In a triangle the midline joining the midpoints of two sides is parallel to the third side and half as long ⇒

2(3x + 2) = 2x + 20
6x + 4 = 2x + 20
6x - 2x = 20 - 4
4x = 16
x = 16/4
x = 4

midsegment = 3x + 2 = 3*4 + 2 = 12 + 2 = 14

The value of y varies directly with x, and y=28 when x=7. Find y when x=4 by first finding k.

lesya692 [45]

Direct proportionality is the type of proportionality where an increase in one quantity or variable causes a corresponding increase in another quantity.
Therefore; y varies directly as x
Hence; y α x
y =k x where k is a constant
if y= 28 and x = 7 , then k = 28/4 =4
hence, y = 4 k
when x = 4, then y= 16
