Answer:

division

Step-by-step explanation:

you need to get x by its self. so divide by 5 on both sides and get x = 2

Answer:

A'(5,-1)

Step-by-step explanation:

90° clockwise= (y,-x)

Point=A(1,5)

A(1,5)=A'(5,-1)

Step-by-step explanation:

[tex]\text{The length between 2 points, } (x_1, y_1)\text{ and }(x_2,y_2)\text{ is determined by, }[/tex]

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]\text{The length between } (12, -22)\text{ and }(8, -30)\text{ is determined by, }[/tex]

[tex]d=\sqrt{(8-12)^2+(-30-(-22))^2}=\sqrt{4^2+8^2}=\sqrt{4^2(1+2^2)}=4\sqrt5[/tex]

Answer:

2

Step-by-step explanation:

2÷2 is 4 because 2×2 is 4 and it is asking that how many times two divided by four so A number 2 times two divided is four

Answer:

Step-by-step explanation:

Let the salary in the previous year = $ x

Now the salary = $ (x +1000)

This year savings = $ 5720

13% * (x + 1000)= 5720

0.13 *(x + 1000) = 5720

0.13*x + 0.13*1000 = 5720

0.13x + 130 = 5720        {subtract 130 from both sides}

         0.13x = 5720 - 130

        0.13x  = 5590    {Divide both sides by 0.13}

               x = 5590/0.13

x = $ 43000

Sandra's previous year salary = $ 43000

Answer:

91

Step-by-step explanation:

117/9 is 13 which means she earns 13 for each hour and for 7 hours it will be 13 multiply by 7 and that gives 91

Answer: The domain is 3/7, -6, and 4.

Step-by-step explanation:

In the case of rational expressions, we can input any value except for those that make the denominator equal to 0 (since division by 0 is undefined). In other words, the domain of a rational expression includes all real numbers except for those that make its denominator zero.

As the other answer mentioned, x = -6 and x = 4 are not in the domain, since they both make the denominator equal to zero, and thus the overall expression undefined. But x = 3/7 is allowed, since f (3/7) = 0.

Every other real number is also acceptable.

In interval notation, the domain is then

[tex](-\infty,-6) \cup (-6,4) \cup (4, \infty)[/tex]

Answer:

100

Step-by-step explanation:

Number of seat in sector A = number of rows * number of seats

                                             = 9 * 8

                                             = 72

Number of seat in sectorB = number of rows * number of seats

                                             = 4 * 7

                                             =28

Total seats  = 72 + 28 = 100

Answer:

2(2y+5)/2=37.2/2

2y+5=37

2y+5-5=37-5

2y=32

2y/2=32/2

y=16

the closest to that is y=8

Answer:

720 minutes

Step-by-step explanation:

Total phone bill = $127.95

Service plan fee = $19.95

Total cost per minute = 127.95 - 19.95

= $108.00

No. of minutes used = Total cost per minute / Rate per minute

= 108.00 / 0.15

= 720 minutes

Answer:

[tex]\displaystyle \frac{ 1 }{3} [/tex]

Step-by-step explanation:

we would like to compute the following limit:

[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{4 {n}^{2} + 3n } }{6n} [/tex]

if we compute the limit from numerator to denominator directly,we'd end up with

[tex] \dfrac{ \infty }{ \infty } [/tex]

which is an indeterminate form so we must do it in a different way. well to compute this limit,we can consider factoring method . notice that we can factor the numerator and that yields

[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{ {n}^{2} ( 4 {}^{} + \frac{3}{n} )} }{6n} [/tex]

remember that ,

thus we acquire:

[tex]\displaystyle \lim_{n \to \infty } \frac{ {n} \sqrt{ ( 4 {}^{} + \frac{3}{n} )} }{6n} [/tex]

reduce fraction:

[tex]\displaystyle \lim_{n \to \infty } \frac{ {} \sqrt{ 4 {}^{} + \frac{3}{n} } }{6} [/tex]

as n approaches to ∞ ,3/n approaches to 0 which yields:

[tex]\displaystyle \frac{ \sqrt{ 4 {}^{} } }{6} [/tex]

simplify square root:

[tex]\displaystyle \frac{ 2 }{6} [/tex]

reduce fraction:

[tex]\displaystyle \frac{ 1 }{3} [/tex]

hence,

[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{4 {n}^{2} + 3n } }{6n} = \boxed{ \frac{1}{3} }[/tex]

and we're done!

There are many examples to pick from, but one example is this:

The set of rational numbers (aka any fraction of two integers) is closed under the operation of division. Divide any two rational numbers and we get some other rational number.

However, the set of integers is not closed under division. If we divided 10 over 3, then we get 10/3 = 3.333 approximately which isn't an integer. So just because the set of integers is a subset of the rationals, it doesn't mean that the idea of closure follows suit from superset to subset.  

Side note: The term "superset" is basically the reverse of a subset. If A is a subset of B, then B is a superset of A.
