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

QV=13

Step-by-step explanation:

We are given that  line segment QU is a median of triangle UVW.

QV=

We have to find the QV.

We know that

Median is that line segment of triangle which is dawn from one vertex of the triangle to the opposite side and divides the opposite side into equal two equal parts.

By definition of median of triangle , QU  divides the line segment VW into two equal parts

Therefore, QV=QW

Using subtraction property of equality

Using addition property of equality

Combine like terms

Using division property of equality

Substitute the value of x

Qv=

Hence, the values of QV=13

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
