Points S,U, and T are the midpoints of the sides of PQR. Which statements are correct ? 1/2QP=UT 1/2TS=RQ SU=PR SU||RP UT=RP
cricket20 [7]

Answer:

\frac{1}{2} QP = UT

Step-by-step explanation:

GIVEN : In ΔPQR

              S is the mid point of QP

              U is the mid point of PR

              T is the mid point of  QR

Solution :

i) is true i.e \frac{1}{2} QP = UT

Refer the attached file

By mid segment theorem i.e. In a triangle, the line joining the midpoints of any two sides will be parallel to the third side and that same line joining the midpoints is also half of length of third side .

UT is the line joining the two mid points . So, by theorem given above UT is parallel to PQ and  1/2QP=UT.

So, (i) statement is true i.e. \frac{1}{2} QP = UT

I need help with my algebra II!!
sweet-ann [11.9K]
1st:
f(x) = x^2.
f(x +1):  Anywhere we see x we replace it with (x+1)

f(x+1) = (x+1)^2 , Expand
(x+1)^2 = (x+1)(x+1) = x^2 + 2x + 1=  C.

2nd:
Noting general equation, y = mx + c
m = slope,  c = vertical intercept.
From the graph, slope =  (2,0) and (0, -4)
=  (-4 -0) / (0 - 2) = -4/-2 = 2.
Vertical intercept, c = -4.
y = mx + c ,  y = 2x + (-4),    y = 2x - 4 =  D.

3rd:
f(x) = x^2 - x,  f(-4).  we would substitute x = -4.

f(-4) = (-4)^2 - (-4) = 16 + 4 = 20 = D.
Cheers.

Can the angles with measures 80o , 55o and 65o form angles on a line
garik1379 [7]

Answer:

Nope, this is because the angles in a triangle add up to 180, whereas these values added are equal to 200 degrees
