Answer:

14) m=2

15) m=-1

16) m=0

Step-by-step explanation:

In order to calculate the slope of a line, we can use this formula:

m=\frac{y_2-y_1}{x_2-x_1}

The procedure is:

- Choose two points on line.

- Substitute the coordinates into the formula and evaluate.

Then:

14) Point (0,0) and Point (1,2):

Slope:  m=\frac{2-0}{1-0}=-2

15) Point (0,0) and Point (-2,2):

Slope:  m=\frac{0-2}{0-(-2)}=-1

16) Since it is an horizontal line, the slope is zero:

m=0

Triangle ABC and Triangle DEF are similar. For triangle ABC, AB = 2x , AC = 24 inches and BC = 20. For triangle DEF, EF = 5 and
Norma-Jean [14]
X=8.

Following the similarity statement, we know that AC is to DF as BC is to EF.  The ratio would be:

24/(x-2) = 20/5

Cross multiply:
24*5 = 20(x-2)

Use the distributive property:
120 = 20x - 40

Add 40 to both sides:
120+40 = 20x - 40 + 40
160 = 20x

Divide both sides by 20:
160/20 = 20x/20
8 = x

a regular polygon has a perimeter of 36 inches. each side is exactly 6 inches long. which figure does this discribe?
fgiga [73]
Since a side is only 6 inches long and the total perimeter is 36; take 36/6 and you get 6. The only figure with six sides is a hexagon, thus your answer is hexagon.
