Line segment qu is a median of triangle uvw. find qv, if qv = 7x–1 and qw = 4x+5.

Step-by-step explanation:

we know that

A median of a triangle is a line segment from one vertex to the mid point on the opposite side of the triangle.

so

In this problem

If QU is a median of triangle UVW

then

QV=QW

substitute the given values

Solve for x

Find out the length of segment QV

substitute the value of x

answer: she must produce at least 9,000 windows in order to make a profit of $48,000

explanation:

48,000 - 12,000 = 36,000

36,000/4 = 9,000
