side of the second equation is 2x-6y = 2(x-3y). Note how it's simply double of the first expression x-3y

If we multiply both sides of the first equation by 2, we get

x-3y = 4

2(x-3y) = 2*4

2x-6y = 8

Meaning that 2x-6y = 8 is equivalent to x-3y = 4. Both produce the same line leading to infinitely many solutions. Each solution will lay along the line x-3y = 4.

We can say each solution is in the set {(x,y): x-3y = 4}

Which is the same as saying each solution is of the form (3y+4,y)
