A regular polygon has about 5 lines of symmetry. The number of lines of symmetry is equivalent to the number of sides.

Answer:

\frac{2(x-6)(x-10)}{(x-4)(x-5)}

Step-by-step explanation:

In essence, one needs to work their way backwards to solve this problem. Use the information to construct the function.

The function has verticle asymptotes at (x = 4) and (x = 5). This means that the denominator must have (x - 4) and (x - 5) in it. This is because a verticle asymptote indicates that the function cannot have a value at these points, the function jumps at these points. This is because the denominator of a fraction cannot be (0), the values (x - 4) and (x - 5) ensure this. Since if (x) equals (4) or (5) in this situation, the denominator would be (0) because of the zero product property (this states that any number times zero equals zero). So far we have assembled the function as the following:

\frac{()}{(x-4)(x-5)}

The function has x-intercepts at (6, 0), and (0, 10). This means that the numerator must equal (0) when (x) is (6) or (10). Using similar logic that was applied to find the denominator, one can conclude that the numerator must be ((x - 6)(x-10)). Now one has this much of the function assembled

\frac{(x-6)(x-10)}{(x-4)(x-5)}

Finally one has to include the y-intercept of (0, 120). Currently, the y-intercept is (60). This is found by multiplying the constants together. (6 * 10) equals (60). One has to multiply this by (2) to get (120). Therefore, one must multiply the numerator by (2) in order to make the y-intercept (120). Thus the final function is the following:

\frac{2(x-6)(x-10)}{(x-4)(x-5)}

candace help out at the library after school. The head librarian tells her that there are 2,160 books in the children's section
Slav-nsk [51]
That would be 40 books on each shelf. Hope that helped :)
Here is the process: 
2,160/ 9 stands = 240 books per stand
240 stands/ 6 shelves each = 40 books on each shelf.

Which of the following systems of inequalities would produce the region
Mnenie [13.5K]

Answer:

y > x + 1 ; y ≤ 10 ; x ≥ 0

Step-by-step explanation:

First, we need to get the equation of the straight line. The equation of the straight line is expressed as y = mx+c

m is the slope

c is the y-intercept

Using the coordinate points (0, 1) and (1,2)

m = (2-1)/(1-0)

m = 1/1 = 1

y-intercept c = 1 (the point where the line cuts the y-axis)

Substitute;

Since y = mx+c, then y = 1x + 1

y = x+1

Since the line is a broken line and shaded above, then y > x+1

Also, the point shaded on the graph indicates y ≤ 10 ; x ≥ 0
