Answer:

1/2

Step-by-step explanation:

When its talking about the result or output, look at the range, and then follow the line(s) back to the number(s) in the domain. Do the opposite when it's talking about the function of a certain number, e.g. f(4).

The length of a rectangle is 2 cm less than twice the width. The area of the rectangle is 112 cm2. Find the length and width of

ELEN [110]

Let breadth be x

Length=2x-2

We know

$\boxed{\sf Area=Length\times Breadth}$

$\\ \sf\longmapsto 112=x(2x-2)$

$\\ \sf\longmapsto 2x^2-2x-112=0$

$\\ \sf\longmapsto x=-7\:or\:x=8$

Ignore negative value

Now

$\\ \sf\longmapsto Length=2x-2=2(8)-2=16-2=14$

$\\ \sf\longmapsto Breadth=8$

Solve x TN = 8 nV =x - 2?

AleksandrR [38]

Answer:

Step-by-step explanation:

STUV is a parallelogram.

TV and SU are its diagonals intersecting at point N.

Diagonals of a parallelogram bisects each other.

Therefore, TN = NV

8 = x - 2

8 + 2 = x

10 = x

x = 10

Find the slope of the line that passes through the pair of points.<br> (6, 1), (-6, 1)

GrogVix [38]

Answer: m = 0

Step-by-step explanation: To find the slope of the line, we can use the graphing method. To do this, we start by plotting our two points.

Let's label (6, 1) as point A and (-6, 1) as point B.

Now, graph our line through the 2 points.

Now remember that the slope, or m, is equal to

the rise over run from point A to point B.

To get from point A to point B, we rise o units and run -12 units.

So our slope or rise / run is 0/-12 which simplifies to 0.

This should make sense because we have a horizontal or flat line and

remember that the slope of any horizontal or flat line is 0.
