8. To which subsets of the real numbers does the number 13 belong?

Answer:

9.461 × 10^17

Step-by-step explanation:

946,100,000,000,000,000 is 9.461x10^17

Answer:

[tex]x = 0[/tex] and [tex]x = -2[/tex]

Step-by-step explanation:

[tex]\frac{x}{2} = \frac{{x}^2}{x-2}[/tex]

Use cross multiplying to solve the equation.

[tex]x(x-2) = 2({x}^2)[/tex]

[tex]{x}^2 - 2x = 2{x}^2[/tex]

[tex]2{x}^2-{x}^2+2x = 0[/tex]

[tex]{x}^2 + 2x = 0[/tex]

Now factor it.

[tex]x(x+2) = 0[/tex]

Now split into two equations:

Equation A:

[tex]x = 0[/tex]

Equation B:

[tex]x + 2 = 0[/tex]

[tex]x = 0 -2[/tex]

[tex]x = -2[/tex]

Therefore, the solutions are x = 0 and x = -2.

Answer:

C. 7x-200=17700

Step-by-step explanation:

When you write an equation for the middle and lower row you can add them together to get 6x+200=1700 but you still must include the upper row so you add x which results in c. If you solve you get x=2500 and if you plug that back into you equations for the lower and middle rows and then add the upper row you get 17700.

Answer:

7x+200=17,700 because if you set up an equation for each level, the upper level is just x, the middle level is 2x=500, and the lover level is 4x- 300. if you add all 3 equations together and set it equal to 17,700, it equals 7x+200=17,700

The domain will be the integer numbers between 8 and 12 using the limits in other words 8 ≤ u ≤ 12

this is considering every player will bought only one uniform for the season

Hope this helped!

if thats not it read this and see if this works out

The domain of the function is

Step-by-step explanation:

Given : The total cost in dollars to buy uniforms for the players on a volleyball team can be found using the function c= 34.95u +6.25, where u is the number of uniforms bought.

If there are at least 8 players but not more than 12 players on the volleyball team.

To find : What is the domain of the function for this situation ?

Solution :

The total cost in dollars  c= 34.95u +6.25

Where, u is the number of uniforms bought.

Now, The number of uniforms bought depend on the number of players.

We have given that, there are at least 8 players but not more than 12 players on the volleyball team.

i.e, The number of players are between 8 to 12.

So, The domain of the function is

8< u < 12

the answer the last one 90

Answer:

90

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]g(x) = \frac{3}{2} x + 4 \\ [/tex]

To find g(2), substitute the value of x that's 2 into g(x). That is for every x in g(x) replace it with 2

We have

[tex]g(2) = \frac{3}{2} \times 2 + 4 \\ = 3 + 4[/tex]

We have the final answer as

Answer:

50°C = 122°F

Step-by-step explanation:

Formula:

(50°C × 9/5) + 32 = 122°F

Hope it helps!!

Answer:

The answer is 122°F

Step-by-step explanation:

[tex]formula \: (celcius° \times 9 \div 5) + 32[/tex]

F°=(c°×9÷5)+32

F°=(50°×9÷5)+32

F°=(50°×1.8)+32

F°=90+32

F°=122°F

Plug in the values for x, y, and z.

- (-8) - (6) - (-4)

8 - 6 + 4

2 + 4

Answer:

0.53 is the right answer its not 0.28 because I did the work and I got 0.53 by dividing

Step-by-step explanation:

Answer:

[tex]3n - 4 = - 2 + 2n \\ or \: 3n - 2n = - 2 + 4 \\ or \: n \: = + 2 \\ or \: n = 2 \\ therefore \: n = 2[/tex]

Thank you ☺️ ☺️

Steps:

3n - 4 = -2 + 2n

-2n              -2n

n - 4 = -2

   +4    +4

n = 2

Answer:

Two purchases were $30 apart.

Step-by-step explanation:

The mean price means the average price. The mean absolute deviation is how spread out the values are. So another synonym for spread out is apart so if you think about that the correct answer would be Two purchases were $30 apart.
