Simplify

Answer:  3*10^2

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

Work Shown:

7321 = 7000 + 300 + 20 + 1

7321 = 7*1000 + 3*100 + 2*10 + 1*1

7321 = 7*10^3 + 3*10^2 + 2*10^1 + 1*10^0

Side note: The exponents count down 3,2,1,0. You can think of a similar thing like 7x^3+3x^2+2x+1 and simply replace x with 10.

Answer:

you just gotta look and remember about the first 100 day depossit which would make the prices go up

Answer:

To find the answers, all I have to do is apply the operations (plus, minus, times, and divide) that they tell me to, in the order that they tell me to.

(f + g)(x) = f (x) + g(x)

= [3x + 2] + [4 – 5x]

= 3x + 2 + 4 – 5x

= 3x – 5x + 2 + 4

= –2x + 6

(f – g)(x) = f (x) – g(x)

= [3x + 2] – [4 – 5x]

= 3x + 2 – 4 + 5x

= 3x + 5x + 2 – 4

= 8x – 2

(f  × g)(x) = [f (x)][g(x)]

= (3x + 2)(4 – 5x)

= 12x + 8 – 15x2 – 10x

= –15x2 + 2x + 8

\left(\small{\dfrac{f}{g}}\right)(x) = \small{\dfrac{f(x)}{g(x)}}(  

g

f

​  

)(x)=  

g(x)

f(x)

​  

= \small{\dfrac{3x+2}{4-5x}}=  

4−5x

3x+2

​  

My answer is the neat listing of each of my results, clearly labelled as to which is which.

( f + g ) (x) = –2x + 6

( f – g ) (x) = 8x – 2

( f  × g ) (x) = –15x2 + 2x + 8

\mathbf{\color{purple}{ \left(\small{\dfrac{\mathit{f}}{\mathit{g}}}\right)(\mathit{x}) = \small{\dfrac{3\mathit{x} + 2}{4 - 5\mathit{x}}} }}(

Después de 40 días (11 de febrero)

Explicación paso a paso:

Dado que :

El avión 1 sale cada 8 días

El avión 2 sale cada 10 días

El avión 3 sale cada 20 días

Si todos se van el 2 de enero; La próxima fecha en que se irán juntos se puede obtener obteniendo el mínimo común múltiplo de los días de cada avión:

___8____10_____20

2 | _4____5______10

2 | _ 2____5______ 5

2 | _ 1 ____5______ 5

5 | _ 1 ____ 1 ______ 1

El mínimo común múltiplo es, por tanto;

2 * 2 * 2 * 5 = 40

Todos se irán juntos nuevamente después de 40 días:

(2 de enero + 40 días) = ​​11 de febrero

Answer:

The answer to the question is 5 (positive 5)

Answer: f(-5)= 7

Step-by-step explanation:

The x value is -5 so look for the y value of the x value which is 7

Answer:

f(-5) = 7

Step-by-step explanation:

f(x) is referring to the y value, so what it is equal to would be the x value at that spot

in this case the y value is -5 so the x value is 7

Answer:

yes

Step-by-step explanation:

Yes, he is correct because he pays $36 a month with the satellite TV receiver he payed $135 that month.\But if we do 36x12=432+99=531and the cable tv cost 45x12=540 so even when we add the satellite TV receiver price on his ours is still more expensive

The required month in which both pay the same amount is 11 months. And our friend is right, satellite tv is less expensive than Cable Tv.

Given that,
You pay $45 per month for cable TV. Your friend buys a satellite tv receiver for $99 and pays $36 per month for satellite TV.
To determine when you and your friend will have paid the same amount for TV services.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
let x be the number of months,
According to the question,

For the cost of cable TV = 45x
For satellite TV = 99 + 36x
Now,
99 + 36x = 45x
99 = 45x - 36x
9x = 99
x = 11

Now cost at 12 months,
Cable = 45 * 12 = 540
satellite = 99 + 36 * 12 = 531
So, satellite tv is less expensive than Cable Tv

Thus, the required month in which both pay the same amount is 11 months. And our friend is right.

Answer:

m = 2

Explanation:

Answer:

f(x)=-6

Step-by-step explanation:

f(0.5) means that x=0.5, so you substitute the x with .5 and multiply it times 2 which will get you 1. Then you subtract 7 to get -6.

Answer:

f(0.5)=-6

Step-by-step explanation:

f(x)=2x-7    f(0.5)

Just put in 0.5 for the x.

f(x)=2(0.5)-7

f(x)= 1 - 7

f(0.5) = -6

I hope you understand how to do these

Hope this helped :)

Answer:

x = 74, y = 53

Step-by-step explanation:

x and 106 are supplementary angles, they add to 180. 2y and x are also supplementary angles, and using substitution, you get 2y is equal to 106, so y is 53. x will be 74 degrees.

Answer: 72 nickels and 15 quarters

Step-by-step explanation:

72 times .05 = 3.6 or $3.60

15 times .25 = $3.75

Total = $7.35

.05 is representing the nickels and .25 is representing the quarters and if you take a calculator and do 87-72 you get 15 and you can set it up yourself to double check. But I wouldn't recommend doing it with pennies that's how I got confused so many times and you can also give yourself a similar problem if you want to make sure you know how to do it. Sorry if this was confusing.

Answer:

9h + 40

Since Jill earns 9 dollars per hour, you multiply the amount of hours she works by the amount she makes per hour (9h), then you add 40 which is a set amount.

y = 9h + 40

Answer:

Total = 36%

Step-by-step explanation:

Given

Company A = 0.15

Company B = 21%

Required

Determine the total revenue

Total is calculated as thus:

Total = Company A + Company B

Total = 0.15 + 21%

Represent 0.15 as %

Total = 0.15*100% + 21%

Total = 15% + 21%

Total = 36%

Answer:

C, 5/2

Step-by-step explanation:

3 I2x -1I + 4 = 16

Isolate absolute value:

3 I2x -1I + 4 - 4 = 16 - 4

3 I2x -1I= 12

(3 I2x -1I) / 3 = 12 / 3

I2x -1I= 4

Since the question is only asking for the positive, all you need to solve for is the +4. Solve for x

2x -1 = 4

2x -1 + 1 = 4 +1

2x = 5

2x / 2 = 5 / 2

x = 5/2 or C

Answer:

The shorter side is 8 feet

the longer side is 16 feet

Step-by-step explanation:

lets call the shorter side x.

let's call the longer side 2x (because it's twice as long as the shorter side)

you know that the perimeter is 48 feet.

the perimeter would be 2(short side) + 2(long side)

using this, you can make the following equation:

2(x) + 2(2x) = 48

open the parenthesis.

2x + 4x = 48

6x = 48

x = 8

2x = 16
