Answer:

That is an irregular octagon, as most octagons start in the form of a square and not more like a rectangle.

Robert and his coworkers brought 11 work trucks to a service station for oil changes. While there they also put 6 gallons of gas

Free_Kalibri [48]

Answer:

The cost of an oil change for 1 truck was $42

Step-by-step explanation:

Let

x -----> the cost of an oil change for 1 truck

y -----> the cost of gas for 1 truck

z ----> the total bill

we know that

$z=11[x+y]$

we have

$z=\$694.32$

$y=(6)(3.52)=\$21.12$

substitute and solve for x

$694.32=11[x+21.12]$

$x=(694.32/11)-21.12$

$x=\$42$

Read the passage below and summarise it in a minimum of 100 words:

muminat

Answer:

Find the summary below.

Step-by-step explanation:

The article compares the standard of healthy living some hundred years ago to what is obtainable in our world today. While the energy gained through food consumption some years ago was just adequate and at the right proportion, what is consumed today, supplies energy that is on an all-time high. This misuse of resources led to the development of sustainable development practices such as planting of trees, exercise routines which are done occasionally.

Another sustainable practice that can be done on a more regular basis is the use of jute or paper bags which are more biodegradable, instead of plastic bags. Finally, the article encourages the adoption of more sustainable practices because they can be more economical compared to the other practices that are presumed to be the status quo.

Choose the solution set represented by the following graph.

olga55 [171]

Answer:

The solution set represented by the following graph is:

{x | x∈ R, x < -2}

Step-by-step explanation:

Clearly from the figure we could see that the solution set is to the left of ' -2' and excluding the point '-2' since there is a open circle at -2.

This means that -2 is not included in the set.

Also in interval; form the set of points that belong to the solution set are:

(-∞,-2)

in set-builder form it is written as:

{x | x∈ R, x < -2}

In Exercises 17-20, find the value of x so that the function has the given value. 17. f(x) = 8x - 7; f(x) = 17

Nastasia [14]

Answer:

17.) x = 3

18.) x = -5

I couldn't do 19.) and 20.) for you because there are weird symbols that I believe you mistakenly input. But I'm sure you now get the gist of how to solve such problems. Peace <3

Step-by-step explanation:

All you really have to do for all of the problems is substitute your value of "x" for the function.

17.) f(x) = 8x - 7; f(x) =17

17 = 8x -7 ---- substitute 17 for f(x), add 7 on both sides

24 = 8x ------ divide 8 on both sides

x = 3

18.) g(x) = -4x + 7; g(x) = 27

27 = -4x + 7 substitute 27 for g(x), subtract 7 on both sides

20 = -4x

x = -5
