Answer:

-8b - 32

Step-by-step explanation:

Distribute the 8 to each term in the parentheses:

8(-b) = -8b

8(-4) = -32

Add these two terms together:

-8b - 32 is the simplified expression

Hey there!

[tex]8(-b-4)[/tex]

Separate 8 and -b-4 with parenthesis and also add (-b+-4)

[tex](8)(-b+-4)\\(8)(-b)+(8)(-4)=-8b-32\\-8b-32[/tex]

[tex]-8b-32[/tex] is your answer.

Answer: The function is not one-to-one

Step-by-step explanation:

An one-to-one function is such that no two elements in the domain correspond to the same element in the range.

Now, we have the function:

y = f(x) = round(x)

Which rounds x to the nearest whole number.

Now, to round to the next whole number we must look at the first number after the decimal point.

If that number is 5 or larger, we round up

If that number is smaller than 5, we round down.

Then, for example:

f(1.2) = 1

because the first number after the decimal point is smaller than 5.

and:

f(1.1) = 1

f(1.2) = 1

f(1.2423) = 1

f(1.348)  = 1

So we have a lot (if x is real, we have infinite) values of x that are maped into the same value in the range.

Then this can not be an one-to-one function.

Answer:

-22

Step-by-step explanation: you only add when it is like -8-(-12) that means you add them together but in this case all you do is subtract -8-14 so basically you cancel out the plus sign. Hope this helps.

Step-by-step explanation:

If you look at the graph you can clearly see that the x coordinate 5 and the y coordinate -2 line up with point D

Answer:

Not a function

Step-by-step explanation:

Each input can have only have one output.

x(1) can't equal both -1 and 3 at the same time.

x(2) can't equal both 4 and 0 at the same time.

x(3) can't equal both 5 and 1 at the same time.

In other words there can't be multiple X's equalling different things.

Answer:

a. What is the mean price? Round your answer to the nearest cent. $679.63

b. What is the median price? $689.50

c. What is the mode price? $699

Step-by-step explanation:

The mean price, rounded to the nearest cent is $679.63, the median price is $689.5 and the mode price is $699.

The mean is the ratio of the sum of all numbers and total numbers in the list. The median is the middle value in a list ordered in ascending order. The mode is the most frequently occurring value on the list.

In our question, given data:

$699, $599, $699, $680, $590, $720, $650, $800

Mean is found by dividing by sum all the prices and then divided by total terms.

Sum all prices = ($699 + $599 + $699 + $680 + $590 + $720 + $650 + $800) = $5437

Mean = [tex]\frac{5437}{8}[/tex] = $679.625

The round of mean value to the nearest cent is $679.63.

To find median, arrange the data list in ascending order and then find the middle value. Since in our data list, there are 8 terms (even). Therefore take average of the two middle values to find median.

Ascending order ⇒ 590, 599, 650, 680, 699, 699, 720, 800

Midian = [tex]\frac{680 + 699}{2}[/tex] = $689.5

Mode is the most frequently occurring value in the data list, in our data list, 699 comes twice.

∴ Mode = $699

Hence Mean = $679.63, Midian = $689.5, Mode = $699.

Answer:

The wire is approximately 42feet long

Step-by-step explanation:

We can mentally sketch out the shape that is formed between the guy wire and the antenna tower. This is simply a right-angled triangle with the opposite side being the height of the antenna (30 feet). The adjacent side is the distance on the ground between the point where the wire was fastened and the base of the antenna.

The hypotenuse side is the length of the wire we are looking for.

Parameters are given as:

Opposite : 30ft

Adjacent: 30ft

Hypotenuse: x feet

The hypotenuse = [tex]\sqrt{opp^2 + adj^2}[/tex]

Hypotenuse =[tex]\sqrt{30^2+ 30^2} \approx 42ft[/tex]

Step-by-step explanation:

The drawing for this question is missing. I will attach it with the answer.

9.a) Plane JKL is not an appropriate name for the plane because all of three points lie in the same line.

Through a line pass infinite planes. The plane JKL doesn't define a unique plane. That's why plane JKL isn't an appropriate name for the plane.

9.b) We can name the plane using three points that don't lie in the same line.

Three possible names for the plane are :

Kareem's statement: 4:1 is equal to 12:9. Let's see if this is correct.

[tex]\bf Step ~1:[/tex]

We have to simplify the ratios. Since 4:1 is already simplified, we do not have to do anything with it. 12:9 could be simplified. To do so, we need to find the greatest common factor (GCF) of both numbers. The GCF of 12 and 9 is 3. Since 3 is the GCF for both numbers, we divide them by 3.

[tex]\bf 12 /3=4\\9/3=3[/tex]

First number: 4

Second number: 3

Ratio: 4:3

[tex]\bf Step~2:[/tex]

We compare the ratio 4:3 to 4:1. Since they have different values, they are not equivalent to each other.

[tex]\large\boxed{\bf Our~final~answer: ~Kareem~is~wrong.}[/tex]

[tex]\bf {Explanation~in~Step~1}[/tex]

4 : 1 and 12 : 9 are not equivalent

Kareem is wrong

Correct question:

Kareem says that the ratio 4:1 is equivalent to the ratio 12:9 because

4 + 8 = 12 and 1 + 8 = 9. Is Kareem correct? Explain how you know

4 : 1 is in its simplest form already

12 : 9

= 12/9

= 4/3

= 4 : 3

Therefore,

4 : 1 and 12 : 9 are not equivalent

Kareem is wrong based on his assumption that 4 + 8 = 12 and 1 + 8 = 9
