1 - 2n > 5. The solution set is (-∞, -2)

Step-by-step explanation:

e are dealing here with two problems:

First, to determine which mathematical statement represents "One less than twice a number is no less than five".

Second, solve n, that is, the solution set for the numbers that solve the inequality.

First Part: Identifying the inequality

"One less than twice a number" can be written as  , where n is the unknown number.

If it is not less than five, thus it is greater (no less) than five. Then, the symbol here is  " > " (greater).

As a result: "One less than twice a number is no less than five" could be rewritten as "One less than twice a number is greater than five", or:

.

Second Part: Finding the solution set

The solution set for this inequality is as follows:

⇒

Subtract -1 from each member of the inequality:

⇒  ⇒  

Multiply each member of the inequality by  (or divide each member by -2). We have to remember here that when we multiply or divide an inequality by a negative number (-n), this inverts the inequality, that is:

The solution set is then , which is any value less than -2 (not including -2, because is < and not ≤), and we have infinite negative numbers with such a characteristic. We can write it mathematically as an interval notation:

Solution set for  is .

Answer:

Hint: x is a negative number.

Step-by-step explanation:

The equation is x + 12 = -6 and you are trying to find x. The easiest way to solve this equation is by first subtracting 12 from both sides. It would look like x + 12 - 12 = -6 - 12. Since positive 12 and negative 12 are opposite and equal, they cancel each other out. This can be drawn as well into circles and crossed out for every positive circle with a negative circle. As for -6 and -12, you can use the same method of drawing circles, (trust me they can be very helpful, especially for people like me who need to see it visually before getting a hang of it). Since both are negatives, you would have to add them together and that would give you x.

Answer:

Number of high quality version downloads = 880

Step-by-step explanation:

Let,

x be the number of standard version songs downloaded

y be the number of high quality version songs downloaded

According to given statement,

x+y=1600        Eqn 1

2.8x+4.1y=5624     Eqn 2

Multiplying Eqn 1 by 2.8 to eliminate x

2.8(x+y=1600)

2.8x+2.8y=4480     Eqn 3

Subtracting Eqn 3 from Eqn 2

(2.8x+4.1y)-(2.8x+2.8y)=5624-4480

2.8x+4.1y-2.8x-2.8y=1144

1.3y=1144

Dividing both sides by 1.3

[tex]\frac{1.3y}{1.3}=\frac{1144}{1.3}\\y=880[/tex]

Hence,

Number of high quality version downloads = 880

Answer: The seagull is faster

Step-by-step explanation:

An owl travels 8 1/3 miles in 3/4 hour. The miles per hour of the owl would be:

= 8 1/3 ÷ 3/4

= 25/3 ÷ 3/4

= 25/3 × 4/3

= 100/9

= 11 1/9 miles pee hour

A seagull travels 12 1/2 miles in 2/3 an hour. The miles per hour of the seagull would be:

=12 1/2 ÷ 2/3

= 25/2 ÷ 2/3

= 25/2 × 3/2

= 75/4

= 18 3/4 miles per hour

Based on the calculation above, the seagull is faster.

Answer:

11 1/9 miles per hour<---- owls speed

Sherry make 16 pies in 12.9 hours.

What is Division method?

Division method is used to distributing a group of things into equal parts.

Given that;

Sherry can make 5 pies in 4 hours.

Now,

Since, Sherry can make 5 pies in 4 hours.

So, Sherry can make 1 pies in = 4/5 hours.

Thus, Sherry can make 16 pies in = 16 x 4/5 hours.

                                                    = 64/5 hours

                                                    = 12.9 hours

So, Sherry make 16 pies in 12.9 hours.

Step-by-step explanation: 4(2)^3-10 = 22 then take that into 3(22)-4/2 = 31

The value of the composition of function g ( f ( 2 ) ) = 31

Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.

Given data ,

Let the first function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = 4x³ - 10

Let the second function be represented as g ( x )

Now , the value of g ( x ) is

g ( x ) = ( 3x - 4 ) / 2

The composition of function is g ( f ( 2 ) )

Now , the value of f ( 2 ) = 4 ( 2 )³ - 10

f ( 2 ) = 32 - 10 = 22

And , the value of g ( 22 ) = [ 3 ( 22 ) - 4 ] / 2

g ( 22 ) = 62 / 2 = 31

Hence , the value of the function is g ( f ( 2 ) ) = 31

She will be ready, and she will make it on time.

Step-by-step explanation:

Given:

[tex]Start\ Time = 10:20\ am[/tex]

[tex]Planting = 5\ hours[/tex]

[tex]Shower = 1\ hour[/tex]

Required

Will she be ready by 5pm?

First, we calculate the time spent in planting and taking shower.

[tex]Time\ Spent = Planting + Shower[/tex]

[tex]Time\ Spent = 5\ hours + 1\ hour[/tex]

[tex]Time\ Spent = 6\ hours[/tex]

Next, we calculate the end time. i.e. the time she'll finish these tasks.

[tex]End\ Time=Start\ Time + Time\ Spent[/tex]

[tex]End\ Time=10:20\ am + 6\ hours[/tex]

[tex]End\ Time=04:20\ pm[/tex]

Since 04:20 pm is less than 5pm, then she will be ready, and she will make it on time.
