A) give a verbal description of the subset of real numbers represented by the inequality or the interval, B) sketch the subset on the rest of real number line, and C) state whether the interval is bounded or unbounded

Answers

An inequality is an expression which makes comparison between unequal expressions i.e. both sides of the inequality sign are not equal.

The verbal description of [tex]x > 5[/tex] is the set of all real numbers greater than 5 The interval is bounded (right bounded to be precise)

The inequality is given as:

[tex]x > 5[/tex]

[tex]x > 5[/tex] means x greater than 5

So, the verbal description is as follows:

The set of all real numbers greater than 5

To sketch [tex]x > 5[/tex] on a number line, we consider the following:

> means greater than; so, the arrow on the number line must point to the right[tex]> 5[/tex] implies that the arrow must start on 5> also implies that the circle on 5 must be an open circle

See attachment for the sketch

To determine if the interval is bounded or not, we do the following.

[tex]x > 5[/tex] means that the x starts at a value greater than 5, and the value of x has no end.

This is represented as: [tex](5,\infty)[/tex]

Notice that 5 is at the right, while [tex]\infty[/tex] is at the left.

This means that the interval is bounded (right bounded to be precise)

Find the number of ways of arranging N people in a straight line, if two particular people must always be separated.

Answers

Answer:

It’s the number of ways N people can be arranged in a straight line without restriction minus the number of arrangements in which the 2 people are together.

The number of ways N people can be arranged in a straight line without restriction = N!

The number of arrangements in which the 2 people are together = the number of possible positions for the left-hand person multiplied by the number of people who can be that person, multiplied by the number of possible arrangements for the other N - 2 people

= (N - 1) * 2 * (N - 2)!

= 2 (N - 1)!

So the number of ways N people can be arranged in a straight line if 2 particular people must be separated = N! - 2(N - 1)!

Hello! I'm happy to help!

Question 13: First, we will need to find the value of x. We know that AB and BC are equal.

So, we can subtract x from both sides.

2x-8

-x

x-8

So, we get AB as x-8

x+17

-x

and BC as 17. We know that these are equal, so we need to find which x value will make them that way. In this case, x=25 because 25-8=17. We can now add back the x we removed earlier.

17+25=42

Therefore, both AB and BC have a value of 42. and AC will be the combined total.

42+42=84

So, for question 13, x=25, AB=42, BC=42, and AC=84.

Question 14: This question is similar, but we have an expression for AB and AC, instead of AB and BC. We still know that AB=BC, so we can also say that BC=x+6 also. To find x, we need to find a second expression that is equal to AC. We can ad AB and BC together to get that. (x+6)+(x+6)=2x+12. This expression is equal to the AC expression, so we can compare them to find x.

2x+12=3x-31

We need to single out the x on one side, by changing things in the same way on both sides.

2x+12=3x-31

-2x -2x

12=x-31

+31 +31

43=x

Now that we know our x value, we need to plug it in!

43+6=49

We now know that both AB and BC have a value of 49. Let's plug in the value for AC.

(43·3)-31

129-31

After plugging in the values, we know that AC is equal to 98. You could have also added AB and BC together, giving you 98 also.

To Summarize Question 14: x=43, AB=49, BC=49, AC=98.

Question 15: This one is very similar to the last, with a little more complexity to the expressions. First, let's simplify the expressions on AB and AC.

AB=3(3x-1) AB=9x-3

AC=5(2x+2) AC=10x+10

Now that we have the simplified expressions, let's solve. We need to find an equivalent expression for AC. We know that AB and BC are equivalent, and also add up to AC. We can copy the expression from AB to BC, and then add them

(9x-3)+(9x-3)=18x-6=AC

We now compare the two expressions in an equation to find x.

10x+10=18x-6

Again, we have to single out x on one side.

10x-10=18x-6

-10x -10x

10=8x-6

+6 +6

16=8x

This time, we need to divide both sides to single out x.

[tex]\frac{16}{8}[/tex]=[tex]\frac{8x}{8}[/tex]

2=x

Now that we have x, we need to plug it in to finish solving.

(9·2)-3

18-3

AB=15 BC=15

From here, you can do one of two things, add AB and BC together (easy), or plug in x for AC.

15+15=30 (10·2)+10

AC=30 20+10=30

AC=30

To Summarize Question 15: x=2, AB=15, BC=15, AC=30.

A truck can be rented from Company A for $120 a day plus $0.20 per mile. Company B charges $60 a day plus $0.40 per mile to rent the same truck. Find the number of miles in a day at which the rentals cost for company A and company B are the same.

please help..

Answers

Answer:

12 miles in a day.

Step-by-step explanation:

Variable x = number of miles

Company A: 120 + 0.20x

Company B: 60 + 0.40x

Set up an equation:

120 + 0.20x = 60 + 0.40x

60 + 0.20x = 0.40x

60 = 0.20x

12 = x
