(-1,3) (3,0) (-1.-2) find perimiter

≈

Step-by-step explanation:

Find the distance between the three pairs first using the distance formula:

Take the first two points, and insert the values:

Simplify parentheses (two negatives makes a positive):

The distance between the first two points is 5. Use the nest two points, and insert values:

Simplify parentheses:

The distance between the nest two point is about 4.5. Use the remaining two points, and insert values:

Simplify parentheses (two negatives makes a positive):

The distance between the last points is 5. Add the distances together to find the perimeter of the triangle:

The perimeter is about 14.5.

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
