Find the cost of 12 items if the cost function is C(x) = 2x +12

Mathematics
1 answer:
pantera1 [17]3 years ago

Answer:

$36

Step-by-step explanation:

we need to find the cost of 12 items, and the function of determining the cost is C(x)=2x+12, where x is the number of items (the input value of the function)

we know that there are 12 items, so in this function, x=12

substitute x as 12 in the function; the x in C(x) also gets substituted as 12, as 12 is the input value and the value of C(x) is the output

C(12)=2(12)+12

multiply

C(12)=24+12

add

C(12)=36

that means, for 12 items, the cost will be $36

Can I have some help finding the area to this? Can someone also explain how to figure this out?? PLEASE
nignag [31]
Let's separate the hexagon into 5 shapes; 2 triangles on each side, and a rectangle in the middle. Now let's find the area of each of the smaller shapes.

Top left triangle:
The equation to find the area of a triangle is
(base = b, height = h, a = area)
a = b · h · \frac{1}{2}
Now let's add in our values and solve.
a = 2 · 4 · \frac{1}{2}
a = 8 · \frac{1}{2}
a = 4

Now since there are 4 of these triangles, and they're all the same size,
4 · 4 = 16
All of the triangles put together = 16cm²

The middle rectangle:
The equation to find the area of a rectangle is simple:
(w = width, l = length, a = area)
a = w · l
Now let's put in our values and solve.
a = 4 · 8
a = 32

The rectangle is 32cm²

Now let's add the areas together. 
32 + 16 = 48

The answer is <span>48cm²

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

The slope of the line below is -2. Use the coordinates of the labeled point to
Vilka [71]

Answer:

We can express the equation for any linear equation with slope -2 and point (x0,y0) as:

y=-2x+(y_0+2x_0)\\\\y-y_0=-2(x-x_0)

Step-by-step explanation:

Incomplete question:

There is no point to complete the equation.

As we have no point to complete the linear equation, we will solve for any given point (x0,y0) and a slope of m=-2.

The linear equation can be written generically as:

y(x)=mx+b\\\\y(x)=-2x+b

If a point, like (x0,y0) belongs to the linear equation, it satisfies its equation. Then:

y_0=-2x_0+b

Then, we can calculate b as:

y_0=-2x_0+b\\\\b=y_0+2x_0

We can express the equation for any linear equation with slope -2 and point (x0,y0) as:

y=-2x+(y_0+2x_0)\\\\y-y_0=-2(x-x_0)

Nikitich [7]

Financial records  are important records and thus, needs to be saved safely. The method for solid system to keep it is: Option d. I, II, and III

<h3>How to safely keep financial records and why?</h3>

Financial records are records of all financial transactions and receipts. They're needed for future cases like some contradictions, to get past details, to analyze data to make prediction about future sale and for development of the organization etc.

For keeping them, they should be saved in an easily accessible, and hardly destroy-able place. So that its prevented safely but accessible faster with correct authentication.

For the given case, for solid system for keeping financial records, we can actually follow all the three steps provided.

I. Making a mental note of all purchases made during the week. II. Recording money spent in a hand-held notebook. III. Organizing receipts and transactions on a computer.

Thus,

The method for solid system to keep it is: Option d. I, II, and III
