A triangle has certified C (1,4), D (-2,2) and E (3,1).

Determine the equation for the median from vertex C.

The equation for the median from vertex C is

Step-by-step explanation:

we know that

The median of a triangle is a line segment joining a vertex to the midpoint of the opposite side

In this problem

Is a line segment joining vertex C to the midpoint segment DE

step 1

Find the midpoint segment DE

we have

D (-2,2) and E (3,1)

The formula to calculate the midpoint between two points is equal to

substitute the given values

step 2

Determine equation of the median

The median passes through the points

C(1,4) and M(0.5,1.5)

Find the slope

The formula to calculate the slope between two points is equal to

substitute the values

Find the equation in point slope form

we have

substitute

Convert to slope intercept form

Isolate the variable y

therefore

The equation for the median from vertex C is

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12

11

step-by-step explanation:

32.50-7.50=25

225/25=11
