I believe it is 4^-5
2^6 (<span>2^-4/ 2^7)
=2^6(2^-4-+7)
=</span>2^6(2^-11)
=4^6-11
=4^-5

Graph the lines by finding the points of intersection with the axes (intercepts):

Ostrovityanka [42]

To solve this problem you must apply the proccedure shown below:

1. You have the following function:

$y=-\frac{1}{2} (x-1)$

2. You can rewrite it as following:

$y=\frac{(-x+1)}{2}$

3. The line intersects the y-axis when $x=0$ , therefore:

$y=\frac{(0+1)}{2}=\frac{1}{2} =0.5$

4. The line intersects the x-axis when $y=0$ :

$0=\frac{(-x+1)}{2}\\ 0=-x+1\\ x=1$

5. Now plot the points (0, 0.5) and (1,0) in a graph , as you can see in the figure attached.

Therefore, the answer is: The points of intersection are (0, 0.5) and (1,0).

OK so I don't want answers, I just want someone to walk me through this and teach me how to do it.

Serggg [28]

Answer:

352cm²

Step-by-step explanation:

The shape is a cuboid and it has 6 faces, and the opposite faces are equal, so I calculate 3 different faces and multiplied it by 2 to give me the total surface area. Therefore, total surface area = the addition of all the surface areas in the shape. And to get each surface area, you have find the area of each of the 6 faces, and add them together, to give you the total surface area.

A small junior college had an enrollment of 7,843 students in the year 1990 and 8,793 students in the year 2000. Let x=0 represe

abruzzese [7]

Correct answer is: (0,7843) and (10,8793)

Solution:-

Given that a junior college has an enrollment of 7843 students in 1990 and 8793 students in year 2000.

We have to write this data as (x,y) .

Where x= years after 1990 and y=number of students enrolled.

Since in 1990, 7843 students enrolled, x = 1990-1990=0

And y=7843.

Hence one ordered pair is (0,7843).

Let us find the years after 1990 for 2000 = 2000-1990 =10

Hence another ordered pair is (10,8793).
